ACE (Emulator)

2024-04-08T15:12:49Z

OffseT: /* Web links */

[[File:ACE.png|thumb|German GUI - Main window]]'''ACE''' is a high quality [[Amstrad]] CPC/CPC+ emulator written by Philippe "[[OffseT|OffseT]]" Rimauro.

It is developed exclusively for [http://www.morphos.de/ MorphOS] as a user-friendly and fully OS-compliant application.<br />
Also, PulkoMandy is maintaining a port for [https://www.haiku-os.org/ Haiku] which tries to match the features of the original version as much as possible.

ACE was coded from scratch, using a real CPC as a reference in order to provide one of the best Amstrad CPC emulator ever. Most of the games and demos for both CPC and CPC+ are working perfectly; the quality of the emulation is often superior to what the existing CPC emulators on PC/Windows can produce.

In addition to the high quality emulation, ACE features full screen and overlay display (including 50Hz display), editor and analyzer windows for all emulated CPU and chipsets, advanced breakpoints management, a very powerful set of AREXX commands for cross-development, a plugin interface, scripting capabilities, and much more...

Moreover, ACE is fully translated in French, Spanish, German and English and is still under active development.

Also worth mentioning is [[ACE-DL]], an emulator available for Windows, macOS and Linux, which uses the same emulation engine as ACE but with a minimalist GUI (SDL-based), no localization, no scripting capabilities, and no support for external plugins.

== Emulator capabilities ==

ACE emulates most CPC hardwares and their variants.

=== System ===
* Handling of the entire CPC and CPC+ range.
* Full Z80 emulation.
* Up to 256 expansion ROMs.
* Up to 4 MiB of extended memory.

=== Video ===
* Accurate CRTC emulation of the various CRTC types.
* Gate Array full emulation of all variants (perfect split rasters management).
* CPC+ ASIC full emulation (unique quarter-cycle precision).
* CTM644, GT65 and MM12 monitors emulation (including dynamic analog behaviors).

=== Audio ===
* Full and very accurate PSG emulation (AY-3-8912).
* Extremely accurate audio DMA emulation on CPC+.

=== Devices ===
* Accurate but incomplete FDC emulation (Format and Scan instructions are missing).
* Accurate emulation of both floppy disc drives (real rotation speed computation, manual drive & side switches support).
* CPC+ Cartridge port emulation (including upcoming extended cartridges).
* Emulation of the tape interface through audio files (read only).
* Accurate emulation of the keyboard (including ghost keys when pressing more than three keys at once).
* Automatic keyboard remapping can be activated if your are using ACE with a keyboard layout unknown by the original CPC firmwares.
* Plugins interface to support virtually any external device.

== Graphical interface ==

ACE MUI graphical interface is designed to be versatile and very easy to use, and everything is always updated in real time to match the actual emulator state.

* Simple and modular configuration of the CPC profiles to emulate using tool types (from Ambient) or arguments (from CLI).
* Ability to change the CRTC type or the screen monitor model on-the-fly without having to reset the running program.
* SNA and DSK files management (all of them!) with automatic on-the-fly detection and fix of the corrupted DSK.
* CPR files management for CPC+ cartridges (including support of extended cartridges up to several hundreds on megabytes).
* Overlay support with real pixel aspect ratio.
* Full screen support with the ability to choose the graphic mode to use in order to get back the 50Hz smoothness if your screen monitor can do this.
* Maskable interface in both windowed & full screen modes.
* Floppy disc drives LED activity OSD when the interface is not displayed.
* Rich breakpoints management on predefined conditions (HBL, VBL, interrupt...), on graphical coordinates, on execution addresses, on memory accesses and on I/O ports accesses (with the ability to use complex conditions, masks on the break address and/or the break value) with the option to execute scripts.
* Video beam cursor to see the cathode's ray position while on pause or in step by step mode.
* Memory editor (management of all RAM and ROM switching, automatic detection of the character code page depending on the installed firmware ROM).
* Z80 disassembler with highlight on opcodes and fast jump buttons on branch instructions.
* CRTC editor (full real time read/write access to the registers).
* Z80 editor (full real time read/write access to the registers).
* Gate Array analyzer (palette display, graphic mode, interrupt internal counter).
* PSG analyzer (played notes, tuning, and a bunch of rich information from the current PSG settings).
* Hard sprites analyzer (palette and content).
* DMA analyzer (full real time state and instructions being executed).
* Video information window (frequencies, beam ray position...).
* Virtual keyboard and joysticks.
* Ability to map joystick to keyboard when in case real joystick is available.
* Internal keyboard matrix state observer.
* Screen monitor settings window (type, brightness, vertical hold).
* Sound volume control.
* Online help and MUI's bubbles help available everywhere to help the beginners.

== Programmable interface ==

ACE is designed to be expandable and controllable. You are not limited to the core emulation and can you easily integrate it in any cross-development tool chain.

=== Plugins ===

ACE support plugins that allow anybody with some C language knowledges to add support for expansions connected to joystick, printer or expansion CPC port.

==== Default ====
* Both [[joystick]]s (up to three fire buttons, also including an unique combined mode) using real devices plugged on the host machine (using USB or whatever).
* [[Printer]] (redirected to a file).
* [[Multiface_II|Multiface Two]] (well known hardware debugger and snapshot handler).
* [[Digiblaster|Digiblaster/Soundplayer]] (8-bit mono sound card).
* [[Kempston Mouse]].
* [[AMX Mouse]].
* [[Gunstick]] (light gun).
* [[Amstrad Magnum Phaser]] (light gun).
* [[Trojan Light Phazer]] (light gun).
* [[West Phaser]] (light gun).

==== Additional ====
* [[Albireo]] (MicroSD, USB, and more).
* [[X-Mass]] (IDE interface).
* [[Dandanator]] (programmable game cartridge module)
* [[Play2CPC]] (Amstrad Plus compatible game cartridge module, with embedded additional 3 voices PSG sound card)
* [[Nova]] (NV-RAM and RTC).
* [[MultiPlay]] (additional mice and joysticks ports).
* [[Willy]] (18 channels FM synthetizer and MIDI sound cards).
* [[PlayCity]] (6 voices PSG sound card).
* [[Amdrum]] (8-bit mono sound card).
* [[Amstrad_SSA-1_Speech_Synthesizer|SSA-1]] (English speaking speech synthesizer).
* [[Dk%27tronics_Speech_Synthesizer|DK'Tronics Speech]] (English speaking speech synthesizer).
* [[TMPI speech synthesizer|Techni-Musique Speech]] (multilingual speaking speech synthesizer).
* [[Mirage Imager]] (hardware freeze and snapshot handling).
* Cycle counter (developer helper).

=== Scripting ===

Any scripting language (such as Python, Lua or of course AREXX) can be used to control ACE through its AREXX interface. It gives you full control on the emulator in order to automate things (and much more), or even to use ACE as a powerful cross-development station (including integration into an IDE).

ACE-DL has a rewind feature, but it is not as good as it could be: [https://youtu.be/wIKGvpnJLUo Demonstration of rewind in ACE-DL]

Only the RetroArch CPC emulator has a proper rewind feature: [https://youtu.be/YwilYlSe5LQ Demonstration of rewind in RetroArch]. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

A very simple approach would be to make a SNA for each frame and limit the RAM snapshot to 128KB, which is ok for 99% of CPC software. For a 10-seconds long rewind functionality, only 64MB RAM is needed (128KB * 50 frames * 10 seconds).

A more efficient approach is to store only the values that are changed in RAM between two frames, so that RAM can be restored when rewinding. This allows for long rewinds, even of a CPC equipped with a 4MB RAM expansion. Proof of it is the GBA emulator [https://youtu.be/Sfc_1NKbiKg SkyEmu demonstrating super long rewind] while needing very few RAM.

For debugging, going back to the previous instruction is easily implemented. The emulator has to store the time when the previous instruction was executed so that he can go back to that instruction. In the same way, emulators can provide access to the previous HBL, IRQ, VBL, etc.

= Emulator Detection =

If you want to promote usage of real CPC computers, you can detect CPC emulators by:
*Checking if the memory is initialized with zeroes, as real machines have random memory values at boot
*Focusing on the minute details in Z80, CRTC and PPI chips. They are most often wrong in emulators
*Examining the FDC chip. It is only replicated more or less superficially in all emulators because the internals of the chip are still unknown

Combining these methods will definitely get you a 100% success rate in detecting emulators, even the toughest ones.

= Printers =
Support for CPC printers is abysmal in all emulators.
The only emulators that at least do some print rendering emulation are JavaCPC and Caprice Forever.

= Rewind feature =
ACE-DL has a rewind feature, but it is not as good as it could be: [https://youtu.be/wIKGvpnJLUo Demonstration of rewind in ACE-DL]

Only the RetroArch CPC emulator has a proper rewind feature: [https://youtu.be/YwilYlSe5LQ Demonstration of rewind in RetroArch]. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

A very simple approach would be to make a SNA for each frame and limit the RAM snapshot to 128KB, which is ok for 99% of CPC software. For a 10-seconds long rewind functionality, only 64MB RAM is needed (128KB * 50 frames * 10 seconds).

A more efficient approach is to store only the values that are changed in RAM between two frames, so that RAM can be restored when rewinding. This allows for long rewinds, even of a CPC equipped with a 4MB RAM expansion. Proof of it is the GBA emulator [https://youtu.be/Sfc_1NKbiKg SkyEmu demonstrating super long rewind] while needing very few RAM.

For debugging, going back to the previous instruction is easily implemented. The emulator has to store the time when the previous instruction was executed so that he can go back to that instruction. In the same way, emulators can provide access to the previous HBL, IRQ, VBL, etc.

= Emulator Detection =

If you want to promote usage of real CPC computers, you can detect CPC emulators by:
*Checking if the memory is initialized with zeroes, as real machines have random memory values at boot
*Focusing on the minute details in Z80, CRTC and PPI chips. They are most often wrong in emulators
*Examining the FDC chip. It is only replicated more or less superficially in all emulators because the internals of the chip are still unknown

Combining these methods will definitely get you a 100% success rate in detecting emulators, even the toughest ones.

ACE (Emulator)

2024-04-07T18:34:47Z

OffseT:

[[File:ACE.png|thumb|German GUI - Main window]]'''ACE''' is a high quality [[Amstrad]] CPC/CPC+ emulator written by Philippe "[[OffseT|OffseT]]" Rimauro.

It is developed exclusively for [http://www.morphos.de/ MorphOS].<br />[[PulkoMandy]] is maintaining the port for [https://www.haiku-os.org/ Haiku].

Also worth mentioning is [[ACE-DL]], a derivative version of ACE with its unique strengths and available for Windows, macOS and Linux (implementing an old school minimalist SDL GUI only, also with no scripting or external plugins support).

ACE was coded from scratch, using a real CPC as a reference in order to provide one of the best Amstrad CPC emulator ever.

Most of the games and demos for both CPC and CPC+ are working perfectly; the quality of the emulation is often superior to what the existing CPC emulators on PC/Windows can produce.

In addition to the high quality emulation, ACE features full screen and overlay display (including 50Hz display), editor and analyzer windows for all emulated CPU and chipsets, advanced breakpoints management, a very powerful set of AREXX commands for cross-development, a plugin interface, and much more...

Moreover, ACE is fully translated in French, Spanish, German and English and is still under active development.

== Emulator capabilities ==

ACE emulates most CPC hardwares and their variants.

=== System ===
* Handling of the entire CPC and CPC+ range.
* Full Z80 emulation.
* Up to 256 expansion ROMs.
* Up to 4 MiB of extended memory.

=== Video ===
* Accurate CRTC emulation of the various CRTC types.
* Gate Array full emulation of all variants (perfect split rasters management).
* CPC+ ASIC full emulation (unique quarter-cycle precision).
* CTM644, GT65 and MM12 monitors emulation (including dynamic analog behaviors).

=== Audio ===
* Full and very accurate PSG emulation (AY-3-8912).
* Extremely accurate audio DMA emulation on CPC+.

=== Devices ===
* Accurate but incomplete FDC emulation (Format and Scan instructions are missing).

* Maskable interface in both windowed & full screen modes.
* Floppy disc drives LED activity OSD when the interface is not displayed.
* Rich breakpoints management on predefined conditions (HBL, VBL, interrupt...), on graphical coordinates, on execution addresses, on memory accesses and on I/O ports accesses (with the ability to use complex conditions, masks on the break address and/or the break value) with the option to execute scripts.
* Video beam cursor to see the cathode's ray position while on pause or in step by step mode.
* Memory editor (management of all RAM and ROM switching, automatic detection of the character code page depending on the installed firmware ROM).
* Z80 disassembler with highlight on opcodes and fast jump buttons on branch instructions.
* CRTC editor (full real time read/write access to the registers).
* Z80 editor (full real time read/write access to the registers).
* Gate Array analyzer (palette display, graphic mode, interrupt internal counter).
* PSG analyzer (played notes, tuning, and a bunch of rich information from the current PSG settings).
* Hard sprites analyzer (palette and content).
* DMA analyzer (full real time state and instructions being executed).
* Video information window (frequencies, beam ray position...).
* Virtual keyboard and joysticks.
* Ability to map joystick to keyboard when in case real joystick is available.
* Internal keyboard matrix state observer.
* Screen monitor settings window (type, brightness, vertical hold).
* Sound volume control.

== Programmable interface ==

ACE is designed to be expandable and controllable. You are not limited to the core emulation and can you easily integrate it in any cross-development tool chain.

=== Plugins ===

ACE support plugins that allow anybody with some C language knowledges to add support for expansions connected to joystick, printer or expansion CPC port.

==== Default ====
* Both [[joystick]]s (up to three fire buttons) using real devices plugged on the host machine (using USB or whatever).
* [[Printer]] (redirected to a file).
* [[Multiface_II|Multiface Two]] (well known hardware debugger and snapshot handler).
* [[Digiblaster|Digiblaster/Soundplayer]] (8-bit mono sound card).
* [[Kempston Mouse]].
* [[AMX Mouse]].
* [[Gunstick]] (light gun).
* [[Amstrad Magnum Phaser]] (light gun).
* [[Trojan Light Phazer]] (light gun).
* [[West Phaser]] (light gun).

==== Additional ====
* [[Albireo]] (MicroSD, USB, and more).
* [[X-Mass]] (IDE interface).
* [[Dandanator]] (programmable game cartridge module)
* [[Play2CPC]] (Amstrad Plus compatible game cartridge module, with embedded additional 3 voices PSG sound card)
* [[Nova]] (NV-RAM and RTC).
* [[MultiPlay]] (additional mice and joysticks ports).
* [[Willy]] (18 channels FM synthetizer and MIDI sound cards).
* [[PlayCity]] (6 voices PSG sound card).
* [[Amdrum]] (8-bit mono sound card).
* [[Amstrad_SSA-1_Speech_Synthesizer|SSA-1]] (english speaking speech synthesizer).
* [[Dk%27tronics_Speech_Synthesizer|DK'Tronics Speech]] (english speaking speech synthesizer).
* [[TMPI speech synthesizer|Techni-Musique Speech]] (multilingual speaking speech synthesizer).
* [[Mirage Imager]] (hardware freeze and snapshot handling).
* Cycle counter (developer helper).

=== Scripting ===

Any scripting language (such as Python, Lua or of course AREXX) can be used to control ACE through its AREXX interface. It gives you full control on the emulator in order to automate things (and much more), or even to use ACE as a powerful cross-development station (including integration into an IDE).

ACE (Emulator)

2024-04-07T18:30:37Z

OffseT: /* Additional */

[[File:ACE.png|thumb|German GUI - Main window]]'''ACE''' is a high quality [[Amstrad]] CPC/CPC+ emulator written by Philippe "[[OffseT|OffseT]]" Rimauro.

It is developed exclusively for [http://www.morphos.de/ MorphOS].<br />[[PulkoMandy]] is maintaining the port for [https://www.haiku-os.org/ Haiku].

Also worth mentioning is [[ACE-DL]], a derivative version of ACE with its unique strengths and available for Windows, macOS and Linux.

ACE was coded from scratch, using a real CPC as a reference in order to provide one of the best Amstrad CPC emulator ever.

Most of the games and demos for both CPC and CPC+ are working perfectly; the quality of the emulation is often superior to what the existing CPC emulators on PC/Windows can produce.

In addition to the high quality emulation, ACE features full screen and overlay display (including 50Hz display), editor and analyzer windows for all emulated CPU and chipsets, advanced breakpoints management, a very powerful set of AREXX commands for cross-development, a plugin interface, and much more...

Moreover, ACE is fully translated in French, Spanish, German and English and is still under active development.

== Emulator capabilities ==

ACE emulates most CPC hardwares and their variants.

=== System ===
* Handling of the entire CPC and CPC+ range.
* Full Z80 emulation.
* Up to 256 expansion ROMs.
* Up to 4 MiB of extended memory.

=== Video ===
* Accurate CRTC emulation of the various CRTC types.
* Gate Array full emulation of all variants (perfect split rasters management).
* CPC+ ASIC full emulation (unique quarter-cycle precision).
* CTM644, GT65 and MM12 monitors emulation (including dynamic analog behaviors).

=== Audio ===
* Full and very accurate PSG emulation (AY-3-8912).
* Extremely accurate audio DMA emulation on CPC+.

= Printers =
Support for CPC printers is abysmal in all emulators.
The only emulators that at least do some print rendering emulation are JavaCPC and Caprice Forever.

= Rewind feature =
ACE-DL has a rewind feature, but it is not as good as it could be: [https://youtu.be/wIKGvpnJLUo Demonstration of rewind in ACE-DL]

Only the RetroArch CPC emulator has a proper rewind feature: [https://youtu.be/YwilYlSe5LQ Demonstration of rewind in RetroArch]. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

A very simple approach would be to make a SNA for each frame and limit the RAM snapshot to 128KB, which is ok for 99% of CPC software. For a 10-seconds long rewind functionality, only 64MB RAM is needed (128KB * 50 frames * 10 seconds).

A more efficient approach is to store only the values that are changed in RAM between two frames, so that RAM can be restored when rewinding. This allows for long rewinds, even of a CPC equipped with a 4MB RAM expansion. Proof of it is the GBA emulator [https://youtu.be/Sfc_1NKbiKg SkyEmu demonstrating super long rewind] while needing very few RAM.

For debugging, going back to the previous instruction is easily implemented. The emulator has to store the time when the previous instruction was executed so that he can go back to that instruction. In the same way, emulators can provide access to the previous HBL, IRQ, VBL, etc.

= Emulator Detection =

If you want to promote usage of real CPC computers, you can detect CPC emulators by:
*Checking if the memory is initialized with zeroes, as real machines have random memory values at boot
*Focusing on the minute details in Z80, CRTC and PPI chips. They are most often wrong in emulators
*Examining the FDC chip. It is only replicated more or less superficially in all emulators because the internals of the chip are still unknown

Combining these methods will definitely get you a 100% success rate in detecting emulators, even the toughest ones.

= CPC cartridge slot =
Emulator support for a CPC cartridge slot is as follows:
*[[M4 Board]] simulates a standard Plus cartridge port on the CPC and handles standard CPR files. M4 Board is emulated by CPCemu
*[[Plus2CPC]] brings a standard physical Plus cartridge port to the CPC. It is not supported by emulators
*[[Play2CPC]] is an evolution of the [[Plus2CPC]], adding RMR2 Plus mapping, R/W cartridge support, CRTC cursor raster interrupt and a 3-channel soundchip conforming to the [[PlayCity]] base spec. Play2CPC is emulated by ACE
*[[Dandanator]] brings a non-standard physical cartridge port and a very exotic non-standard memory mapper that spies on Z80 instructions (sacrificing compatibility without any justification). It is emulated by ACE, Retro Virtual Machine, CPCEC, ZEsarUX, DSP

= Mass-storage =

*[[Dobbertin Harddisc]] is emulated by MAME
*[[UIDE Universal IDE adapter cards for Z-80 computers|uIDE]] is emulated by Arnold
*[[Symbiface II]] IDE/PATA interface or compatible ([[X-Mass]], [https://github.com/salafek/cyboard-for-cpc Cyboard]) is emulated by ACE, Caprice Forever, MAME, WinAPE, WinCPC, Arnold, Virtual CPC

*[[M4 Board]] is emulated by CPCemu
*[[Vortex Winchester Drive]], [[ULIfAC|USIfAC / ULIfAC]] and [[Symbiface 3|Symbiface3 / RSF3]] are not supported by emulators

= Audio devices =
Emulator support is as follows:
*[[Amstrad SSA-1 Speech Synthesizer|SSA-1 speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME
*[[Dk'tronics Speech Synthesizer|Dk'Tronics speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME

*[[PlayCity]] is fully emulated by ACE, MAME, Arnold, SugarBox. The audio part of [[PlayCity]] is emulated by Caprice Forever, JavaCPC, CPCEC
*[[Play2CPC]] implements the PlayCity base spec (aka Arcade Sound System). It has one additional soundchip instead of two and no CTC chip. It is emulated by ACE
*[[Willy|Willy OPL3]] is emulated by ACE
*[[Willy|Willy MIDI]] is emulated only by ACE for Haiku
*[[Music Machine]], [https://github.com/lambdamikel/Speak-SID Speak&SID], [https://github.com/lambdamikel/LambdaSpeak3 LambdaSpeak], [https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/amsdap-amstrad-msx-adapter-connecting-any-msx-io-hardware-to-the-cpc/ Amsdap (SE-One, Moonsound, etc...)] are not supported by emulators

= Rewind feature =
ACE-DL has a rewind feature, but it is not as good as it could be: [https://youtu.be/wIKGvpnJLUo Demonstration of rewind in ACE-DL]

At the moment, only the RetroArch CPC emulator has a proper rewind feature: [https://youtu.be/YwilYlSe5LQ Demonstration of rewind in RetroArch]. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

A very simple approach would be to make a SNA for each frame and limit the RAM snapshot to 128KB, which is ok for 99% of CPC software. For a 10-seconds long rewind functionality, only 64MB RAM is needed (128KB * 50 frames * 10 seconds).

A more efficient approach is to store only the values that are changed in RAM between two frames, so that RAM can be restored when rewinding. This allows for long-rewinds, even of a CPC equipped with a 4MB RAM expansion. Proof of it is the GBA emulator [https://youtu.be/Sfc_1NKbiKg SkyEmu demonstrating super long rewind] while needing very few RAM.

For debugging, going back to the previous instruction is easily implemented. The emulator has to store the time when the previous instruction was executed so that he can go back to that instruction. In the same way, emulators can provide access to the previous HBL, IRQ, VBL, etc.

= Emulator Detection =

If you want to promote usage of real CPC computers, you can detect CPC emulators by:
*Checking if the memory is initialized with zeroes, as real machines have random memory values at boot
*Focusing on the minute details in Z80, CRTC and PPI chips. They are most often wrong in emulators
*Examining the FDC chip. It is only replicated more or less superficially in all emulators because the internals of the chip are still unknown

Combining these methods will definitely get you a 100% success rate in detecting emulators, even the toughest ones.

There is also this initiative for emulators who willingly want to be detected: [[Emulator_IDs|Emulator IDs]]

OffseT: /* SYMB */

= Snapshot (.SNA) file format =

The format was first defined for the [[CPCEMU|CPCEMU]] emulator but is now widely supported. The format was originally defined by [[Marco Vieth|Marco Vieth]]. Version 3 was defined by [[Ulrich Doewich|Ulrich Doewich]], [[Martin Korth|Martin Korth]], [[Richard Wilson|Richard Wilson]] and [[Kevin Thacker|Kevin Thacker]].

There are 3 versions defined in this document. Version 3 is the most recent and is currently supported by a few of the most recent emulators.

Snapshots produced with [[CPCE|CPCE]] appears to be the most compatible and will run correctly using any emulator.

Abbreviations:

*[[Gate Array|GA = "Gate Array"]]
*[[CRTC|CRTC = "6845 Cathode Ray Tube Controller"]]
*[[8255|PPI = "Intel 8255 Programmable Peripheral Interface"]]

== Notes ==

1. All multi-byte values are stored in little-endian format (low byte followed by higher bytes).

2. "IFF0" reflects the state of the maskable interrupt (INT). "IFF1" is used to store the state of IFF0 when a non-maskable interrupt (NMI) is executed. Bit 0 of these bytes is significant. For CPCEMU compatibility, these bytes should be set to "1" when the IFF flip-flop is "1" and "0" when the flip-flop is "0". For compatibility with other emulators, bits 7-1 should be set to "0". When bit 0 of "IFF0" is "0" maskable interrupts will be ignored. When bit 0 of "IFF1" is "1" maskable interrupts will be acknowledged and executed. See the document about the Z80 for more information.

3. This byte will be 0, 1 or 2 for the interrupt modes 0, 1 or 2. The interrupt mode is set using the "IM x" instructions. See the document about the Z80 for more information.

4. These registers are from the alternate register set of the Z80.

5. These registers are 16-bit. "low" indicates bits 7..0, "high"indicates bits 15..8.

6. This byte represents the inputs to PPI port A regardless of the input/output setting of this port.

7. This byte represents the inputs to PPI port B regardless of the input/output setting of this port.

8. This byte represents the outputs from port C regardless of the input/output setting of this port.

9. This byte represents the PPI control byte which defines the input/output and mode of each port and not the last value written to this port. For CPCEMU compatibility bit 7 of this byte must be set to "1".

10. This byte in the snapshot represents the selected pen register of the Gate-Array. This byte is the last value written to this port. Bit 7,6,5 should be set to "0".

11. This byte in the snapshot represents the multi-configuration register of the Gate-Array. This byte is the last byte written to this register. For CPCEMU compatibility, bit 7 should be set to "1" and bit 6 and bit 5 set to "0".

12. These bytes are the current palette. For CPCEMU compatibility, these bytes should have bit 7=bit 6=bit 5="0". Bits 4..0 define the colour using the hardware colour code. The colours are stored in the order pen 0, pen1, pen 2,...,pen 15 followed by border colour.

13. This byte represents a ram configuration for a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion, or the built in RAM expansion of the CPC6128 and CPC6128+. Bits 5..0 define the ram expansion code. For CPCEMU compatibility, bit 7 and bit 6 of this byte should be set to "0".

14. This byte in the snapshot represents the index of the currently selected CRTC register. For compatibility with CPCEMU this value should be in the range 0-31.

15. These bytes represent the data of the CRTC's registers.

16. This byte in the snapshot represents the last byte written to the "ROM select" I/O port.

17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.

18. the memory dump can have size 0 in version 3 and in this case all RAM is described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the main 64KB ram immediately followed by the second 64KB ram (if present) (this ram is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion. Note that CPCEMU can only write a 64K or 128K snapshot.

19. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. If standard CPC raster interrupts are used, interrupts are acknowledged and "executed" at the time they are requested, then there will be 6 interrupts executed per screen update cycle.

*CPCEMU uses a simple system to emulate the interrupts. It is assumed there are exactly 6 interrupts per screen update cycle (the interrupts are assumed to occur at a frequency of 300Hz). This byte records the interrupt number in the current screen update cycle. More accurate emulators use the correct interrupt generation method and may ignore this byte. For CPCEMU compatibility, these emulators should set this byte to "0".

*CPCEMU uses a simple system to emulate the screen display. It allows the mode to be changed in each of the 6 interrupts that occur during a single 50Hz/60Hz period. These bytes represent the mode in each of these sections, i.e. the screen modes (0,1 or 2) for the interrupts 0..5. More accurate emulators support changing of the screen mode at any point supported by the Amstrad hardware, these emulators should write "0" for all these bytes.

2. A version 2 snapshot describes Dk'Tronics/Dobbertin compatible RAM in addition to the 64KB base ram. This is a type of RAM expansion which uses the same port and paging mechanism as the extra 64KB inside the 6128. However, the RAM *MUST* be continuous, therefore it's limited to 64KB, 256KB or 512KB additional RAM. The Dk'Tronics silicon disk can't be described on it's own because it's RAM configurations do not start at C4.

The following configurations can be described:
* 64KB base + 64KB extra RAM (e.g. Dk'Tronics 64KB RAM Expansion)
* 64KB base + 256KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion)
* 64KB base + 512KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion & Dk'Tronics 256KB Silicon Disk OR X-MEM OR Symbiface 2 OR other device which provides 512KB)

JavaCPC uses this value to store up to 4MB of RAM. (e.g. [[CPC4MB]]). This type of ram is Dk'Tronics compatible and has multiple banks of 512KB. This value could be used to describe a 1MB or 2MB expansion as long as it is fully Dk'tronics compatible (e.g. rpalmer's 2MB).

== Notes ==

1. This byte in the snapshot represents the last byte written to the printer I/O port (this byte does not include the automatic inversion of the strobe caused by the Amstrad hardware).

2. This register is internal to the CRTC and counts the number of character-lines. The counter counts up. This value is in the range 0-127. (This counter is compared against CRTC register 4).

3. This register is internal to the CRTC and counts the number of raster-lines. The counter counts up. This value is in the range 0-31. (This counter is compared against CRTC register 9).

4. This register is internal to the CRTC and counts the number of raster-lines during vertical adjust. The counter counts up. This value is in the range 0-31. This should be ignored if the CRTC is not "executing" vertical. adjust.(This counter is compared against CRTC register 5).

5. This register is internal to the CRTC and counts the number of characters during horizontal sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" horizontal sync. (This counter is compared against CRTC register 3).

6. This register is internal to the CRTC and counts the number of scan-lines during vertical sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" vertical sync. (This counter is compared against CRTC register 3).

7. These bytes define the internal state of the CRTC. Each bit in these bytes represents a state.

8. When VSYNC is active, the CRTC is "executing" vertical sync, and the vertical sync width counter in the snapshot is used.

9. When HSYNC is active, the CRTC is "executing" horizontal sync width counter in the snapshot is used.

10. When Vertical total adjust is active, the CRTC is "executing" vertical total adjust and the vertical total adjust counter in the snapshot is used.

11. This register is internal to the CRTC and counts the number of characters. This counter counts up. This value is in the range 0-255. (This counter is compared against CRTC register 0).

12. This counter is internal to the GA and counts the number of HSYNCs. This counter is used to generate CPC raster interrupts. This counter counts up. This value is in the range 0-51.

13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).

14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active.

15. This is the current cylinder for each of 4 drives.

16. In WinAPE this counter is reset if a VSYNC occurs which causes the monitor to retrace vertically. This occurs if the VSYNC signal is active and this counter is greater than a threshold set by the V-Hold (normally 295 when V-Hold is 0), or if the counter reaches the maximum value (normally 351 when V-Hold is 0).

17. Since Plus emulation requires more information than simply whether an interrupt is active, this value (as used internally by WinAPE) contains:
* Bit 7 - Gate Array (or PRI) interrupt.
* Bit 6 - DMA Channel 0 interrupt.
* Bit 5 - DMA Channel 1 interrupt.
* Bit 4 - DMA Channel 2 interrupt.

It can be a combination of all or any interrupt sources. Interrupts are executed in the order raster, DMA 2, DMA 1, DMA 0.

Immediately following the memory dump there is optional data which is separated into chunks.

Each chunk of data has a header and this is followed by the data in the chunk. The header has the following format:

{|
|-
| ''Offset (Hex)''
| ''Count''
| ''Description''
|-
| 0
| 4
| Chunk name (note 1)
|-
| 4
| 4
| Chunk data length (note 2)
|}

Notes:

1. The chunks are defined with 4-byte character codes. (e.g. "CPC+"). In this example, the 4-byte character code would be stored in the file as 'C' then 'P' then 'C' then '+'.

2. The "Chunk data length" defines the length of data following the header and does not include the size of the header. This number is stored in little endian format.

3. If a emulator finds a chunk which it does not support then it should skip the chunk and continue with the next chunk in the file. Therefore an emulator author may add emulator specific chunks to the file and it will not prevent the snapshot from being used with other emulators that do not recognise the added chunks.

4. There is not a terminator chunk. The snapshot reader should determine if there are more chunks based on the size of data remaining to be read from the file.

=Version 3 Chunks=

The following chunks are currently defined:

== CPC+ ==

This chunk is supported by Arnold, WinAPE, No$CPC and ACE. Arnold, WinAPE and ACE will save the block when Plus configuration enabled. No$CPC will save the block if the Plus features have been unlocked.

When creating a snapshot with several chunks, it is usually a good idea to place the CPC+ one in first position, because some (old) tools and emulators are relying on this and will fail if it is not the case.

=== Notes ===

1. The sprite data is packed, with two sprite pixels per byte. Bits 7..4 define the first pixel and bits 3..0 define the second pixel.

2. The attributes for each sprite take 8 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| Sprite X (see note)

|}

Note: the Sprite X, Y and magnification are in the same order as the ASIC registers

3. This is a direct copy of the palette in CPC+ ASIC Ram. There are 32 colours each with 2-bytes per colour.

4. These bytes in the snapshot represent the last value written to these ASIC registers.

5. These bytes represent the inputs to the analogue channels.

6. The attributes for each DMA channel take 4 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| DMA Channel address (see note)
|-
| 2
| 1

|-
| 3

|}

Note: the DMA address and prescalar are in the same order as the ASIC registers.

7 These registers are internal to the CPC+ and define the current DMA operation:

|}

a. This value represents the number of loops remaining. 0 = none. This count is between 0..0FFF. This counter counts down.

b. This is the Amstrad memory address to loop back to. It is a pointer to the DMA instruction after the last REPEAT instruction.

c. This value represents the pause count and the count is between 0...0FFF. (TO BE CHECKED: down counter? what exactly does it represent)

d. This value represents the pause prescalar count and the count is between 0..FF. (TO BE CHECKED: down counter? what exactly does it represent)

8. This value represents the last value written to this I/O port. Winape uses 8a and not 8b. This value has bits 7,6,5 set to 1,0 and 1 respectively. 8b is in the original specification and is written by both ACE and No$CPC.

9. This value represents the lock status of RMR2. If locked, RMR2 can't be accessed otherwise it can.

10. This value represents the current unlock sequence state.

== DSCA,DSCB ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

The DSCA block contains the filename of the disc image inserted into drive A. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

DSCB is similar to DSCA but stores the filename of the disc image inserted into drive B.

== TAPE ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

The TAPE block contains the filename of the tape image inserted. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

== ROMS ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

This block contains a list of filenames for each ROM (and cartridge) that is defined. The length of the block is the length for all strings.

If a ROM is not defined, a single NUL (0) byte is present, otherwise there is a null terminated 8-bit ASCII string.

First in the list is the filename (or internal name) for the cartridge (prefixed with a 'A' character), followed by lower rom and then upper roms 0-31 (WinAPE) or 0-255 (ACE).

WinAPE lists internal ROMs by their internal name (the name listed in the drop down when you configure the roms, e.g. OS464).
ACE always put the actual file name, even for internal ROMs (e.g. System/Firmware_v3.rom).

After the list of the upper ROMs, ACE also put the names of the internal Basic and AMSDOS ROMs.
Then, the presence of the "CartridgeKeepExtROM" let ACE know if the cartridge ROMs should disable installed external upper ROMs or not (depending on user preferences).

NOTE: The selected Multiface ROM is not saved in the snapshot.

== INFO ==

This chunk is written by No$CPC. It contains an 8-bit ASCII string with the version information for No$CPC.

== MEM0-8 ==

The MEM0-8 chunks contain at most 64KB of data. The data may be compressed or stored uncompressed. If the size is exactly 65536 bytes the data is uncompressed, otherwise it is compressed. Up to 512KB additional RAM can be stored in a snapshot.

The compression scheme is RLE with 0x0e5 as the control byte.

Data is encoded as:

* <byte> for a single occurrence of a byte (not 0x0e5) (e.g. 0x013)
* 0x0e5,<count>,<byte> for multiple occurances of a byte (e. 0x0e5,0x04,0x013 for 0x013 repeated 4 times)
* 0x0e5,0 for a single 0x0e5 byte (e.g. 0x0e5)

The blocks are:

* MEM0 - main 64KB ram
* MEM1 - c4,c5,c6,c7 configurations (extra 64KB ram in 128KB machines) (256KB Dk'Tronics RAM, X-MEM)
* MEM2 - cc,cd,ce,cf configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM3 - d4,d5,d6,d7 configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM4 - dc,dd,de,df configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM5 - e4,e5,e6,e7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM6 - ec,ed,ee,ef configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM7 - f4,f5,f6,f7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM8 - fc,fd,fe,ff configurations (256KB Dk'Tronics Silicon Disk, X-MEM)

=== Notes ===

1. A snapshot may contain a mix of "standard" memory data (e.g. the data follows the header and is uncompressed) and additional MEM blocks as required.

2. If the snapshot is not compressed, then up to 128KB will be stored as "standard" memory data, the additional RAM stored in MEM2-MEM8 blocks.

3. If the snapshot is compressed, then the "standard" memory data will have 0 size and there will be a MEM0 in addition to the additional memory blocks.

4. Version 3 doesn't require memory to be continuous. A Dk'tronics silicon disk on it's own can be described with this version.

5. WinAPE allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.

6. ACE can save additional memory in snapshots (up to 4MB) using the MX?? chunks.

== MX09-40 ==

This chunk is supported by ACE.

MX?? chunks allow snapshots to store up to 4160KB ram.

MX?? chunks are following MEM0-8 chunks. They are numbered from 09 to 40 (hexadecimal numbering).
Information are stored compressed like in MEM0-8 chunks.

== BRKC ==

This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.
The number of stored breakpoints in the chunk is given by the chunk size divided by 216 (the size of one breakpoint data structure).

===Notes===

1. The condition is expressed using ACE syntax (similar to BASIC with AND/OR/XOR/NOT/+/-/=...).
Allowed additional syntaxes are:
*&, # or 0x for a hexadecimal number.
*% or &x for a binary number.
*AF, BC, HL, IX... for a 16-bit Z80 register.
*A, B, D, IXh, IXl... for an 8-bit Z80 register.
*FlagC, FlagNC, FlagM... for a Z80 flag.
*LineCount for the line number.
*LineCycle for the µs count on the current line.
*MemPage for the 64K expansion memory page (0-63).
*MemBankMode for the 16K expansion memory bank paging mode (0-7).
*UpperROMOn for the paging state of the upper ROM.
*UpperROMNum for the selected upper ROM number.
*LowerROMOn for the paging state of the lower ROM.
*LowerROMNum for the selected lower ROM number.
*ASICPageOn for the paging state of the I/O ASIC registers page.

''Example : FlagC AND (HL=DE OR HL=&5000)''

2. The map type determines the memory layout for which the breakpoint is valid.
The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).
* 1: Main RAM. If map bank is 0, then linear main RAM is considered. If map bank is 1, then main RAM from &c000-&ffff mapped as &4000-&7fff is considered. Map page is ignored (always 0).
* 2: Extension RAM. Map bank is the 16K extension bank number (0-3). Map page is the 64K extension page number (0-31).
* 3: Extension ROM. Map bank is the ROM slot id (0-255). Map page is ignored (always 0).
* 4: Firmware ROM. Map bank and page are ignored (always 0).
* 5: Cartridge ROM. Map bank is the 16K ROM bank number (0-31). Map page is ignored (always 0).
* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

== BRKS ==

This chunk is written by WinAPE when some breakpoints are set.
ACE can import breakpoints from this chunk but won't create it (BRKC is used instead).

The chunk contains 1 or more breakpoints.

Each breakpoint has the form:
* 2 bytes: address (LSB first)
* 1 byte: location (0: base 64K RAM, 1: extended RAM)
* 2 bytes: condition (?)

== WABP ==

This chunk is written by WinAPE when some breakpoints are set.
The exact details are begin worked out.

It seems to be:

4 bytes - number of user breakpoints

Each user breakpoint:

type,
4 byte address

Then, 4 bytes - number of memory breakpoints

Each memory breakpoint:

Then, 4 bytes - number of i/o breakpoints:

Each i/o breakpoint:

2 bytes flags? (6000 read, a400 write)
2 bytes port addr mask
2 bytes port addr
4 bytes counter
4 bytes condition string length, followed by condition string (not null terminated)

== DARS ==

This chunk is written by WinAPE when some data areas are set.

The number of stored data areas in the chunk is given by the chunk size divided by 10 (the size of one data area data structure).

=== Notes ===

1. Winape's addressing scheme is 4 bytes. The upper 16-bits effectively define the internal 64KB pages it uses.

== REMU ==

This chunk is written RASM and contains information about symbols and breakpoints.
ACE will import informations from this chunk but won't write it (SYMB and BRKC are used instead).

== RM00-FF ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

The RM00-FF chunks contain at most 16KB of data representing the contents of the related external upper ROMs number. The data may be compressed or stored uncompressed. If the size is exactly 16384 bytes the data is uncompressed, otherwise it is compressed. Up to 2MB of external upper ROMs can be stored in a snapshot.

The compression scheme is identical to the one from MEM0-7 chunks.

== LOWR ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal firmware ROM contents.

== BASR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal Basic ROM contents.

== DOSR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal AMSDOS ROM contents.

== CART ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It stores the contents of the inserted cartridge ROM. Extended cartridges are also supported.

== PLUG ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

This chunk stores the names of the plugins which should be enabled for the snapshot.

All names are stored one after the other, in the form of binary strings (first byte containing the plugin name length followed by the the actual string).
The names stored are the actual names of the plugins libraries (e.g. "multiface2.acepansion").

== Notes ==

1. All multi-byte values are stored in little-endian format (low byte followed by higher bytes).

2. "IFF0" reflects the state of the maskable interrupt (INT). "IFF1" is used to store the state of IFF0 when a non-maskable interrupt (NMI) is executed. Bit 0 of these bytes is significant. For CPCEMU compatibility, these bytes should be set to "1" when the IFF flip-flop is "1" and "0" when the flip-flop is "0". For compatibility with other emulators, bits 7-1 should be set to "0". When bit 0 of "IFF0" is "0" maskable interrupts will be ignored. When bit 0 of "IFF1" is "1" maskable interrupts will be acknowledged and executed. See the document about the Z80 for more information.

3. This byte will be 0, 1 or 2 for the interrupt modes 0, 1 or 2. The interrupt mode is set using the "IM x" instructions. See the document about the Z80 for more information.

4. These registers are from the alternate register set of the Z80.

5. These registers are 16-bit. "low" indicates bits 7..0, "high"indicates bits 15..8.

6. This byte represents the inputs to PPI port A regardless of the input/output setting of this port.

7. This byte represents the inputs to PPI port B regardless of the input/output setting of this port.

8. This byte represents the outputs from port C regardless of the input/output setting of this port.

9. This byte represents the PPI control byte which defines the input/output and mode of each port and not the last value written to this port. For CPCEMU compatibility bit 7 of this byte must be set to "1".

10. This byte in the snapshot represents the selected pen register of the Gate-Array. This byte is the last value written to this port. Bit 7,6,5 should be set to "0".

11. This byte in the snapshot represents the multi-configuration register of the Gate-Array. This byte is the last byte written to this register. For CPCEMU compatibility, bit 7 should be set to "1" and bit 6 and bit 5 set to "0".

12. These bytes are the current palette. For CPCEMU compatibility, these bytes should have bit 7=bit 6=bit 5="0". Bits 4..0 define the colour using the hardware colour code. The colours are stored in the order pen 0, pen1, pen 2,...,pen 15 followed by border colour.

13. This byte represents a ram configuration for a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion, or the built in RAM expansion of the CPC6128 and CPC6128+. Bits 5..0 define the ram expansion code. For CPCEMU compatibility, bit 7 and bit 6 of this byte should be set to "0".

14. This byte in the snapshot represents the index of the currently selected CRTC register. For compatibility with CPCEMU this value should be in the range 0-31.

15. These bytes represent the data of the CRTC's registers.

16. This byte in the snapshot represents the last byte written to the "ROM select" I/O port.

17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.

18. the memory dump can have size 0 in version 3 and in this case all RAM is described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the main 64KB ram immediately followed by the second 64KB ram (if present) (this ram is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion. Note that CPCEMU can only write a 64K or 128K snapshot.

19. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. If standard CPC raster interrupts are used, interrupts are acknowledged and "executed" at the time they are requested, then there will be 6 interrupts executed per screen update cycle.

*CPCEMU uses a simple system to emulate the interrupts. It is assumed there are exactly 6 interrupts per screen update cycle (the interrupts are assumed to occur at a frequency of 300Hz). This byte records the interrupt number in the current screen update cycle. More accurate emulators use the correct interrupt generation method and may ignore this byte. For CPCEMU compatibility, these emulators should set this byte to "0".

*CPCEMU uses a simple system to emulate the screen display. It allows the mode to be changed in each of the 6 interrupts that occur during a single 50Hz/60Hz period. These bytes represent the mode in each of these sections, i.e. the screen modes (0,1 or 2) for the interrupts 0..5. More accurate emulators support changing of the screen mode at any point supported by the Amstrad hardware, these emulators should write "0" for all these bytes.

2. A version 2 snapshot describes Dk'Tronics/Dobbertin compatible RAM in addition to the 64KB base ram. This is a type of RAM expansion which uses the same port and paging mechanism as the extra 64KB inside the 6128. However, the RAM *MUST* be continuous, therefore it's limited to 64KB, 256KB or 512KB additional RAM. The Dk'Tronics silicon disk can't be described on it's own because it's RAM configurations do not start at C4.

The following configurations can be described:
* 64KB base + 64KB extra RAM (e.g. Dk'Tronics 64KB RAM Expansion)
* 64KB base + 256KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion)
* 64KB base + 512KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion & Dk'Tronics 256KB Silicon Disk OR X-MEM OR Symbiface 2 OR other device which provides 512KB)

JavaCPC uses this value to store up to 4MB of RAM. (e.g. [[CPC4MB]]). This type of ram is Dk'Tronics compatible and has multiple banks of 512KB. This value could be used to describe a 1MB or 2MB expansion as long as it is fully Dk'tronics compatible (e.g. rpalmer's 2MB).

== Notes ==

1. This byte in the snapshot represents the last byte written to the printer I/O port (this byte does not include the automatic inversion of the strobe caused by the Amstrad hardware).

2. This register is internal to the CRTC and counts the number of character-lines. The counter counts up. This value is in the range 0-127. (This counter is compared against CRTC register 4).

3. This register is internal to the CRTC and counts the number of raster-lines. The counter counts up. This value is in the range 0-31. (This counter is compared against CRTC register 9).

4. This register is internal to the CRTC and counts the number of raster-lines during vertical adjust. The counter counts up. This value is in the range 0-31. This should be ignored if the CRTC is not "executing" vertical. adjust.(This counter is compared against CRTC register 5).

5. This register is internal to the CRTC and counts the number of characters during horizontal sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" horizontal sync. (This counter is compared against CRTC register 3).

6. This register is internal to the CRTC and counts the number of scan-lines during vertical sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" vertical sync. (This counter is compared against CRTC register 3).

7. These bytes define the internal state of the CRTC. Each bit in these bytes represents a state.

8. When VSYNC is active, the CRTC is "executing" vertical sync, and the vertical sync width counter in the snapshot is used.

9. When HSYNC is active, the CRTC is "executing" horizontal sync width counter in the snapshot is used.

10. When Vertical total adjust is active, the CRTC is "executing" vertical total adjust and the vertical total adjust counter in the snapshot is used.

11. This register is internal to the CRTC and counts the number of characters. This counter counts up. This value is in the range 0-255. (This counter is compared against CRTC register 0).

12. This counter is internal to the GA and counts the number of HSYNCs. This counter is used to generate CPC raster interrupts. This counter counts up. This value is in the range 0-51.

13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).

14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active.

15. This is the current cylinder for each of 4 drives.

16. In WinAPE this counter is reset if a VSYNC occurs which causes the monitor to retrace vertically. This occurs if the VSYNC signal is active and this counter is greater than a threshold set by the V-Hold (normally 295 when V-Hold is 0), or if the counter reaches the maximum value (normally 351 when V-Hold is 0).

17. Since Plus emulation requires more information than simply whether an interrupt is active, this value (as used internally by WinAPE) contains:
* Bit 7 - Gate Array (or PRI) interrupt.
* Bit 6 - DMA Channel 0 interrupt.
* Bit 5 - DMA Channel 1 interrupt.
* Bit 4 - DMA Channel 2 interrupt.

It can be a combination of all or any interrupt sources. Interrupts are executed in the order raster, DMA 2, DMA 1, DMA 0.

Immediately following the memory dump there is optional data which is separated into chunks.

Each chunk of data has a header and this is followed by the data in the chunk. The header has the following format:

{|
|-
| ''Offset (Hex)''
| ''Count''
| ''Description''
|-
| 0
| 4
| Chunk name (note 1)
|-
| 4
| 4
| Chunk data length (note 2)
|}

Notes:

1. The chunks are defined with 4-byte character codes. (e.g. "CPC+"). In this example, the 4-byte character code would be stored in the file as 'C' then 'P' then 'C' then '+'.

2. The "Chunk data length" defines the length of data following the header and does not include the size of the header. This number is stored in little endian format.

3. If a emulator finds a chunk which it does not support then it should skip the chunk and continue with the next chunk in the file. Therefore an emulator author may add emulator specific chunks to the file and it will not prevent the snapshot from being used with other emulators that do not recognise the added chunks.

4. There is not a terminator chunk. The snapshot reader should determine if there are more chunks based on the size of data remaining to be read from the file.

=Version 3 Chunks=

The following chunks are currently defined:

== CPC+ ==

This chunk is supported by Arnold, WinAPE, No$CPC and ACE. Arnold, WinAPE and ACE will save the block when Plus configuration enabled. No$CPC will save the block if the Plus features have been unlocked.

When creating a snapshot with several chunks, it is usually a good idea to place the CPC+ one in first position, because some (old) tools and emulators are relying on this and will fail if it is not the case.

=== Notes ===

1. The sprite data is packed, with two sprite pixels per byte. Bits 7..4 define the first pixel and bits 3..0 define the second pixel.

2. The attributes for each sprite take 8 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| Sprite X (see note)
|-
| 2
| 2
| Sprite Y (see note)
|-
| 4
| 1
| Sprite Magnification (see note)
|-
| 5-7
| 3
| unused (0)
|}

Note: the Sprite X, Y and magnification are in the same order as the ASIC registers

3. This is a direct copy of the palette in CPC+ ASIC Ram. There are 32 colours each with 2-bytes per colour.

4. These bytes in the snapshot represent the last value written to these ASIC registers.

5. These bytes represent the inputs to the analogue channels.

6. The attributes for each DMA channel take 4 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| DMA Channel address (see note)
|-
| 2
| 1
| DMA Channel prescalar (see note)
|-
| 3
| 1
| unused (0)
|}

Note: the DMA address and prescalar are in the same order as the ASIC registers.

7 These registers are internal to the CPC+ and define the current DMA operation:

| ''Length''
| ''Description''
|-
| 0
| 2
| loop counter (note a)
|-

| 2
| loop address (note b)
|-
| 4
| 2
| pause count (note c)
|-
| 6
| 1
| pause prescalar count (note d)
|}

a. This value represents the number of loops remaining. 0 = none. This count is between 0..0FFF. This counter counts down.

b. This is the Amstrad memory address to loop back to. It is a pointer to the DMA instruction after the last REPEAT instruction.

c. This value represents the pause count and the count is between 0...0FFF. (TO BE CHECKED: down counter? what exactly does it represent)

d. This value represents the pause prescalar count and the count is between 0..FF. (TO BE CHECKED: down counter? what exactly does it represent)

8. This value represents the last value written to this I/O port. Winape uses 8a and not 8b. This value has bits 7,6,5 set to 1,0 and 1 respectively. 8b is in the original specification and is written by both ACE and No$CPC.

9. This value represents the lock status of RMR2. If locked, RMR2 can't be accessed otherwise it can.

10. This value represents the current unlock sequence state.

{|
|-
| ''State ID''
| ''Synchronised State''
| ''Note''
|-
| 0
| Not synchronised
| ASIC is waiting for first non-zero byte to be written, this is the first synchronisation byte required
|-
| 1
| Not synchronised
| ASIC is waiting for zero byte to be written, this is the second synchronisation byte required
|-
| 2..10
| synchronised
| ASIC is waiting for byte from unlock sequence. e.g. if "2", ASIC is waiting for &FF, the first byte of the unlock sequence. if "3" ASIC is waiting for &77, the second byte of the unlock sequence.

== DSCA,DSCB ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

The DSCA block contains the filename of the disc image inserted into drive A. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

DSCB is similar to DSCA but stores the filename of the disc image inserted into drive B.

== TAPE ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

The TAPE block contains the filename of the tape image inserted. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

== ROMS ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

This block contains a list of filenames for each ROM (and cartridge) that is defined. The length of the block is the length for all strings.

If a ROM is not defined, a single NUL (0) byte is present, otherwise there is a null terminated 8-bit ASCII string.

First in the list is the filename (or internal name) for the cartridge (prefixed with a 'A' character), followed by lower rom and then upper roms 0-31 (WinAPE) or 0-255 (ACE).

WinAPE lists internal ROMs by their internal name (the name listed in the drop down when you configure the roms, e.g. OS464).
ACE always put the actual file name, even for internal ROMs (e.g. System/Firmware_v3.rom).

After the list of the upper ROMs, ACE also put the names of the internal Basic and AMSDOS ROMs.
Then, the presence of the "CartridgeKeepExtROM" let ACE know if the cartridge ROMs should disable installed external upper ROMs or not (depending on user preferences).

NOTE: The selected Multiface ROM is not saved in the snapshot.

== INFO ==

This chunk is written by No$CPC. It contains an 8-bit ASCII string with the version information for No$CPC.

== MEM0-8 ==

The MEM0-8 chunks contain at most 64KB of data. The data may be compressed or stored uncompressed. If the size is exactly 65536 bytes the data is uncompressed, otherwise it is compressed. Up to 512KB additional RAM can be stored in a snapshot.

The compression scheme is RLE with 0x0e5 as the control byte.

Data is encoded as:

* <byte> for a single occurrence of a byte (not 0x0e5) (e.g. 0x013)
* 0x0e5,<count>,<byte> for multiple occurances of a byte (e. 0x0e5,0x04,0x013 for 0x013 repeated 4 times)
* 0x0e5,0 for a single 0x0e5 byte (e.g. 0x0e5)

The blocks are:

* MEM0 - main 64KB ram
* MEM1 - c4,c5,c6,c7 configurations (extra 64KB ram in 128KB machines) (256KB Dk'Tronics RAM, X-MEM)
* MEM2 - cc,cd,ce,cf configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM3 - d4,d5,d6,d7 configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM4 - dc,dd,de,df configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM5 - e4,e5,e6,e7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM6 - ec,ed,ee,ef configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM7 - f4,f5,f6,f7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM8 - fc,fd,fe,ff configurations (256KB Dk'Tronics Silicon Disk, X-MEM)

=== Notes ===

1. A snapshot may contain a mix of "standard" memory data (e.g. the data follows the header and is uncompressed) and additional MEM blocks as required.

2. If the snapshot is not compressed, then up to 128KB will be stored as "standard" memory data, the additional RAM stored in MEM2-MEM8 blocks.

3. If the snapshot is compressed, then the "standard" memory data will have 0 size and there will be a MEM0 in addition to the additional memory blocks.

4. Version 3 doesn't require memory to be continuous. A Dk'tronics silicon disk on it's own can be described with this version.

5. WinAPE allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.

6. ACE can save additional memory in snapshots (up to 4MB) using the MX?? chunks.

== MX09-40 ==

This chunk is supported by ACE.

MX?? chunks allow snapshots to store up to 4160KB ram.

MX?? chunks are following MEM0-8 chunks. They are numbered from 09 to 40 (hexadecimal numbering).
Information are stored compressed like in MEM0-8 chunks.

== BRKC ==

This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.
The number of stored breakpoints in the chunk is given by the chunk size divided by 216 (the size of one breakpoint data structure).

===Notes===

1. The condition is expressed using ACE syntax (similar to BASIC with AND/OR/XOR/NOT/+/-/=...).
Allowed additional syntaxes are:
*&, # or 0x for a hexadecimal number.
*% or &x for a binary number.
*AF, BC, HL, IX... for a 16-bit Z80 register.
*A, B, D, IXh, IXl... for an 8-bit Z80 register.
*FlagC, FlagNC, FlagM... for a Z80 flag.
*LineCount for the line number.
*LineCycle for the µs count on the current line.
*MemPage for the 64K expansion memory page (0-63).
*MemBankMode for the 16K expansion memory bank paging mode (0-7).
*UpperROMOn for the paging state of the upper ROM.
*UpperROMNum for the selected upper ROM number.
*LowerROMOn for the paging state of the lower ROM.
*LowerROMNum for the selected lower ROM number.
*ASICPageOn for the paging state of the I/O ASIC registers page.

''Example : FlagC AND (HL=DE OR HL=&5000)''

2. The map type determines the memory layout for which the breakpoint is valid.
The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).
* 1: Main RAM. If map bank is 0, then linear main RAM is considered. If map bank is 1, then main RAM from &c000-&ffff mapped as &4000-&7fff is considered. Map page is ignored (always 0).
* 2: Extension RAM. Map bank is the 16K extension bank number (0-3). Map page is the 64K extension page number (0-31).
* 3: Extension ROM. Map bank is the ROM slot id (0-255). Map page is ignored (always 0).
* 4: Firmware ROM. Map bank and page are ignored (always 0).
* 5: Cartridge ROM. Map bank is the 16K ROM bank number (0-31). Map page is ignored (always 0).
* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

===Notes===

1. Symbol are (obviously) limited to 255 characters, cannot begin with a number (0-9), and only a limited set of ASCII char is allowed (a-z, A-Z, 0-9, _, .).
2. The map type determines the memory layout for which the symbol is valid. The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:

== BRKS ==

This chunk is written by WinAPE when some breakpoints are set.
ACE can import breakpoints from this chunk but won't create it (BRKC is used instead).

The chunk contains 1 or more breakpoints.

Each breakpoint has the form:
* 2 bytes: address (LSB first)
* 1 byte: location (0: base 64K RAM, 1: extended RAM)
* 2 bytes: condition (?)

== WABP ==

This chunk is written by WinAPE when some breakpoints are set.
The exact details are begin worked out.

It seems to be:

4 bytes - number of user breakpoints

Each user breakpoint:

type,
4 byte address

Then, 4 bytes - number of memory breakpoints

Each memory breakpoint:

Then, 4 bytes - number of i/o breakpoints:

Each i/o breakpoint:

2 bytes flags? (6000 read, a400 write)
2 bytes port addr mask
2 bytes port addr
4 bytes counter
4 bytes condition string length, followed by condition string (not null terminated)

== DARS ==

This chunk is written by WinAPE when some data areas are set.

The number of stored data areas in the chunk is given by the chunk size divided by 10 (the size of one data area data structure).

=== Notes ===

1. Winape's addressing scheme is 4 bytes. The upper 16-bits effectively define the internal 64KB pages it uses.

== REMU ==

This chunk is written RASM and contains information about symbols and breakpoints.
ACE will import informations from this chunk but won't write it (SYMB and BRKC are used instead).

== RM00-FF ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

The RM00-FF chunks contain at most 16KB of data representing the contents of the related external upper ROMs number. The data may be compressed or stored uncompressed. If the size is exactly 16384 bytes the data is uncompressed, otherwise it is compressed. Up to 2MB of external upper ROMs can be stored in a snapshot.

The compression scheme is identical to the one from MEM0-7 chunks.

== LOWR ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal firmware ROM contents.

== BASR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal Basic ROM contents.

== DOSR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal AMSDOS ROM contents.

== CART ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It stores the contents of the inserted cartridge ROM. Extended cartridges are also supported.

== PLUG ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

This chunk stores the names of the plugins which should be enabled for the snapshot.

All names are stored one after the other, in the form of binary strings (first byte containing the plugin name length followed by the the actual string).
The names stored are the actual names of the plugins libraries (e.g. "multiface2.acepansion").

== Notes ==

1. All multi-byte values are stored in little-endian format (low byte followed by higher bytes).

2. "IFF0" reflects the state of the maskable interrupt (INT). "IFF1" is used to store the state of IFF0 when a non-maskable interrupt (NMI) is executed. Bit 0 of these bytes is significant. For CPCEMU compatibility, these bytes should be set to "1" when the IFF flip-flop is "1" and "0" when the flip-flop is "0". For compatibility with other emulators, bits 7-1 should be set to "0". When bit 0 of "IFF0" is "0" maskable interrupts will be ignored. When bit 0 of "IFF1" is "1" maskable interrupts will be acknowledged and executed. See the document about the Z80 for more information.

3. This byte will be 0, 1 or 2 for the interrupt modes 0, 1 or 2. The interrupt mode is set using the "IM x" instructions. See the document about the Z80 for more information.

4. These registers are from the alternate register set of the Z80.

5. These registers are 16-bit. "low" indicates bits 7..0, "high"indicates bits 15..8.

6. This byte represents the inputs to PPI port A regardless of the input/output setting of this port.

7. This byte represents the inputs to PPI port B regardless of the input/output setting of this port.

8. This byte represents the outputs from port C regardless of the input/output setting of this port.

9. This byte represents the PPI control byte which defines the input/output and mode of each port and not the last value written to this port. For CPCEMU compatibility bit 7 of this byte must be set to "1".

10. This byte in the snapshot represents the selected pen register of the Gate-Array. This byte is the last value written to this port. Bit 7,6,5 should be set to "0".

11. This byte in the snapshot represents the multi-configuration register of the Gate-Array. This byte is the last byte written to this register. For CPCEMU compatibility, bit 7 should be set to "1" and bit 6 and bit 5 set to "0".

12. These bytes are the current palette. For CPCEMU compatibility, these bytes should have bit 7=bit 6=bit 5="0". Bits 4..0 define the colour using the hardware colour code. The colours are stored in the order pen 0, pen1, pen 2,...,pen 15 followed by border colour.

13. This byte represents a ram configuration for a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion, or the built in RAM expansion of the CPC6128 and CPC6128+. Bits 5..0 define the ram expansion code. For CPCEMU compatibility, bit 7 and bit 6 of this byte should be set to "0".

14. This byte in the snapshot represents the index of the currently selected CRTC register. For compatibility with CPCEMU this value should be in the range 0-31.

15. These bytes represent the data of the CRTC's registers.

16. This byte in the snapshot represents the last byte written to the "ROM select" I/O port.

17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.

18. the memory dump can have size 0 in version 3 and in this case all RAM is described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the main 64KB ram immediately followed by the second 64KB ram (if present) (this ram is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion. Note that CPCEMU can only write a 64K or 128K snapshot.

19. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. If standard CPC raster interrupts are used, interrupts are acknowledged and "executed" at the time they are requested, then there will be 6 interrupts executed per screen update cycle.

*CPCEMU uses a simple system to emulate the interrupts. It is assumed there are exactly 6 interrupts per screen update cycle (the interrupts are assumed to occur at a frequency of 300Hz). This byte records the interrupt number in the current screen update cycle. More accurate emulators use the correct interrupt generation method and may ignore this byte. For CPCEMU compatibility, these emulators should set this byte to "0".

*CPCEMU uses a simple system to emulate the screen display. It allows the mode to be changed in each of the 6 interrupts that occur during a single 50Hz/60Hz period. These bytes represent the mode in each of these sections, i.e. the screen modes (0,1 or 2) for the interrupts 0..5. More accurate emulators support changing of the screen mode at any point supported by the Amstrad hardware, these emulators should write "0" for all these bytes.

2. A version 2 snapshot describes Dk'Tronics/Dobbertin compatible RAM in addition to the 64KB base ram. This is a type of RAM expansion which uses the same port and paging mechanism as the extra 64KB inside the 6128. However, the RAM *MUST* be continuous, therefore it's limited to 64KB, 256KB or 512KB additional RAM. The Dk'Tronics silicon disk can't be described on it's own because it's RAM configurations do not start at C4.

The following configurations can be described:
* 64KB base + 64KB extra RAM (e.g. Dk'Tronics 64KB RAM Expansion)
* 64KB base + 256KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion)
* 64KB base + 512KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion & Dk'Tronics 256KB Silicon Disk OR X-MEM OR Symbiface 2 OR other device which provides 512KB)

JavaCPC uses this value to store up to 4MB of RAM. (e.g. [[CPC4MB]]). This type of ram is Dk'Tronics compatible and has multiple banks of 512KB. This value could be used to describe a 1MB or 2MB expansion as long as it is fully Dk'tronics compatible (e.g. rpalmer's 2MB).

== Notes ==

1. This byte in the snapshot represents the last byte written to the printer I/O port (this byte does not include the automatic inversion of the strobe caused by the Amstrad hardware).

2. This register is internal to the CRTC and counts the number of character-lines. The counter counts up. This value is in the range 0-127. (This counter is compared against CRTC register 4).

3. This register is internal to the CRTC and counts the number of raster-lines. The counter counts up. This value is in the range 0-31. (This counter is compared against CRTC register 9).

4. This register is internal to the CRTC and counts the number of raster-lines during vertical adjust. The counter counts up. This value is in the range 0-31. This should be ignored if the CRTC is not "executing" vertical. adjust.(This counter is compared against CRTC register 5).

5. This register is internal to the CRTC and counts the number of characters during horizontal sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" horizontal sync. (This counter is compared against CRTC register 3).

6. This register is internal to the CRTC and counts the number of scan-lines during vertical sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" vertical sync. (This counter is compared against CRTC register 3).

7. These bytes define the internal state of the CRTC. Each bit in these bytes represents a state.

8. When VSYNC is active, the CRTC is "executing" vertical sync, and the vertical sync width counter in the snapshot is used.

9. When HSYNC is active, the CRTC is "executing" horizontal sync width counter in the snapshot is used.

10. When Vertical total adjust is active, the CRTC is "executing" vertical total adjust and the vertical total adjust counter in the snapshot is used.

11. This register is internal to the CRTC and counts the number of characters. This counter counts up. This value is in the range 0-255. (This counter is compared against CRTC register 0).

12. This counter is internal to the GA and counts the number of HSYNCs. This counter is used to generate CPC raster interrupts. This counter counts up. This value is in the range 0-51.

13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).

14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active.

15. This is the current cylinder for each of 4 drives.

16. In WinAPE this counter is reset if a VSYNC occurs which causes the monitor to retrace vertically. This occurs if the VSYNC signal is active and this counter is greater than a threshold set by the V-Hold (normally 295 when V-Hold is 0), or if the counter reaches the maximum value (normally 351 when V-Hold is 0).

17. Since Plus emulation requires more information than simply whether an interrupt is active, this value (as used internally by WinAPE) contains:
* Bit 7 - Gate Array (or PRI) interrupt.
* Bit 6 - DMA Channel 0 interrupt.
* Bit 5 - DMA Channel 1 interrupt.
* Bit 4 - DMA Channel 2 interrupt.

It can be a combination of all or any interrupt sources. Interrupts are executed in the order raster, DMA 2, DMA 1, DMA 0.

Immediately following the memory dump there is optional data which is separated into chunks.

Each chunk of data has a header and this is followed by the data in the chunk. The header has the following format:

{|
|-
| ''Offset (Hex)''
| ''Count''
| ''Description''
|-
| 0
| 4
| Chunk name (note 1)
|-
| 4
| 4
| Chunk data length (note 2)
|}

Notes:

1. The chunks are defined with 4-byte character codes. (e.g. "CPC+"). In this example, the 4-byte character code would be stored in the file as 'C' then 'P' then 'C' then '+'.

2. The "Chunk data length" defines the length of data following the header and does not include the size of the header. This number is stored in little endian format.

3. If a emulator finds a chunk which it does not support then it should skip the chunk and continue with the next chunk in the file. Therefore an emulator author may add emulator specific chunks to the file and it will not prevent the snapshot from being used with other emulators that do not recognise the added chunks.

4. There is not a terminator chunk. The snapshot reader should determine if there are more chunks based on the size of data remaining to be read from the file.

=Version 3 Chunks=

The following chunks are currently defined:

== CPC+ ==

This chunk is supported by Arnold, WinAPE, No$CPC and ACE. Arnold, WinAPE and ACE will save the block when Plus configuration enabled. No$CPC will save the block if the Plus features have been unlocked.

When creating a snapshot with several chunks, it is usually a good idea to place the CPC+ one in first position, because some (old) tools and emulators are relying on this and will fail if it is not the case.

=== Notes ===

1. The sprite data is packed, with two sprite pixels per byte. Bits 7..4 define the first pixel and bits 3..0 define the second pixel.

2. The attributes for each sprite take 8 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| Sprite X (see note)

|}

Note: the Sprite X, Y and magnification are in the same order as the ASIC registers

3. This is a direct copy of the palette in CPC+ ASIC Ram. There are 32 colours each with 2-bytes per colour.

4. These bytes in the snapshot represent the last value written to these ASIC registers.

5. These bytes represent the inputs to the analogue channels.

6. The attributes for each DMA channel take 4 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| DMA Channel address (see note)
|-
| 2
| 1

|-
| 3

|}

Note: the DMA address and prescalar are in the same order as the ASIC registers.

7 These registers are internal to the CPC+ and define the current DMA operation:

|}

a. This value represents the number of loops remaining. 0 = none. This count is between 0..0FFF. This counter counts down.

b. This is the Amstrad memory address to loop back to. It is a pointer to the DMA instruction after the last REPEAT instruction.

c. This value represents the pause count and the count is between 0...0FFF. (TO BE CHECKED: down counter? what exactly does it represent)

d. This value represents the pause prescalar count and the count is between 0..FF. (TO BE CHECKED: down counter? what exactly does it represent)

8. This value represents the last value written to this I/O port. Winape uses 8a and not 8b. This value has bits 7,6,5 set to 1,0 and 1 respectively. 8b is in the original specification and is written by both ACE and No$CPC.

9. This value represents the lock status of RMR2. If locked, RMR2 can't be accessed otherwise it can.

10. This value represents the current unlock sequence state.

== DSCA,DSCB ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

The DSCA block contains the filename of the disc image inserted into drive A. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

DSCB is similar to DSCA but stores the filename of the disc image inserted into drive B.

== TAPE ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

The TAPE block contains the filename of the tape image inserted. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

== ROMS ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

This block contains a list of filenames for each ROM (and cartridge) that is defined. The length of the block is the length for all strings.

If a ROM is not defined, a single NUL (0) byte is present, otherwise there is a null terminated 8-bit ASCII string.

First in the list is the filename (or internal name) for the cartridge (prefixed with a 'A' character), followed by lower rom and then upper roms 0-31 (WinAPE) or 0-255 (ACE).

WinAPE lists internal ROMs by their internal name (the name listed in the drop down when you configure the roms, e.g. OS464).
ACE always put the actual file name, even for internal ROMs (e.g. System/Firmware_v3.rom).

After the list of the upper ROMs, ACE also put the names of the internal Basic and AMSDOS ROMs.
Then, the presence of the "CartridgeKeepExtROM" let ACE know if the cartridge ROMs should disable installed external upper ROMs or not (depending on user preferences).

NOTE: The selected Multiface ROM is not saved in the snapshot.

== INFO ==

This chunk is written by No$CPC. It contains an 8-bit ASCII string with the version information for No$CPC.

== MEM0-8 ==

The MEM0-8 chunks contain at most 64KB of data. The data may be compressed or stored uncompressed. If the size is exactly 65536 bytes the data is uncompressed, otherwise it is compressed. Up to 512KB additional RAM can be stored in a snapshot.

The compression scheme is RLE with 0x0e5 as the control byte.

Data is encoded as:

* <byte> for a single occurrence of a byte (not 0x0e5) (e.g. 0x013)
* 0x0e5,<count>,<byte> for multiple occurances of a byte (e. 0x0e5,0x04,0x013 for 0x013 repeated 4 times)
* 0x0e5,0 for a single 0x0e5 byte (e.g. 0x0e5)

The blocks are:

* MEM0 - main 64KB ram
* MEM1 - c4,c5,c6,c7 configurations (extra 64KB ram in 128KB machines) (256KB Dk'Tronics RAM, X-MEM)
* MEM2 - cc,cd,ce,cf configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM3 - d4,d5,d6,d7 configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM4 - dc,dd,de,df configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM5 - e4,e5,e6,e7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM6 - ec,ed,ee,ef configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM7 - f4,f5,f6,f7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM8 - fc,fd,fe,ff configurations (256KB Dk'Tronics Silicon Disk, X-MEM)

=== Notes ===

1. A snapshot may contain a mix of "standard" memory data (e.g. the data follows the header and is uncompressed) and additional MEM blocks as required.

2. If the snapshot is not compressed, then up to 128KB will be stored as "standard" memory data, the additional RAM stored in MEM2-MEM8 blocks.

3. If the snapshot is compressed, then the "standard" memory data will have 0 size and there will be a MEM0 in addition to the additional memory blocks.

4. Version 3 doesn't require memory to be continuous. A Dk'tronics silicon disk on it's own can be described with this version.

5. WinAPE allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.

6. ACE can save additional memory in snapshots (up to 4MB) using the MX?? chunks.

== MX09-40 ==

This chunk is supported by ACE.

MX?? chunks allow snapshots to store up to 4160KB ram.

MX?? chunks are following MEM0-8 chunks. They are numbered from 09 to 40 (hexadecimal numbering).
Information are stored compressed like in MEM0-8 chunks.

== BRKC ==

This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.
The number of stored breakpoints in the chunk is given by the chunk size divided by 216 (the size of one breakpoint data structure).

===Notes===

1. The condition is expressed using ACE syntax (similar to BASIC with AND/OR/XOR/NOT/+/-/=...).
Allowed additional syntaxes are:
*&, # or 0x for a hexadecimal number.
*% or &x for a binary number.
*AF, BC, HL, IX... for a 16-bit Z80 register.
*A, B, D, IXh, IXl... for an 8-bit Z80 register.
*FlagC, FlagNC, FlagM... for a Z80 flag.
*LineCount for the line number.
*LineCycle for the µs count on the current line.
*MemPage for the 64K expansion memory page (0-63).
*MemBankMode for the 16K expansion memory bank paging mode (0-7).
*UpperROMOn for the paging state of the upper ROM.
*UpperROMNum for the selected upper ROM number.
*LowerROMOn for the paging state of the lower ROM.
*LowerROMNum for the selected lower ROM number.
*ASICPageOn for the paging state of the I/O ASIC registers page.

''Example : FlagC AND (HL=DE OR HL=&5000)''

2. The map type determines the memory layout for which the breakpoint is valid.
The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).
* 1: Main RAM. If map bank is 0, then linear main RAM is considered. If map bank is 1, then main RAM from &c000-&ffff mapped as &4000-&7fff is considered. Map page is ignored (always 0).
* 2: Extension RAM. Map bank is the 16K extension bank number (0-3). Map page is the 64K extension page number (0-31).
* 3: Extension ROM. Map bank is the ROM slot id (0-255). Map page is ignored (always 0).
* 4: Firmware ROM. Map bank and page are ignored (always 0).
* 5: Cartridge ROM. Map bank is the 16K ROM bank number (0-31). Map page is ignored (always 0).
* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

===Notes===

1. Symbol are (obviously) limited to 255 characters, cannot begin with a number (0-9), and only a limited set of ASCII char is allowed (a-z, A-Z, 0-9, _).
2. The map type determines the memory layout for which the symbol is valid. The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).

== BRKS ==

This chunk is written by WinAPE when some breakpoints are set.
ACE can import breakpoints from this chunk but won't create it (BRKC is used instead).

The chunk contains 1 or more breakpoints.

Each breakpoint has the form:
* 2 bytes: address (LSB first)
* 1 byte: location (0: base 64K RAM, 1: extended RAM)
* 2 bytes: condition (?)

== WABP ==

This chunk is written by WinAPE when some breakpoints are set.
The exact details are begin worked out.

It seems to be:

4 bytes - number of user breakpoints

Each user breakpoint:

type,
4 byte address

Then, 4 bytes - number of memory breakpoints

Each memory breakpoint:

Then, 4 bytes - number of i/o breakpoints:

Each i/o breakpoint:

2 bytes flags? (6000 read, a400 write)
2 bytes port addr mask
2 bytes port addr
4 bytes counter
4 bytes condition string length, followed by condition string (not null terminated)

== DARS ==

This chunk is written by WinAPE when some data areas are set.

The number of stored data areas in the chunk is given by the chunk size divided by 10 (the size of one data area data structure).

=== Notes ===

1. Winape's addressing scheme is 4 bytes. The upper 16-bits effectively define the internal 64KB pages it uses.

== REMU ==

This chunk is written RASM and contains information about symbols and breakpoints.
ACE will import informations from this chunk but won't write it (SYMB and BRKC are used instead).

== RM00-FF ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

The RM00-FF chunks contain at most 16KB of data representing the contents of the related external upper ROMs number. The data may be compressed or stored uncompressed. If the size is exactly 16384 bytes the data is uncompressed, otherwise it is compressed. Up to 2MB of external upper ROMs can be stored in a snapshot.

The compression scheme is identical to the one from MEM0-7 chunks.

== LOWR ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal firmware ROM contents.

== BASR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal Basic ROM contents.

== DOSR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal AMSDOS ROM contents.

== CART ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It stores the contents of the inserted cartridge ROM. Extended cartridges are also supported.

== PLUG ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

This chunk stores the names of the plugins which should be enabled for the snapshot.

All names are stored one after the other, in the form of binary strings (first byte containing the plugin name length followed by the the actual string).
The names stored are the actual names of the plugins libraries (e.g. "multiface2.acepansion").

The format was first defined for the [[CPCEMU|CPCEMU]] emulator but is now widely supported. The format was originally defined by [[Marco Vieth|Marco Vieth]]. Version 3 was defined by [[Ulrich Doewich|Ulrich Doewich]], [[Martin Korth|Martin Korth]], [[Richard Wilson|Richard Wilson]] and [[Kevin Thacker|Kevin Thacker]].

There are 3 versions defined in this document. Version 3 is the most recent and is currently supported by a few of the most recent emulators.

Snapshots produced with [[CPCE|CPCE]] appears to be the most compatible and will run correctly using any emulator.

== Notes ==

1. All multi-byte values are stored in little-endian format (low byte followed by higher bytes).

2. "IFF0" reflects the state of the maskable interrupt (INT). "IFF1" is used to store the state of IFF0 when a non-maskable interrupt (NMI) is executed. Bit 0 of these bytes is significant. For CPCEMU compatibility, these bytes should be set to "1" when the IFF flip-flop is "1" and "0" when the flip-flop is "0". For compatibility with other emulators, bits 7-1 should be set to "0". When bit 0 of "IFF0" is "0" maskable interrupts will be ignored. When bit 0 of "IFF1" is "1" maskable interrupts will be acknowledged and executed. See the document about the Z80 for more information.

3. This byte will be 0, 1 or 2 for the interrupt modes 0, 1 or 2. The interrupt mode is set using the "IM x" instructions. See the document about the Z80 for more information.

4. These registers are from the alternate register set of the Z80.

5. These registers are 16-bit. "low" indicates bits 7..0, "high"indicates bits 15..8.

6. This byte represents the inputs to PPI port A regardless of the input/output setting of this port.

7. This byte represents the inputs to PPI port B regardless of the input/output setting of this port.

8. This byte represents the outputs from port C regardless of the input/output setting of this port.

9. This byte represents the PPI control byte which defines the input/output and mode of each port and not the last value written to this port. For CPCEMU compatibility bit 7 of this byte must be set to "1".

10. This byte in the snapshot represents the selected pen register of the Gate-Array. This byte is the last value written to this port. Bit 7,6,5 should be set to "0".

11. This byte in the snapshot represents the multi-configuration register of the Gate-Array. This byte is the last byte written to this register. For CPCEMU compatibility, bit 7 should be set to "1" and bit 6 and bit 5 set to "0".

12. These bytes are the current palette. For CPCEMU compatibility, these bytes should have bit 7=bit 6=bit 5="0". Bits 4..0 define the colour using the hardware colour code. The colours are stored in the order pen 0, pen1, pen 2,...,pen 15 followed by border colour.

13. This byte represents a ram configuration for a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion, or the built in RAM expansion of the CPC6128 and CPC6128+. Bits 5..0 define the ram expansion code. For CPCEMU compatibility, bit 7 and bit 6 of this byte should be set to "0".

14. This byte in the snapshot represents the index of the currently selected CRTC register. For compatibility with CPCEMU this value should be in the range 0-31.

15. These bytes represent the data of the CRTC's registers.

16. This byte in the snapshot represents the last byte written to the "ROM select" I/O port.

17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.

18. the memory dump can have size 0 in version 3 and in this case all RAM is described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the main 64KB ram immediately followed by the second 64KB ram (if present) (this ram is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion. Note that CPCEMU can only write a 64K or 128K snapshot.

19. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. If standard CPC raster interrupts are used, interrupts are acknowledged and "executed" at the time they are requested, then there will be 6 interrupts executed per screen update cycle.

*CPCEMU uses a simple system to emulate the interrupts. It is assumed there are exactly 6 interrupts per screen update cycle (the interrupts are assumed to occur at a frequency of 300Hz). This byte records the interrupt number in the current screen update cycle. More accurate emulators use the correct interrupt generation method and may ignore this byte. For CPCEMU compatibility, these emulators should set this byte to "0".

*CPCEMU uses a simple system to emulate the screen display. It allows the mode to be changed in each of the 6 interrupts that occur during a single 50Hz/60Hz period. These bytes represent the mode in each of these sections, i.e. the screen modes (0,1 or 2) for the interrupts 0..5. More accurate emulators support changing of the screen mode at any point supported by the Amstrad hardware, these emulators should write "0" for all these bytes.

2. A version 2 snapshot describes Dk'Tronics/Dobbertin compatible RAM in addition to the 64KB base ram. This is a type of RAM expansion which uses the same port and paging mechanism as the extra 64KB inside the 6128. However, the RAM *MUST* be continuous, therefore it's limited to 64KB, 256KB or 512KB additional RAM. The Dk'Tronics silicon disk can't be described on it's own because it's RAM configurations do not start at C4.

The following configurations can be described:
* 64KB base + 64KB extra RAM (e.g. Dk'Tronics 64KB RAM Expansion)
* 64KB base + 256KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion)
* 64KB base + 512KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion & Dk'Tronics 256KB Silicon Disk OR X-MEM OR Symbiface 2 OR other device which provides 512KB)

JavaCPC uses this value to store up to 4MB of RAM. (e.g. [[CPC4MB]]). This type of ram is Dk'Tronics compatible and has multiple banks of 512KB. This value could be used to describe a 1MB or 2MB expansion as long as it is fully Dk'tronics compatible (e.g. rpalmer's 2MB).

== Notes ==

1. This byte in the snapshot represents the last byte written to the printer I/O port (this byte does not include the automatic inversion of the strobe caused by the Amstrad hardware).

2. This register is internal to the CRTC and counts the number of character-lines. The counter counts up. This value is in the range 0-127. (This counter is compared against CRTC register 4).

3. This register is internal to the CRTC and counts the number of raster-lines. The counter counts up. This value is in the range 0-31. (This counter is compared against CRTC register 9).

4. This register is internal to the CRTC and counts the number of raster-lines during vertical adjust. The counter counts up. This value is in the range 0-31. This should be ignored if the CRTC is not "executing" vertical. adjust.(This counter is compared against CRTC register 5).

5. This register is internal to the CRTC and counts the number of characters during horizontal sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" horizontal sync. (This counter is compared against CRTC register 3).

6. This register is internal to the CRTC and counts the number of scan-lines during vertical sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" vertical sync. (This counter is compared against CRTC register 3).

7. These bytes define the internal state of the CRTC. Each bit in these bytes represents a state.

8. When VSYNC is active, the CRTC is "executing" vertical sync, and the vertical sync width counter in the snapshot is used.

9. When HSYNC is active, the CRTC is "executing" horizontal sync width counter in the snapshot is used.

10. When Vertical total adjust is active, the CRTC is "executing" vertical total adjust and the vertical total adjust counter in the snapshot is used.

11. This register is internal to the CRTC and counts the number of characters. This counter counts up. This value is in the range 0-255. (This counter is compared against CRTC register 0).

12. This counter is internal to the GA and counts the number of HSYNCs. This counter is used to generate CPC raster interrupts. This counter counts up. This value is in the range 0-51.

13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).

14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active.

15. This is the current cylinder for each of 4 drives.

16. In WinAPE this counter is reset if a VSYNC occurs which causes the monitor to retrace vertically. This occurs if the VSYNC signal is active and this counter is greater than a threshold set by the V-Hold (normally 295 when V-Hold is 0), or if the counter reaches the maximum value (normally 351 when V-Hold is 0).

17. Since Plus emulation requires more information than simply whether an interrupt is active, this value (as used internally by WinAPE) contains:
* Bit 7 - Gate Array (or PRI) interrupt.
* Bit 6 - DMA Channel 0 interrupt.
* Bit 5 - DMA Channel 1 interrupt.
* Bit 4 - DMA Channel 2 interrupt.

It can be a combination of all or any interrupt sources. Interrupts are executed in the order raster, DMA 2, DMA 1, DMA 0.

Immediately following the memory dump there is optional data which is separated into chunks.

Each chunk of data has a header and this is followed by the data in the chunk. The header has the following format:

{|

Notes:

1. The chunks are defined with 4-byte character codes. (e.g. "CPC+"). In this example, the 4-byte character code would be stored in the file as 'C' then 'P' then 'C' then '+'.

2. The "Chunk data length" defines the length of data following the header and does not include the size of the header. This number is stored in little endian format.

3. If a emulator finds a chunk which it does not support then it should skip the chunk and continue with the next chunk in the file. Therefore an emulator author may add emulator specific chunks to the file and it will not prevent the snapshot from being used with other emulators that do not recognise the added chunks.

4. There is not a terminator chunk. The snapshot reader should determine if there are more chunks based on the size of data remaining to be read from the file.

=Version 3 Chunks=

The following chunks are currently defined:

== CPC+ ==

This chunk is supported by Arnold, WinAPE, No$CPC and ACE. Arnold, WinAPE and ACE will save the block when Plus configuration enabled. No$CPC will save the block if the Plus features have been unlocked.

When creating a snapshot with several chunks, it is usually a good idea to place the CPC+ one in first position, because some (old) tools and emulators are relying on this and will fail if it is not the case.

=== Notes ===

1. The sprite data is packed, with two sprite pixels per byte. Bits 7..4 define the first pixel and bits 3..0 define the second pixel.

2. The attributes for each sprite take 8 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| Sprite X (see note)
|-
| 2
| 2
| Sprite Y (see note)
|-
| 4
| 1
| Sprite Magnification (see note)
|-
| 5-7
| 3
| unused (0)
|}

Note: the Sprite X, Y and magnification are in the same order as the ASIC registers

3. This is a direct copy of the palette in CPC+ ASIC Ram. There are 32 colours each with 2-bytes per colour.

4. These bytes in the snapshot represent the last value written to these ASIC registers.

5. These bytes represent the inputs to the analogue channels.

6. The attributes for each DMA channel take 4 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| DMA Channel address (see note)
|-
| 2
| 1
| DMA Channel prescalar (see note)
|-
| 3
| 1
| unused (0)
|}

Note: the DMA address and prescalar are in the same order as the ASIC registers.

7 These registers are internal to the CPC+ and define the current DMA operation:

| loop address (note b)
|-
| 4
| 2
| pause count (note c)
|-
| 6

| pause prescalar count (note d)
|}

a. This value represents the number of loops remaining. 0 = none. This count is between 0..0FFF. This counter counts down.

b. This is the Amstrad memory address to loop back to. It is a pointer to the DMA instruction after the last REPEAT instruction.

c. This value represents the pause count and the count is between 0...0FFF. (TO BE CHECKED: down counter? what exactly does it represent)

d. This value represents the pause prescalar count and the count is between 0..FF. (TO BE CHECKED: down counter? what exactly does it represent)

8. This value represents the last value written to this I/O port. Winape uses 8a and not 8b. This value has bits 7,6,5 set to 1,0 and 1 respectively. 8b is in the original specification and is written by both ACE and No$CPC.

9. This value represents the lock status of RMR2. If locked, RMR2 can't be accessed otherwise it can.

10. This value represents the current unlock sequence state.

== DSCA,DSCB ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

The DSCA block contains the filename of the disc image inserted into drive A. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

DSCB is similar to DSCA but stores the filename of the disc image inserted into drive B.

== TAPE ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

The TAPE block contains the filename of the tape image inserted. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

== ROMS ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

This block contains a list of filenames for each ROM (and cartridge) that is defined. The length of the block is the length for all strings.

If a ROM is not defined, a single NUL (0) byte is present, otherwise there is a null terminated 8-bit ASCII string.

First in the list is the filename (or internal name) for the cartridge (prefixed with a 'A' character), followed by lower rom and then upper roms 0-31 (WinAPE) or 0-255 (ACE).

WinAPE lists internal ROMs by their internal name (the name listed in the drop down when you configure the roms, e.g. OS464).
ACE always put the actual file name, even for internal ROMs (e.g. System/Firmware_v3.rom).

After the list of the upper ROMs, ACE also put the names of the internal Basic and AMSDOS ROMs.
Then, the presence of the "CartridgeKeepExtROM" let ACE know if the cartridge ROMs should disable installed external upper ROMs or not (depending on user preferences).

NOTE: The selected Multiface ROM is not saved in the snapshot.

== INFO ==

This chunk is written by No$CPC. It contains an 8-bit ASCII string with the version information for No$CPC.

== MEM0-8 ==

The MEM0-8 chunks contain at most 64KB of data. The data may be compressed or stored uncompressed. If the size is exactly 65536 bytes the data is uncompressed, otherwise it is compressed. Up to 512KB additional RAM can be stored in a snapshot.

The compression scheme is RLE with 0x0e5 as the control byte.

Data is encoded as:

* <byte> for a single occurrence of a byte (not 0x0e5) (e.g. 0x013)
* 0x0e5,<count>,<byte> for multiple occurances of a byte (e. 0x0e5,0x04,0x013 for 0x013 repeated 4 times)
* 0x0e5,0 for a single 0x0e5 byte (e.g. 0x0e5)

The blocks are:

* MEM0 - main 64KB ram
* MEM1 - c4,c5,c6,c7 configurations (extra 64KB ram in 128KB machines) (256KB Dk'Tronics RAM, X-MEM)
* MEM2 - cc,cd,ce,cf configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM3 - d4,d5,d6,d7 configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM4 - dc,dd,de,df configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM5 - e4,e5,e6,e7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM6 - ec,ed,ee,ef configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM7 - f4,f5,f6,f7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM8 - fc,fd,fe,ff configurations (256KB Dk'Tronics Silicon Disk, X-MEM)

=== Notes ===

1. A snapshot may contain a mix of "standard" memory data (e.g. the data follows the header and is uncompressed) and additional MEM blocks as required.

2. If the snapshot is not compressed, then up to 128KB will be stored as "standard" memory data, the additional RAM stored in MEM2-MEM8 blocks.

3. If the snapshot is compressed, then the "standard" memory data will have 0 size and there will be a MEM0 in addition to the additional memory blocks.

4. Version 3 doesn't require memory to be continuous. A Dk'tronics silicon disk on it's own can be described with this version.

5. WinAPE allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.

6. ACE can save additional memory in snapshots (up to 4MB) using the MX?? chunks.

== MX09-40 ==

This chunk is supported by ACE.

MX?? chunks allow snapshots to store up to 4160KB ram.

MX?? chunks are following MEM0-8 chunks. They are numbered from 09 to 40 (hexadecimal numbering).
Information are stored compressed like in MEM0-8 chunks.

== BRKC ==

This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.
The number of stored breakpoints in the chunk is given by the chunk size divided by 216 (the size on one breakpoint data structure).

===Notes===

1. The condition is expressed using ACE syntax (similar to BASIC with AND/OR/XOR/NOT/+/-/=...).
Allowed additional syntaxes are:
*&, # or 0x for a hexadecimal number.
*% or &x for a binary number.
*AF, BC, HL, IX... for a 16-bit Z80 register.
*A, B, D, IXh, IXl... for an 8-bit Z80 register.
*FlagC, FlagNC, FlagM... for a Z80 flag.
*LineCount for the line number.
*LineCycle for the µs count on the current line.
*MemPage for the 64K expansion memory page (0-63).
*MemBankMode for the 16K expansion memory bank paging mode (0-7).
*UpperROMOn for the paging state of the upper ROM.
*UpperROMNum for the selected upper ROM number.
*LowerROMOn for the paging state of the lower ROM.
*LowerROMNum for the selected lower ROM number.
*ASICPageOn for the paging state of the I/O ASIC registers page.

''Example : FlagC AND (HL=DE OR HL=&5000)''

2. The map type determines the memory layout for which the breakpoint is valid.
The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).
* 1: Main RAM. If map bank is 0, then linear main RAM is considered. If map bank is 1, then main RAM from &c000-&ffff mapped as &4000-&7fff is considered. Map page is ignored (always 0).
* 2: Extension RAM. Map bank is the 16K extension bank number (0-3). Map page is the 64K extension page number (0-31).
* 3: Extension ROM. Map bank is the ROM slot id (0-255). Map page is ignored (always 0).
* 4: Firmware ROM. Map bank and page are ignored (always 0).
* 5: Cartridge ROM. Map bank is the 16K ROM bank number (0-31). Map page is ignored (always 0).
* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

===Notes===

1. Symbol are (obviously) limited to 255 characters, cannot begin with a number (0-9), and only a limited set of ASCII char is allowed (a-z, A-Z, 0-9, _).
2. The map type determines the memory layout for which the symbol is valid. The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).

* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

== BRKS ==

This chunk is written by WinAPE when some breakpoints are set.
ACE can import breakpoints from this chunk but won't create it (BRKC is used instead).

The chunk contains 1 or more breakpoints.

Each breakpoint has the form:
* 2 bytes: address (LSB first)
* 1 byte: location (0: base 64K RAM, 1: extended RAM)
* 2 bytes: condition (?)

== WABP ==

This chunk is written by WinAPE when some breakpoints are set.
The exact details are begin worked out.

It seems to be:

4 bytes - number of user breakpoints

Each user breakpoint:

type,
4 byte address

Then, 4 bytes - number of memory breakpoints

Each memory breakpoint:

Then, 4 bytes - number of i/o breakpoints:

Each i/o breakpoint:

2 bytes flags? (6000 read, a400 write)
2 bytes port addr mask
2 bytes port addr
4 bytes counter
4 bytes condition string length, followed by condition string (not null terminated)

== DARS ==

This chunk is written by WinAPE when some data areas are set.

The number of stored data areas in the chunk is given by the chunk size divided by 10 (the size of one data area data structure).

=== Notes ===

1. Winape's addressing scheme is 4 bytes. The upper 16-bits effectively define the internal 64KB pages it uses.

== REMU ==

This chunk is written RASM and contains information about symbols and breakpoints.
ACE will import informations from this chunk but won't write it (SYMB and BRKC are used instead).

== RM00-FF ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

The RM00-FF chunks contain at most 16KB of data representing the contents of the related external upper ROMs number. The data may be compressed or stored uncompressed. If the size is exactly 16384 bytes the data is uncompressed, otherwise it is compressed. Up to 2MB of external upper ROMs can be stored in a snapshot.

The compression scheme is identical to the one from MEM0-7 chunks.

== LOWR ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal firmware ROM contents.

== BASR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal Basic ROM contents.

== DOSR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal AMSDOS ROM contents.

== CART ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It stores the contents of the inserted cartridge ROM. Extended cartridges are also supported.

== PLUG ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

This chunk stores the names of the plugins which should be enabled for the snapshot.

All names are stored one after the other, in the form of binary strings (first byte containing the plugin name length followed by the the actual string).
The names stored are the actual names of the plugins libraries (e.g. "multiface2.acepansion").

2. "IFF0" reflects the state of the maskable interrupt (INT). "IFF1" is used to store the state of IFF0 when a non-maskable interrupt (NMI) is executed. Bit 0 of these bytes is significant. For CPCEMU compatibility, these bytes should be set to "1" when the IFF flip-flop is "1" and "0" when the flip-flop is "0". For compatibility with other emulators, bits 7-1 should be set to "0". When bit 0 of "IFF0" is "0" maskable interrupts will be ignored. When bit 0 of "IFF1" is "1" maskable interrupts will be acknowledged and executed. See the document about the Z80 for more information.

3. This byte will be 0, 1 or 2 for the interrupt modes 0, 1 or 2. The interrupt mode is set using the "IM x" instructions. See the document about the Z80 for more information.

4. These registers are from the alternate register set of the Z80.

5. These registers are 16-bit. "low" indicates bits 7..0, "high"indicates bits 15..8.

6. This byte represents the inputs to PPI port A regardless of the input/output setting of this port.

7. This byte represents the inputs to PPI port B regardless of the input/output setting of this port.

8. This byte represents the outputs from port C regardless of the input/output setting of this port.

9. This byte represents the PPI control byte which defines the input/output and mode of each port and not the last value written to this port. For CPCEMU compatibility bit 7 of this byte must be set to "1".

10. This byte in the snapshot represents the selected pen register of the Gate-Array. This byte is the last value written to this port. Bit 7,6,5 should be set to "0".

11. This byte in the snapshot represents the multi-configuration register of the Gate-Array. This byte is the last byte written to this register. For CPCEMU compatibility, bit 7 should be set to "1" and bit 6 and bit 5 set to "0".

12. These bytes are the current palette. For CPCEMU compatibility, these bytes should have bit 7=bit 6=bit 5="0". Bits 4..0 define the colour using the hardware colour code. The colours are stored in the order pen 0, pen1, pen 2,...,pen 15 followed by border colour.

13. This byte represents a ram configuration for a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion, or the built in RAM expansion of the CPC6128 and CPC6128+. Bits 5..0 define the ram expansion code. For CPCEMU compatibility, bit 7 and bit 6 of this byte should be set to "0".

14. This byte in the snapshot represents the index of the currently selected CRTC register. For compatibility with CPCEMU this value should be in the range 0-31.

15. These bytes represent the data of the CRTC's registers.

16. This byte in the snapshot represents the last byte written to the "ROM select" I/O port.

17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.

18. the memory dump can have size 0 in version 3 and in this case all RAM is described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the main 64KB ram immediately followed by the second 64KB ram (if present) (this ram is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion. Note that CPCEMU can only write a 64K or 128K snapshot.

19. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. If standard CPC raster interrupts are used, interrupts are acknowledged and "executed" at the time they are requested, then there will be 6 interrupts executed per screen update cycle.

*CPCEMU uses a simple system to emulate the interrupts. It is assumed there are exactly 6 interrupts per screen update cycle (the interrupts are assumed to occur at a frequency of 300Hz). This byte records the interrupt number in the current screen update cycle. More accurate emulators use the correct interrupt generation method and may ignore this byte. For CPCEMU compatibility, these emulators should set this byte to "0".

*CPCEMU uses a simple system to emulate the screen display. It allows the mode to be changed in each of the 6 interrupts that occur during a single 50Hz/60Hz period. These bytes represent the mode in each of these sections, i.e. the screen modes (0,1 or 2) for the interrupts 0..5. More accurate emulators support changing of the screen mode at any point supported by the Amstrad hardware, these emulators should write "0" for all these bytes.

2. A version 2 snapshot describes Dk'Tronics/Dobbertin compatible RAM in addition to the 64KB base ram. This is a type of RAM expansion which uses the same port and paging mechanism as the extra 64KB inside the 6128. However, the RAM *MUST* be continuous, therefore it's limited to 64KB, 256KB or 512KB additional RAM. The Dk'Tronics silicon disk can't be described on it's own because it's RAM configurations do not start at C4.

The following configurations can be described:
* 64KB base + 64KB extra RAM (e.g. Dk'Tronics 64KB RAM Expansion)
* 64KB base + 256KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion)
* 64KB base + 512KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion & Dk'Tronics 256KB Silicon Disk OR X-MEM OR Symbiface 2 OR other device which provides 512KB)

JavaCPC uses this value to store up to 4MB of RAM. (e.g. [[CPC4MB]]). This type of ram is Dk'Tronics compatible and has multiple banks of 512KB. This value could be used to describe a 1MB or 2MB expansion as long as it is fully Dk'tronics compatible (e.g. rpalmer's 2MB).

== Notes ==

1. This byte in the snapshot represents the last byte written to the printer I/O port (this byte does not include the automatic inversion of the strobe caused by the Amstrad hardware).

2. This register is internal to the CRTC and counts the number of character-lines. The counter counts up. This value is in the range 0-127. (This counter is compared against CRTC register 4).

3. This register is internal to the CRTC and counts the number of raster-lines. The counter counts up. This value is in the range 0-31. (This counter is compared against CRTC register 9).

4. This register is internal to the CRTC and counts the number of raster-lines during vertical adjust. The counter counts up. This value is in the range 0-31. This should be ignored if the CRTC is not "executing" vertical. adjust.(This counter is compared against CRTC register 5).

5. This register is internal to the CRTC and counts the number of characters during horizontal sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" horizontal sync. (This counter is compared against CRTC register 3).

6. This register is internal to the CRTC and counts the number of scan-lines during vertical sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" vertical sync. (This counter is compared against CRTC register 3).

7. These bytes define the internal state of the CRTC. Each bit in these bytes represents a state.

8. When VSYNC is active, the CRTC is "executing" vertical sync, and the vertical sync width counter in the snapshot is used.

9. When HSYNC is active, the CRTC is "executing" horizontal sync width counter in the snapshot is used.

10. When Vertical total adjust is active, the CRTC is "executing" vertical total adjust and the vertical total adjust counter in the snapshot is used.

11. This register is internal to the CRTC and counts the number of characters. This counter counts up. This value is in the range 0-255. (This counter is compared against CRTC register 0).

12. This counter is internal to the GA and counts the number of HSYNCs. This counter is used to generate CPC raster interrupts. This counter counts up. This value is in the range 0-51.

13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).

14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active.

15. This is the current cylinder for each of 4 drives.

16. In WinAPE this counter is reset if a VSYNC occurs which causes the monitor to retrace vertically. This occurs if the VSYNC signal is active and this counter is greater than a threshold set by the V-Hold (normally 295 when V-Hold is 0), or if the counter reaches the maximum value (normally 351 when V-Hold is 0).

17. Since Plus emulation requires more information than simply whether an interrupt is active, this value (as used internally by WinAPE) contains:
* Bit 7 - Gate Array (or PRI) interrupt.
* Bit 6 - DMA Channel 0 interrupt.
* Bit 5 - DMA Channel 1 interrupt.
* Bit 4 - DMA Channel 2 interrupt.

It can be a combination of all or any interrupt sources. Interrupts are executed in the order raster, DMA 2, DMA 1, DMA 0.

Immediately following the memory dump there is optional data which is separated into chunks.

Each chunk of data has a header and this is followed by the data in the chunk. The header has the following format:

{|
|-
| ''Offset (Hex)''
| ''Count''
| ''Description''
|-
| 0
| 4
| Chunk name (note 1)
|-
| 4
| 4
| Chunk data length (note 2)
|}

Notes:

1. The chunks are defined with 4-byte character codes. (e.g. "CPC+"). In this example, the 4-byte character code would be stored in the file as 'C' then 'P' then 'C' then '+'.

2. The "Chunk data length" defines the length of data following the header and does not include the size of the header. This number is stored in little endian format.

3. If a emulator finds a chunk which it does not support then it should skip the chunk and continue with the next chunk in the file. Therefore an emulator author may add emulator specific chunks to the file and it will not prevent the snapshot from being used with other emulators that do not recognise the added chunks.

4. There is not a terminator chunk. The snapshot reader should determine if there are more chunks based on the size of data remaining to be read from the file.

=Version 3 Chunks=

The following chunks are currently defined:

== CPC+ ==

This chunk is supported by Arnold, WinAPE, No$CPC and ACE. Arnold, WinAPE and ACE will save the block when Plus configuration enabled. No$CPC will save the block if the Plus features have been unlocked.

When creating a snapshot with several chunks, it is usually a good idea to place the CPC+ one in first position, because some (old) tools and emulators are relying on this.

=== Notes ===

1. The sprite data is packed, with two sprite pixels per byte. Bits 7..4 define the first pixel and bits 3..0 define the second pixel.

2. The attributes for each sprite take 8 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| Sprite X (see note)
|-

| Sprite Magnification (see note)
|-
| 5-7
| 3
| unused (0)
|}

Note: the Sprite X, Y and magnification are in the same order as the ASIC registers

3. This is a direct copy of the palette in CPC+ ASIC Ram. There are 32 colours each with 2-bytes per colour.

4. These bytes in the snapshot represent the last value written to these ASIC registers.

5. These bytes represent the inputs to the analogue channels.

6. The attributes for each DMA channel take 4 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| DMA Channel address (see note)
|-
| 2
| 1
| DMA Channel prescalar (see note)
|-
| 3
| 1
| unused (0)
|}

Note: the DMA address and prescalar are in the same order as the ASIC registers.

7 These registers are internal to the CPC+ and define the current DMA operation:

| loop address (note b)
|-
| 4
| 2
| pause count (note c)
|-
| 6
| 1
| pause prescalar count (note d)
|}

a. This value represents the number of loops remaining. 0 = none. This count is between 0..0FFF. This counter counts down.

b. This is the Amstrad memory address to loop back to. It is a pointer to the DMA instruction after the last REPEAT instruction.

c. This value represents the pause count and the count is between 0...0FFF. (TO BE CHECKED: down counter? what exactly does it represent)

d. This value represents the pause prescalar count and the count is between 0..FF. (TO BE CHECKED: down counter? what exactly does it represent)

8. This value represents the last value written to this I/O port. Winape uses 8a and not 8b. This value has bits 7,6,5 set to 1,0 and 1 respectively. 8b is in the original specification and is written by both ACE and No$CPC.

9. This value represents the lock status of RMR2. If locked, RMR2 can't be accessed otherwise it can.

10. This value represents the current unlock sequence state.

{|

|-
| 2..10

| ASIC is waiting for byte from unlock sequence. e.g. if "2", ASIC is waiting for &FF, the first byte of the unlock sequence. if "3" ASIC is waiting for &77, the second byte of the unlock sequence.
|}

== DSCA,DSCB ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

The DSCA block contains the filename of the disc image inserted into drive A. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

DSCB is similar to DSCA but stores the filename of the disc image inserted into drive B.

== TAPE ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

The TAPE block contains the filename of the tape image inserted. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

== ROMS ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

This block contains a list of filenames for each ROM (and cartridge) that is defined. The length of the block is the length for all strings.

If a ROM is not defined, a single NUL (0) byte is present, otherwise there is a null terminated 8-bit ASCII string.

First in the list is the filename (or internal name) for the cartridge (prefixed with a 'A' character), followed by lower rom and then upper roms 0-31 (WinAPE) or 0-255 (ACE).

WinAPE lists internal ROMs by their internal name (the name listed in the drop down when you configure the roms, e.g. OS464).
ACE always put the actual file name, even for internal ROMs (e.g. System/Firmware_v3.rom).

After the list of the upper ROMs, ACE also put the names of the internal Basic and AMSDOS ROMs.
Then, the presence of the "CartridgeKeepExtROM" let ACE know if the cartridge ROMs should disable installed external upper ROMs or not (depending on user preferences).

NOTE: The selected Multiface ROM is not saved in the snapshot.

== INFO ==

This chunk is written by No$CPC. It contains an 8-bit ASCII string with the version information for No$CPC.

== MEM0-8 ==

The MEM0-8 chunks contain at most 64KB of data. The data may be compressed or stored uncompressed. If the size is exactly 65536 bytes the data is uncompressed, otherwise it is compressed. Up to 512KB additional RAM can be stored in a snapshot.

The compression scheme is RLE with 0x0e5 as the control byte.

Data is encoded as:

* <byte> for a single occurrence of a byte (not 0x0e5) (e.g. 0x013)
* 0x0e5,<count>,<byte> for multiple occurances of a byte (e. 0x0e5,0x04,0x013 for 0x013 repeated 4 times)
* 0x0e5,0 for a single 0x0e5 byte (e.g. 0x0e5)

The blocks are:

* MEM0 - main 64KB ram
* MEM1 - c4,c5,c6,c7 configurations (extra 64KB ram in 128KB machines) (256KB Dk'Tronics RAM, X-MEM)
* MEM2 - cc,cd,ce,cf configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM3 - d4,d5,d6,d7 configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM4 - dc,dd,de,df configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM5 - e4,e5,e6,e7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM6 - ec,ed,ee,ef configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM7 - f4,f5,f6,f7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM8 - fc,fd,fe,ff configurations (256KB Dk'Tronics Silicon Disk, X-MEM)

=== Notes ===

1. A snapshot may contain a mix of "standard" memory data (e.g. the data follows the header and is uncompressed) and additional MEM blocks as required.

2. If the snapshot is not compressed, then up to 128KB will be stored as "standard" memory data, the additional RAM stored in MEM2-MEM8 blocks.

3. If the snapshot is compressed, then the "standard" memory data will have 0 size and there will be a MEM0 in addition to the additional memory blocks.

4. Version 3 doesn't require memory to be continuous. A Dk'tronics silicon disk on it's own can be described with this version.

5. WinAPE allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.

6. ACE can save additional memory in snapshots (up to 4MB) using the MX?? chunks.

== MX09-40 ==

This chunk is supported by ACE.

MX?? chunks allow snapshots to store up to 4160KB ram.

MX?? chunks are following MEM0-8 chunks. They are numbered from 09 to 40 (hexadecimal numbering).
Information are stored compressed like in MEM0-8 chunks.

== BRKC ==

This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.
The number of stored breakpoints in the chunk is given by the chunk size divided by 216 (the size on one breakpoint data structure).

''Example : FlagC AND (HL=DE OR HL=&5000)''

2. The map type determines the memory layout for which the breakpoint is valid.
The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).
* 1: Main RAM. If map bank is 0, then linear main RAM is considered. If map bank is 1, then main RAM from &c000-&ffff mapped as &4000-&7fff is considered. Map page is ignored (always 0).
* 2: Extension RAM. Map bank is the 16K extension bank number (0-3). Map page is the 64K extension page number (0-31).
* 3: Extension ROM. Map bank is the ROM slot id (0-255). Map page is ignored (always 0).
* 4: Firmware ROM. Map bank and page are ignored (always 0).
* 5: Cartridge ROM. Map bank is the 16K ROM bank number (0-31). Map page is ignored (always 0).
* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

== SYMB ==

This chunk is written by ACE when some symbols are declared. When loading a snapshot, the symbols found in this chunk are added to the alreading existing ones.

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 00
| 1
| Length on the symbol name (n). 0 is an invalid value.
|-
| 01
| n
| Symbol name (note 1).
|-
| n+1
| 1
| Symbol memory map type (note 2).
|-
| n+2
| 1
| Symbol memory map bank (note 2).
|-
| n+3
| 1
| Symbol memory map page (note 2).
|-
| n+4
| 2
| Reserved for future usage, always 0 for now.
|-
| n+6
| 1
| Symbol type (0: absolute, 1: relative).
|-
| n+7
| 2
| Address of the symbol (MSB first).
|-
| ...
| Same sequence repeated until the end of the chunk is reached.
|}

===Notes===

1. Symbol are (obviously) limited to 255 characters, cannot begin with a number (0-9), and only a limited set of ASCII char is allowed (a-z, A-Z, 0-9, _).
2. The map type determines the memory layout for which the symbol is valid. The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).
* 1: Main RAM. If map bank is 0, then linear main RAM is considered. If map bank is 1, then main RAM from &c000-&ffff mapped as &4000-&7fff is considered. Map page is ignored (always 0).
* 2: Extension RAM. Map bank is the 16K extension bank number (0-3). Map page is the 64K extension page number (0-31).
* 3: Extension ROM. Map bank is the ROM slot id (0-255). Map page is ignored (always 0).
* 4: Firmware ROM. Map bank and page are ignored (always 0).
* 5: Cartridge ROM. Map bank is the 16K ROM bank number (0-31). Map page is ignored (always 0).
* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

== BRKS ==

This chunk is written by WinAPE when some breakpoints are set.
ACE can import breakpoints from this chunk but won't create it (BRKC is used instead).

The chunk contains 1 or more breakpoints.

Each breakpoint has the form:
* 2 bytes: address (LSB first)
* 1 byte: location (0: base 64K RAM, 1: extended RAM)
* 2 bytes: condition (?)

== WABP ==

This chunk is written by WinAPE when some breakpoints are set.
The exact details are begin worked out.

It seems to be:

4 bytes - number of user breakpoints

Each user breakpoint:

type,
4 byte address

Then, 4 bytes - number of memory breakpoints

Each memory breakpoint:

Then, 4 bytes - number of i/o breakpoints:

Each i/o breakpoint:

2 bytes flags? (6000 read, a400 write)
2 bytes port addr mask
2 bytes port addr
4 bytes counter
4 bytes condition string length, followed by condition string (not null terminated)

== DARS ==

This chunk is written by WinAPE when some data areas are set.

The number of stored data areas in the chunk is given by the chunk size divided by 10 (the size of one data area data structure).

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 00
| 4
| Address (LSB first) (note 1)
|-
| 04
| 4
| Area size (LSB first)
|-
| 08
| 1
| Data type (0=byte,1=word)
|-
| 09
| 1
| Labels (1=marked by user as having labels)
|-
|}

=== Notes ===

1. Winape's addressing scheme is 4 bytes. The upper 16-bits effectively define the internal 64KB pages it uses.

== REMU ==

This chunk is written RASM and contains information about symbols and breakpoints.
ACE will import informations from this chunk but won't write it (SYMB and BRKC are used instead).

== RM00-FF ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

The RM00-FF chunks contain at most 16KB of data representing the contents of the related external upper ROMs number. The data may be compressed or stored uncompressed. If the size is exactly 16384 bytes the data is uncompressed, otherwise it is compressed. Up to 2MB of external upper ROMs can be stored in a snapshot.

The compression scheme is identical to the one from MEM0-7 chunks.

== LOWR ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal firmware ROM contents.

== BASR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal Basic ROM contents.

== DOSR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal AMSDOS ROM contents.

== CART ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It stores the contents of the inserted cartridge ROM. Extended cartridges are also supported.

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 00
| 1
| Type of compression (0: uncompressed, &5E: RLE compressed)
|-
| 01
| 4
| Physical size of the cartridge in bytes, must be 16, 32, 64, 128, 256 or 512KB (MSB first)
|-
| 05
| 2
| Number of cartridges, 1: for normal cartridges, extended cartridges otherwise (MSB first)
|-
| 07
| 2
| Flags, bit 0 set if the external upper ROMs must be disabled, other bits set to 0 (MSB first)
|-
| 09
| x
| Cartridge data contents (either compressed or not depending on type of compression)
|-
|}

== PLUG ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

This chunk stores the names of the plugins which should be enabled for the snapshot.

All names are stored one after the other, in the form of binary strings (first byte containing the plugin name length followed by the the actual string).
The names stored are the actual names of the plugins libraries (e.g. "multiface2.acepansion").

= Mass-storage =
Emulator support for mass-storage expansions is as follows:
*[[Dobbertin Harddisc]] is emulated by MAME
*[[UIDE Universal IDE adapter cards for Z-80 computers|uIDE]] is emulated by Arnold
*[[Symbiface II]] IDE/PATA interface or compatible ([[X-Mass]], [https://github.com/salafek/cyboard-for-cpc Cyboard]) is emulated by ACE, Caprice Forever, MAME, WinAPE, WinCPC, Arnold, Virtual CPC
*[[Albireo]] is emulated by ACE, Caprice Forever
*[[M4 Board]] is emulated by CPCemu
*[[Vortex Winchester Drive]], [[ULIfAC|USIfAC / ULIfAC]] and [[Symbiface 3|Symbiface3 / RSF3]] are not supported by emulators

= CPC cartridge slot =
Emulator support for a CPC cartridge slot is as follows:
*[[Dandanator]] brings a non-standard physical cartridge port and a very exotic non-standard memory mapper that spies on Z80 instructions (sacrificing compatibility without any justification). It is emulated by ACE, Retro Virtual Machine, CPCEC, ZEsarUX, DSP
*[[Plus2CPC]] brings a standard physical Plus cartridge port to the CPC. It is not supported by emulators
*[[Play2CPC]] is an evolution of the [[Plus2CPC]], adding RMR2 Plus mapping, R/W cartridge support, CRTC cursor raster interrupt and a 3-channel soundchip conforming to the [[PlayCity]] base spec. Play2CPC is emulated by ACE
*[[M4 Board]] simulates a standard Plus cartridge port on the CPC and handles standard CPR files. M4 Board is emulated by CPCemu

= Audio devices =
Emulator support is as follows:
*[[Amstrad SSA-1 Speech Synthesizer|SSA-1 speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME
*[[Dk'tronics Speech Synthesizer|Dk'Tronics speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME

*[[PlayCity]] is fully emulated by ACE, MAME, Arnold, SugarBox. The audio part of [[PlayCity]] is emulated by Caprice Forever, JavaCPC, CPCEC
*[[Play2CPC]] implements the PlayCity base spec (aka Arcade Sound System). It has one additional soundchip instead of two and no CTC chip. It is emulated by ACE
*[[Willy|Willy OPL3]] is emulated by ACE
*[[Willy|Willy MIDI]] is emulated only by ACE for Haiku
*[[Music Machine]], [https://github.com/lambdamikel/Speak-SID Speak&SID], [https://github.com/lambdamikel/LambdaSpeak3 LambdaSpeak], [https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/amsdap-amstrad-msx-adapter-connecting-any-msx-io-hardware-to-the-cpc/ Amsdap (SE-One, Moonsound, etc...)] are not supported by emulators

= Rewind feature =
ACE-DL has a rewind feature, but it is not as good as it could be: [https://youtu.be/wIKGvpnJLUo Demonstration of rewind in ACE-DL]

At the moment, only the RetroArch CPC emulator has a proper rewind feature: [https://youtu.be/YwilYlSe5LQ Demonstration of rewind in RetroArch]. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

A very simple approach would be to make a SNA for each frame and limit the RAM snapshot to 128KB, which is ok for 99% of CPC software. For a 10-seconds long rewind functionality, only 64MB RAM is needed (128KB * 50 frames * 10 seconds).

A more efficient approach is to store only the values that are changed in RAM between two frames, so that RAM can be restored when rewinding. This allows for long-rewinds, even of a CPC equipped with a 4MB RAM expansion. Proof of it is the GBA emulator [https://youtu.be/Sfc_1NKbiKg SkyEmu demonstrating super long rewind] while needing very few RAM.

For debugging, going back to the previous instruction is easily implemented. The emulator has to store the time when the previous instruction was executed so that he can go back to that instruction. In the same way, emulators can provide access to the previous HBL, IRQ, VBL, etc.

= Emulator Detection =

If you want to promote usage of real CPC computers, you can detect CPC emulators by:
*Checking if the memory is initialized with zeroes, as real machines have random memory values at boot
*Focusing on the minute details in Z80, CRTC and PPI chips. They are most often wrong in emulators
*Examining the FDC chip. It is only replicated more or less superficially in all emulators because the internals of the chip are still unknown

Combining these methods will definitely get you a 100% success rate in detecting emulators, even the toughest ones.

There is also this initiative for emulators who willingly want to be detected: [[Emulator_IDs|Emulator IDs]]

= Mass-storage =
Emulator support for mass-storage expansions is as follows:
*[[Dobbertin Harddisc]] is emulated by MAME
*[[UIDE Universal IDE adapter cards for Z-80 computers|uIDE]] is emulated by Arnold
*[[Symbiface II]] IDE/PATA interface or compatible ([[X-Mass]], [https://github.com/salafek/cyboard-for-cpc Cyboard]) is emulated by ACE, Caprice Forever, MAME, WinAPE, WinCPC, Arnold, Virtual CPC
*[[Albireo]] is emulated by ACE, Caprice Forever
*[[M4 Board]] is emulated by CPCemu
*[[Vortex Winchester Drive]], [[ULIfAC|USIfAC / ULIfAC]] and [[Symbiface 3|Symbiface3 / RSF3]] are not supported by emulators

= CPC cartridge slot =
Emulator support for a CPC cartridge slot is as follows:
*[[Dandanator]] brings a non-standard physical cartridge port and a very exotic non-standard memory mapper that spies on Z80 instructions (sacrificing compatibility without any justification). It is emulated by ACE, Retro Virtual Machine, CPCEC, ZEsarUX, DSP
*[[Plus2CPC]] brings a standard physical Plus cartridge port to the CPC. It is not supported by emulators
*[[Play2CPC]] is an evolution of the [[Plus2CPC]], adding RMR2 Plus mapping, R/W cartridge support, CRTC cursor raster interrupt and a 3-channel soundchip conforming to the [[PlayCity]] base spec. Play2CPC is emulated by ACE
*[[M4 Board]] simulates a standard Plus cartridge port on the CPC and handles standard CPR files. M4 Board is emulated by CPCemu

= Audio devices =
Emulator support is as follows:
*[[Amstrad SSA-1 Speech Synthesizer|SSA-1 speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME
*[[Dk'tronics Speech Synthesizer|Dk'Tronics speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME

*[[PlayCity]] is fully emulated by ACE, MAME, Arnold, SugarBox. The audio part of [[PlayCity]] is emulated by Caprice Forever, JavaCPC, CPCEC
*[[Play2CPC]] implements the PlayCity base spec (aka Arcade Sound System). It has one additional soundchip instead of two and no CTC chip. It is emulated by ACE
*[[Willy|Willy OPL3]] is emulated by ACE
*[[Willy|Willy MIDI]] is emulated only by ACE for Haiku
*[[Music Machine]], [https://github.com/lambdamikel/Speak-SID Speak&SID], [https://github.com/lambdamikel/LambdaSpeak3 LambdaSpeak], [https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/amsdap-amstrad-msx-adapter-connecting-any-msx-io-hardware-to-the-cpc/ Amsdap (SE-One, Moonsound, etc...)] are not supported by emulators

= Rewind feature =
ACE-DL has a rewind feature, but it is not as good as it could be: [https://youtu.be/wIKGvpnJLUo Demonstration of rewind in ACE-DL]

At the moment, only the RetroArch CPC emulator has a proper rewind feature: [https://youtu.be/YwilYlSe5LQ Demonstration of rewind in RetroArch]. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

A very simple approach would be to make a SNA for each frame and limit the RAM snapshot to 128KB, which is ok for 99% of CPC software. For a 10-seconds long rewind functionality, only 64MB RAM is needed (128KB * 50 frames * 10 seconds).

A more efficient approach is to store only the values that are changed in RAM between two frames, so that RAM can be restored when rewinding. This allows for long-rewinds, even of a CPC equipped with a 4MB RAM expansion. Proof of it is the GBA emulator [https://youtu.be/Sfc_1NKbiKg SkyEmu demonstrating super long rewind] while needing very few RAM.

For debugging, going back to the previous instruction is easily implemented. The emulator has to store the time when the previous instruction was executed so that he can go back to that instruction. In the same way, emulators can provide access to the previous HBL, IRQ, VBL, etc.

= Emulator Detection =

If you want to promote usage of real CPC computers, you can detect CPC emulators by:
*Checking if the memory is initialized with zeroes, as real machines have random memory values at boot
*Focusing on the minute details in Z80, CRTC and PPI chips. They are most often wrong in emulators
*Examining the FDC chip. It is only replicated more or less superficially in all emulators because the internals of the chip are still unknown

Combining these methods will definitely get you a 100% success rate in detecting emulators, even the toughest ones.

= Mass-storage =
Emulator support for mass-storage expansions is as follows:
*[[Dobbertin Harddisc]] is emulated by MAME
*[[UIDE Universal IDE adapter cards for Z-80 computers|uIDE]] is emulated by Arnold
*[[Symbiface II]] IDE/PATA interface or compatible ([[X-Mass]], [https://github.com/salafek/cyboard-for-cpc Cyboard]) is emulated by ACE, Caprice Forever, MAME, WinAPE, WinCPC, Arnold, Virtual CPC
*[[Albireo]] is emulated by ACE, Caprice Forever
*[[M4 Board]] is emulated by CPCemu
*[[Vortex Winchester Drive]], [[ULIfAC|USIfAC / ULIfAC]] and [[Symbiface 3|Symbiface3 / RSF3]] are not supported by emulators

= CPC cartridge slot =
Emulator support for a CPC cartridge slot is as follows:
*[[Dandanator]] brings a non-standard physical cartridge port and a very exotic non-standard memory mapper that spies on Z80 instructions (sacrificing compatibility without any justification). It is emulated by ACE, Retro Virtual Machine, CPCEC, ZEsarUX, DSP
*[[Plus2CPC]] brings a standard physical Plus cartridge port to the CPC. It is not supported by emulators
*[[Play2CPC]] is an evolution of the [[Plus2CPC]], adding RMR2 Plus mapping, R/W cartridge support, CRTC cursor raster interrupt and a 3-channel soundchip conforming to the [[PlayCity]] base spec. Play2CPC is emulated by ACE
*[[M4 Board]] simulates a standard Plus cartridge port on the CPC and handles standard CPR files. M4 Board is emulated by CPCemu

= Audio devices =
Emulator support is as follows:
*[[Amstrad SSA-1 Speech Synthesizer|SSA-1 speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME
*[[Dk'tronics Speech Synthesizer|Dk'Tronics speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME

*[[PlayCity]] is fully emulated by ACE, MAME, Arnold, SugarBox. The audio part of [[PlayCity]] is emulated by Caprice Forever, JavaCPC, CPCEC
*[[Play2CPC]] implements the PlayCity base spec (aka Arcade Sound System). It has one additional soundchip instead of two and no CTC chip. It is emulated by ACE
*[[Willy|Willy OPL3]] is emulated by ACE
*[[Willy|Willy MIDI]] is emulated only by ACE for Haiku
*[[Music Machine]], [https://github.com/lambdamikel/Speak-SID Speak&SID], [https://github.com/lambdamikel/LambdaSpeak3 LambdaSpeak], [https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/amsdap-amstrad-msx-adapter-connecting-any-msx-io-hardware-to-the-cpc/ Amsdap (SE-One, Moonsound, etc...)] are not supported by emulators

= Rewind feature =
ACE-DL has a rewind feature, but it is not as good as it could be: [https://youtu.be/wIKGvpnJLUo Demonstration of rewind in ACE-DL]

At the moment, only the RetroArch CPC emulator has a proper rewind feature: [https://youtu.be/YwilYlSe5LQ Demonstration of rewind in RetroArch]. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

A very simple approach would be to make a SNA for each frame and limit the RAM snapshot to 128KB, which is ok for 99% of CPC software. For a 10-seconds long rewind functionality, only 64MB RAM is needed (128KB * 50 frames * 10 seconds).

A more efficient approach is to store only the values that are changed in RAM between two frames, so that RAM can be restored when rewinding. This allows for long-rewinds, even of a CPC equipped with a 4MB RAM expansion. Proof of it is the GBA emulator [https://youtu.be/Sfc_1NKbiKg SkyEmu demonstrating super long rewind] while needing very few RAM.

For debugging, going back to the previous instruction is easily implemented. The emulator has to store the time when the previous instruction was executed so that he can go back to that instruction. In the same way, emulators can provide access to the previous HBL, IRQ, VBL, etc.

= Emulator Detection =

If you want to promote usage of real CPC computers, you can detect CPC emulators by:
*Checking if the memory is initialized with zeroes, as real machines have random memory values at boot
*Focusing on the minute details in Z80, CRTC and PPI chips. They are most often wrong in emulators
*Examining the FDC chip. It is only replicated more or less superficially in all emulators because the internals of the chip are still unknown

Combining these methods will definitely get you a 100% success rate in detecting emulators, even the toughest ones.

= Mass-storage =
Emulator support for mass-storage expansions is as follows:
*[[Dobbertin Harddisc]] is emulated by MAME
*[[UIDE Universal IDE adapter cards for Z-80 computers|uIDE]] is emulated by Arnold
*[[Symbiface II]] IDE/PATA interface or compatible ([[X-Mass]], [https://github.com/salafek/cyboard-for-cpc Cyboard]) is emulated by ACE, Caprice Forever, MAME, WinAPE, WinCPC, Arnold, Virtual CPC
*[[Albireo]] is emulated by ACE, Caprice Forever
*[[M4 Board]] is emulated by CPCemu
*[[Vortex Winchester Drive]], [[ULIfAC|USIfAC / ULIfAC]] and [[Symbiface 3|Symbiface3 / RSF3]] are not supported by emulators

= CPC cartridge slot =
Emulator support for a CPC cartridge slot is as follows:
*[[Dandanator]] brings a non-standard physical cartridge port and a very exotic non-standard memory mapper that spies on Z80 instructions (sacrificing compatibility without any justification). It is emulated by ACE, Retro Virtual Machine, CPCEC, ZEsarUX, DSP
*[[Plus2CPC]] brings a standard physical Plus cartridge port to the CPC. It is not supported by emulators
*[[Play2CPC]] is an evolution of the [[Plus2CPC]], adding RMR2 Plus mapping, R/W cartridge support, CRTC cursor raster interrupt and a 3-channel soundchip conforming to the [[PlayCity]] base spec. Play2CPC is emulated by ACE
*[[M4 Board]] simulates a standard Plus cartridge port on the CPC and handles standard CPR files. M4 Board is emulated by CPCemu

= Audio devices =
Emulator support is as follows:
*[[Amstrad SSA-1 Speech Synthesizer|SSA-1 speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME
*[[Dk'tronics Speech Synthesizer|Dk'Tronics speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME

*[[PlayCity]] is fully emulated by ACE, MAME, Arnold, SugarBox. The audio part of [[PlayCity]] is emulated by Caprice Forever, JavaCPC, CPCEC
*[[Play2CPC]] implements the PlayCity base spec (aka Arcade Sound System). It has one additional soundchip instead of two and no CTC chip. It is emulated by ACE
*[[Willy|Willy OPL3]] is emulated by ACE
*[[Willy|Willy MIDI]] is emulated only by ACE for Haiku
*[[Music Machine]], [https://github.com/lambdamikel/Speak-SID Speak&SID], [https://github.com/lambdamikel/LambdaSpeak3 LambdaSpeak], [https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/amsdap-amstrad-msx-adapter-connecting-any-msx-io-hardware-to-the-cpc/ Amsdap (SE-One, Moonsound, etc...)] are not supported by emulators

= Rewind feature =
ACE-DL has a rewind feature, but it is not as good as it could be: [https://youtu.be/wIKGvpnJLUo Demonstration of rewind in ACE-DL]

At the moment, only the RetroArch CPC emulator has a proper rewind feature: [https://youtu.be/YwilYlSe5LQ Demonstration of rewind in RetroArch]. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

A very simple approach would be to make a SNA for each frame and limit the RAM snapshot to 128KB, which is ok for 99% of CPC software. For a 10-seconds long rewind functionality, only 64MB RAM is needed (128KB * 50 frames * 10 seconds).

A more efficient approach is to store only the values that are changed in RAM between two frames, so that RAM can be restored when rewinding. This allows for long-rewinds, even of a CPC equipped with a 4MB RAM expansion. Proof of it is the GBA emulator [https://youtu.be/Sfc_1NKbiKg SkyEmu demonstrating super long rewind] while needing very few RAM.

For debugging, going back to the previous instruction is easily implemented. The emulator has to store the time when the previous instruction was executed so that he can go back to that instruction. In the same way, emulators can provide access to the previous HBL, IRQ, VBL, etc.

= Emulator Detection =

If you want to promote usage of real CPC computers, you can detect CPC emulators by:
*Checking if the memory is initialized with zeroes, as real machines have random memory values at boot
*Focusing on the minute details in Z80, CRTC and PPI chips. They are most often wrong in emulators
*Examining the FDC chip. It is only replicated more or less superficially in all emulators because the internals of the chip are still unknown

Combining these methods will definitely get you a 100% success rate in detecting emulators, even the toughest ones.

*[[Vortex Winchester Drive]], [[ULIfAC|USIfAC / ULIfAC]] and [[Symbiface 3|Symbiface3 / RSF3]] are not supported by emulators

= CPC cartridge slot =
Emulator support for a CPC cartridge slot is as follows:
*[[Dandanator]] brings a non-standard physical cartridge port and a very exotic non-standard memory mapper that spies on Z80 instructions (sacrificing compatibility without any justification). It is emulated by ACE, Retro Virtual Machine, CPCEC, ZEsarUX, DSP
*[[Plus2CPC]] brings a standard physical Plus cartridge port to the CPC. It is not supported by emulators
*[[Play2CPC]] is an evolution of the [[Plus2CPC]], adding RMR2 Plus mapping, R/W cartridge support, CRTC cursor raster interrupt and a 3-channel soundchip conforming to the [[PlayCity]] base spec. Play2CPC is emulated by ACE
*[[M4 Board]] simulates a standard Plus cartridge port on the CPC and handles standard CPR files. M4 Board is emulated by CPCemu

= Audio devices =
Emulator support is as follows:
*[[Amstrad SSA-1 Speech Synthesizer|SSA-1 speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME
*[[Dk'tronics Speech Synthesizer|Dk'Tronics speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME

*[[Play2CPC]] implements the PlayCity base spec (aka Arcade Sound System). It has one additional soundchip instead of two and no CTC chip. It is emulated by ACE
*[[Willy|Willy OPL3]] is emulated by ACE
*[[Willy|Willy MIDI]] is emulated only by ACE for Haiku
*[[Music Machine]], [https://github.com/lambdamikel/Speak-SID Speak&SID], [https://github.com/lambdamikel/LambdaSpeak3 LambdaSpeak], [https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/amsdap-amstrad-msx-adapter-connecting-any-msx-io-hardware-to-the-cpc/ Amsdap (SE-One, Moonsound, etc...)] are not supported by emulators

= Rewind feature =
ACE-DL has a rewind feature, but it is not as good as it could be: [https://youtu.be/wIKGvpnJLUo Demonstration of rewind in ACE-DL]

At the moment, only the RetroArch CPC emulator has a proper rewind feature: [https://youtu.be/YwilYlSe5LQ Demonstration of rewind in RetroArch]. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

A very simple approach would be to make a SNA for each frame and limit the RAM snapshot to 128KB, which is ok for 99% of CPC software. For a 10-seconds long rewind functionality, only 64MB RAM is needed (128KB * 50 frames * 10 seconds).

A more efficient approach is to store only the values that are changed in RAM between two frames, so that RAM can be restored when rewinding. This allows for long-rewinds, even of a CPC equipped with a 4MB RAM expansion. Proof of it is the GBA emulator [https://youtu.be/Sfc_1NKbiKg SkyEmu demonstrating super long rewind] while needing very few RAM.

For debugging, going back to the previous instruction is easily implemented. The emulator has to store the time when the previous instruction was executed so that he can go back to that instruction. In the same way, emulators can provide access to the previous HBL, IRQ, VBL, etc.

= Emulator Detection =

If you want to promote usage of real CPC computers, you can detect CPC emulators by:
*Checking if the memory is initialized with zeroes, as real machines have random memory values at boot
*Focusing on the minute details in Z80, CRTC and PPI chips. They are most often wrong in emulators
*Examining the FDC chip. It is only replicated more or less superficially in all emulators because the internals of the chip are still unknown

Combining these methods will definitely get you a 100% success rate in detecting emulators, even the toughest ones.

= CPC cartridge slot =
Emulator support for a CPC cartridge slot is as follows:
*[[Dandanator]] brings a non-standard physical cartridge port and a very exotic non-standard memory mapper that spies on Z80 instructions (sacrificing compatibility without any justification). It is emulated by ACE, Retro Virtual Machine, CPCEC, ZEsarUX, DSP
*[[Plus2CPC]] brings a standard physical Plus cartridge port to the CPC. It is not supported by emulators
*[[Play2CPC]] is an evolution of the [[Plus2CPC]], adding RMR2 Plus mapping, R/W cartridge support, CRTC cursor raster interrupt and a 3-channel soundchip conforming to the [[PlayCity]] base spec. Play2CPC is emulated by ACE
*[[M4 Board]] simulates a standard Plus cartridge port on the CPC and handles standard CPR files. M4 Board is emulated by CPCemu

= Audio devices =
Emulator support is as follows:
*[[Amstrad SSA-1 Speech Synthesizer|SSA-1 speech synthesizer]] is emulated by ACE, Caprice Forever, JavaCPC, MAME

*[[Willy|Willy OPL3]] is emulated by ACE
*[[Willy|Willy MIDI]] is emulated only by ACE for Haiku
*[[Music Machine]], [https://github.com/lambdamikel/Speak-SID Speak&SID], [https://github.com/lambdamikel/LambdaSpeak3 LambdaSpeak], [https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/amsdap-amstrad-msx-adapter-connecting-any-msx-io-hardware-to-the-cpc/ Amsdap (SE-One, Moonsound, etc...)] are not supported by emulators

= Rewind feature =
ACE-DL has a rewind feature, but it is not as good as it could be: [https://youtu.be/wIKGvpnJLUo Demonstration of rewind in ACE-DL]

At the moment, only the RetroArch CPC emulator has a proper rewind feature: [https://youtu.be/YwilYlSe5LQ Demonstration of rewind in RetroArch]. To reverse the game, the user press and hold the rewind button. And at any point, releasing the button makes time goes forward again.

A very simple approach would be to make a SNA for each frame and limit the RAM snapshot to 128KB, which is ok for 99% of CPC software. For a 10-seconds long rewind functionality, only 64MB RAM is needed (128KB * 50 frames * 10 seconds).

A more efficient approach is to store only the values that are changed in RAM between two frames, so that RAM can be restored when rewinding. This allows for long-rewinds, even of a CPC equipped with a 4MB RAM expansion. Proof of it is the GBA emulator [https://youtu.be/Sfc_1NKbiKg SkyEmu demonstrating super long rewind] while needing very few RAM.

For debugging, going back to the previous instruction is easily implemented. The emulator has to store the time when the previous instruction was executed so that he can go back to that instruction. In the same way, emulators can provide access to the previous HBL, IRQ, VBL, etc.

= Emulator Detection =

If you want to promote usage of real CPC computers, you can detect CPC emulators by:
*Checking if the memory is initialized with zeroes, as real machines have random memory values at boot
*Focusing on the minute details in Z80, CRTC and PPI chips. They are most often wrong in emulators
*Examining the FDC chip. It is only replicated more or less superficially in all emulators because the internals of the chip are still unknown

Combining these methods will definitely get you a 100% success rate in detecting emulators, even the toughest ones.

OffseT:

= Snapshot (.SNA) file format =

The format was first defined for the [[CPCEMU|CPCEMU]] emulator but is now widely supported. The format was originally defined by [[Marco Vieth|Marco Vieth]]. Version 3 was defined by [[Ulrich Doewich|Ulrich Doewich]], [[Martin Korth|Martin Korth]], [[Richard Wilson|Richard Wilson]] and [[Kevin Thacker|Kevin Thacker]].

There are 3 versions defined in this document. Version 3 is the most recent and is currently supported by a few of the most recent emulators.

Snapshots produced with [[CPCE|CPCE]] appears to be the most compatible and will run correctly using any emulator.

== Notes ==

1. All multi-byte values are stored in little-endian format (low byte followed by higher bytes).

2. "IFF0" reflects the state of the maskable interrupt (INT). "IFF1" is used to store the state of IFF0 when a non-maskable interrupt (NMI) is executed. Bit 0 of these bytes is significant. For CPCEMU compatibility, these bytes should be set to "1" when the IFF flip-flop is "1" and "0" when the flip-flop is "0". For compatibility with other emulators, bits 7-1 should be set to "0". When bit 0 of "IFF0" is "0" maskable interrupts will be ignored. When bit 0 of "IFF1" is "1" maskable interrupts will be acknowledged and executed. See the document about the Z80 for more information.

3. This byte will be 0, 1 or 2 for the interrupt modes 0, 1 or 2. The interrupt mode is set using the "IM x" instructions. See the document about the Z80 for more information.

4. These registers are from the alternate register set of the Z80.

5. These registers are 16-bit. "low" indicates bits 7..0, "high"indicates bits 15..8.

6. This byte represents the inputs to PPI port A regardless of the input/output setting of this port.

7. This byte represents the inputs to PPI port B regardless of the input/output setting of this port.

8. This byte represents the outputs from port C regardless of the input/output setting of this port.

9. This byte represents the PPI control byte which defines the input/output and mode of each port and not the last value written to this port. For CPCEMU compatibility bit 7 of this byte must be set to "1".

10. This byte in the snapshot represents the selected pen register of the Gate-Array. This byte is the last value written to this port. Bit 7,6,5 should be set to "0".

11. This byte in the snapshot represents the multi-configuration register of the Gate-Array. This byte is the last byte written to this register. For CPCEMU compatibility, bit 7 should be set to "1" and bit 6 and bit 5 set to "0".

12. These bytes are the current palette. For CPCEMU compatibility, these bytes should have bit 7=bit 6=bit 5="0". Bits 4..0 define the colour using the hardware colour code. The colours are stored in the order pen 0, pen1, pen 2,...,pen 15 followed by border colour.

13. This byte represents a ram configuration for a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion, or the built in RAM expansion of the CPC6128 and CPC6128+. Bits 5..0 define the ram expansion code. For CPCEMU compatibility, bit 7 and bit 6 of this byte should be set to "0".

14. This byte in the snapshot represents the index of the currently selected CRTC register. For compatibility with CPCEMU this value should be in the range 0-31.

15. These bytes represent the data of the CRTC's registers.

16. This byte in the snapshot represents the last byte written to the "ROM select" I/O port.

17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.

18. the memory dump can have size 0 in version 3 and in this case all RAM is described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the main 64KB ram immediately followed by the second 64KB ram (if present) (this ram is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion. Note that CPCEMU can only write a 64K or 128K snapshot.

19. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. If standard CPC raster interrupts are used, interrupts are acknowledged and "executed" at the time they are requested, then there will be 6 interrupts executed per screen update cycle.

*CPCEMU uses a simple system to emulate the interrupts. It is assumed there are exactly 6 interrupts per screen update cycle (the interrupts are assumed to occur at a frequency of 300Hz). This byte records the interrupt number in the current screen update cycle. More accurate emulators use the correct interrupt generation method and may ignore this byte. For CPCEMU compatibility, these emulators should set this byte to "0".

*CPCEMU uses a simple system to emulate the screen display. It allows the mode to be changed in each of the 6 interrupts that occur during a single 50Hz/60Hz period. These bytes represent the mode in each of these sections, i.e. the screen modes (0,1 or 2) for the interrupts 0..5. More accurate emulators support changing of the screen mode at any point supported by the Amstrad hardware, these emulators should write "0" for all these bytes.

2. A version 2 snapshot describes Dk'Tronics/Dobbertin compatible RAM in addition to the 64KB base ram. This is a type of RAM expansion which uses the same port and paging mechanism as the extra 64KB inside the 6128. However, the RAM *MUST* be continuous, therefore it's limited to 64KB, 256KB or 512KB additional RAM. The Dk'Tronics silicon disk can't be described on it's own because it's RAM configurations do not start at C4.

The following configurations can be described:
* 64KB base + 64KB extra RAM (e.g. Dk'Tronics 64KB RAM Expansion)
* 64KB base + 256KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion)
* 64KB base + 512KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion & Dk'Tronics 256KB Silicon Disk OR X-MEM OR Symbiface 2 OR other device which provides 512KB)

JavaCPC uses this value to store up to 4MB of RAM. (e.g. [[CPC4MB]]). This type of ram is Dk'Tronics compatible and has multiple banks of 512KB. This value could be used to describe a 1MB or 2MB expansion as long as it is fully Dk'tronics compatible (e.g. rpalmer's 2MB).

== Notes ==

1. This byte in the snapshot represents the last byte written to the printer I/O port (this byte does not include the automatic inversion of the strobe caused by the Amstrad hardware).

2. This register is internal to the CRTC and counts the number of character-lines. The counter counts up. This value is in the range 0-127. (This counter is compared against CRTC register 4).

3. This register is internal to the CRTC and counts the number of raster-lines. The counter counts up. This value is in the range 0-31. (This counter is compared against CRTC register 9).

4. This register is internal to the CRTC and counts the number of raster-lines during vertical adjust. The counter counts up. This value is in the range 0-31. This should be ignored if the CRTC is not "executing" vertical. adjust.(This counter is compared against CRTC register 5).

5. This register is internal to the CRTC and counts the number of characters during horizontal sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" horizontal sync. (This counter is compared against CRTC register 3).

6. This register is internal to the CRTC and counts the number of scan-lines during vertical sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" vertical sync. (This counter is compared against CRTC register 3).

7. These bytes define the internal state of the CRTC. Each bit in these bytes represents a state.

8. When VSYNC is active, the CRTC is "executing" vertical sync, and the vertical sync width counter in the snapshot is used.

9. When HSYNC is active, the CRTC is "executing" horizontal sync width counter in the snapshot is used.

10. When Vertical total adjust is active, the CRTC is "executing" vertical total adjust and the vertical total adjust counter in the snapshot is used.

11. This register is internal to the CRTC and counts the number of characters. This counter counts up. This value is in the range 0-255. (This counter is compared against CRTC register 0).

12. This counter is internal to the GA and counts the number of HSYNCs. This counter is used to generate CPC raster interrupts. This counter counts up. This value is in the range 0-51.

13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).

14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active.

15. This is the current cylinder for each of 4 drives.

16. In WinAPE this counter is reset if a VSYNC occurs which causes the monitor to retrace vertically. This occurs if the VSYNC signal is active and this counter is greater than a threshold set by the V-Hold (normally 295 when V-Hold is 0), or if the counter reaches the maximum value (normally 351 when V-Hold is 0).

17. Since Plus emulation requires more information than simply whether an interrupt is active, this value (as used internally by WinAPE) contains:
* Bit 7 - Gate Array (or PRI) interrupt.
* Bit 6 - DMA Channel 0 interrupt.
* Bit 5 - DMA Channel 1 interrupt.
* Bit 4 - DMA Channel 2 interrupt.

It can be a combination of all or any interrupt sources. Interrupts are executed in the order raster, DMA 2, DMA 1, DMA 0.

Immediately following the memory dump there is optional data which is separated into chunks.

Each chunk of data has a header and this is followed by the data in the chunk. The header has the following format:

{|
|-
| ''Offset (Hex)''
| ''Count''
| ''Description''
|-
| 0
| 4
| Chunk name (note 1)
|-
| 4
| 4
| Chunk data length (note 2)
|}

Notes:

1. The chunks are defined with 4-byte character codes. (e.g. "CPC+"). In this example, the 4-byte character code would be stored in the file as 'C' then 'P' then 'C' then '+'.

2. The "Chunk data length" defines the length of data following the header and does not include the size of the header. This number is stored in little endian format.

3. If a emulator finds a chunk which it does not support then it should skip the chunk and continue with the next chunk in the file. Therefore an emulator author may add emulator specific chunks to the file and it will not prevent the snapshot from being used with other emulators that do not recognise the added chunks.

4. There is not a terminator chunk. The snapshot reader should determine if there are more chunks based on the size of data remaining to be read from the file.

=Version 3 Chunks=

The following chunks are currently defined:

== DSCA,DSCB ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

The DSCA block contains the filename of the disc image inserted into drive A. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

DSCB is similar to DSCA but stores the filename of the disc image inserted into drive B.

== TAPE ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

The TAPE block contains the filename of the tape image inserted. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

== ROMS ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

This block contains a list of filenames for each ROM (and cartridge) that is defined. The length of the block is the length for all strings.

If a ROM is not defined, a single NUL (0) byte is present, otherwise there is a null terminated 8-bit ASCII string.

First in the list is the filename (or internal name) for the cartridge (prefixed with a 'A' character), followed by lower rom and then upper roms 0-31 (WinAPE) or 0-255 (ACE).

WinAPE lists internal ROMs by their internal name (the name listed in the drop down when you configure the roms, e.g. OS464).
ACE always put the actual file name, even for internal ROMs (e.g. System/Firmware_v3.rom).

After the list of the upper ROMs, ACE also put the names of the internal Basic and AMSDOS ROMs.
Then, the presence of the "CartridgeKeepExtROM" let ACE know if the cartridge ROMs should disable installed external upper ROMs or not (depending on user preferences).

NOTE: The selected Multiface ROM is not saved in the snapshot.

== INFO ==

This chunk is written by No$CPC. It contains an 8-bit ASCII string with the version information for No$CPC.

== MEM0-8 ==

The MEM0-8 chunks contain at most 64KB of data. The data may be compressed or stored uncompressed. If the size is exactly 65536 bytes the data is uncompressed, otherwise it is compressed. Up to 512KB additional RAM can be stored in a snapshot.

The compression scheme is RLE with 0x0e5 as the control byte.

Data is encoded as:

* <byte> for a single occurrence of a byte (not 0x0e5) (e.g. 0x013)
* 0x0e5,<count>,<byte> for multiple occurances of a byte (e. 0x0e5,0x04,0x013 for 0x013 repeated 4 times)
* 0x0e5,0 for a single 0x0e5 byte (e.g. 0x0e5)

The blocks are:

* MEM0 - main 64KB ram
* MEM1 - c4,c5,c6,c7 configurations (extra 64KB ram in 128KB machines) (256KB Dk'Tronics RAM, X-MEM)
* MEM2 - cc,cd,ce,cf configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM3 - d4,d5,d6,d7 configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM4 - dc,dd,de,df configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM5 - e4,e5,e6,e7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM6 - ec,ed,ee,ef configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM7 - f4,f5,f6,f7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM8 - fc,fd,fe,ff configurations (256KB Dk'Tronics Silicon Disk, X-MEM)

=== Notes ===

1. A snapshot may contain a mix of "standard" memory data (e.g. the data follows the header and is uncompressed) and additional MEM blocks as required.

2. If the snapshot is not compressed, then up to 128KB will be stored as "standard" memory data, the additional RAM stored in MEM2-MEM8 blocks.

3. If the snapshot is compressed, then the "standard" memory data will have 0 size and there will be a MEM0 in addition to the additional memory blocks.

4. Version 3 doesn't require memory to be continuous. A Dk'tronics silicon disk on it's own can be described with this version.

5. WinAPE allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.

6. ACE can save additional memory in snapshots (up to 4MB) using the MX?? chunks.

== MX09-40 ==

This chunk is supported by ACE.

MX?? chunks allow snapshots to store up to 4160KB ram.

MX?? chunks are following MEM0-8 chunks. They are numbered from 09 to 40 (hexadecimal numbering).
Information are stored compressed like in MEM0-8 chunks.

== CPC+ ==

This chunk is supported by Arnold, Winape, No$CPC and ACE. Arnold, Winape and ACE will save the block when Plus configuration enabled. No$CPC will save the block if the Plus features have been unlocked.

=== Notes ===

1. The sprite data is packed, with two sprite pixels per byte. Bits 7..4 define the first pixel and bits 3..0 define the second pixel.

2. The attributes for each sprite take 8 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| Sprite X (see note)
|-
| 2
| 2
| Sprite Y (see note)
|-
| 4
| 1
| Sprite Magnification (see note)
|-
| 5-7
| 3
| unused (0)
|}

Note: the Sprite X, Y and magnification are in the same order as the ASIC registers

3. This is a direct copy of the palette in CPC+ ASIC Ram. There are 32 colours each with 2-bytes per colour.

4. These bytes in the snapshot represent the last value written to these ASIC registers.

5. These bytes represent the inputs to the analogue channels.

6. The attributes for each DMA channel take 4 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| DMA Channel address (see note)
|-
| 2
| 1
| DMA Channel prescalar (see note)
|-
| 3
| 1
| unused (0)
|}

Note: the DMA address and prescalar are in the same order as the ASIC registers.

7 These registers are internal to the CPC+ and define the current DMA operation:

| 2
| loop address (note b)
|-
| 4
| 2
| pause count (note c)
|-
| 6
| 1
| pause prescalar count (note d)
|}

a. This value represents the number of loops remaining. 0 = none. This count is between 0..0FFF. This counter counts down.

b. This is the Amstrad memory address to loop back to. It is a pointer to the DMA instruction after the last REPEAT instruction.

c. This value represents the pause count and the count is between 0...0FFF. (TO BE CHECKED: down counter? what exactly does it represent)

d. This value represents the pause prescalar count and the count is between 0..FF. (TO BE CHECKED: down counter? what exactly does it represent)

8. This value represents the last value written to this I/O port. Winape uses 8a and not 8b. This value has bits 7,6,5 set to 1,0 and 1 respectively. 8b is in the original specification and is written by both ACE and No$CPC.

9. This value represents the lock status of RMR2. If locked, RMR2 can't be accessed otherwise it can.

10. This value represents the current unlock sequence state.

{|
|-

| ASIC is waiting for zero byte to be written, this is the second synchronisation byte required
|-
| 2..10
| synchronised
| ASIC is waiting for byte from unlock sequence. e.g. if "2", ASIC is waiting for &FF, the first byte of the unlock sequence. if "3" ASIC is waiting for &77, the second byte of the unlock sequence.

== BRKC ==

This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.
The number of stored breakpoints in the chunk is given by the chunk size divided by 216 (the size on one breakpoint data structure).

===Notes===

1. The condition is expressed using ACE syntax (similar to BASIC with AND/OR/XOR/NOT/+/-/=...).
Allowed additional syntaxes are:
*&, # or 0x for a hexadecimal number.
*% or &x for a binary number.
*AF, BC, HL, IX... for a 16-bit Z80 register.
*A, B, D, IXh, IXl... for an 8-bit Z80 register.
*FlagC, FlagNC, FlagM... for a Z80 flag.
*LineCount for the line number.
*LineCycle for the µs count on the current line.
*MemPage for the 64K expansion memory page (0-63).
*MemBankMode for the 16K expansion memory bank paging mode (0-7).
*UpperROMOn for the paging state of the upper ROM.
*UpperROMNum for the selected upper ROM number.
*LowerROMOn for the paging state of the lower ROM.
*LowerROMNum for the selected lower ROM number.
*ASICPageOn for the paging state of the I/O ASIC registers page.

''Example : FlagC AND (HL=DE OR HL=&5000)''

2. The map type determines the memory layout for which the breakpoint is valid.
The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).
* 1: Main RAM. If map bank is 0, then linear main RAM is considered. If map bank is 1, then main RAM from &c000-&ffff mapped as &4000-&7fff is considered. Map page is ignored (always 0).
* 2: Extension RAM. Map bank is the 16K extension bank number (0-3). Map page is the 64K extension page number (0-31).
* 3: Extension ROM. Map bank is the ROM slot id (0-255). Map page is ignored (always 0).
* 4: Firmware ROM. Map bank and page are ignored (always 0).
* 5: Cartridge ROM. Map bank is the 16K ROM bank number (0-31). Map page is ignored (always 0).
* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

===Notes===

1. Symbol are (obviously) limited to 255 characters, cannot begin with a number (0-9), and only a limited set of ASCII char is allowed (a-z, A-Z, 0-9, _).
2. The map type determines the memory layout for which the symbol is valid. The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).

== BRKS ==

This chunk is written by WinAPE when some breakpoints are set.
ACE can import breakpoints from this chunk but won't create it (BRKC is used instead).

The chunk contains 1 or more breakpoints.

Each breakpoint has the form:
* 2 bytes: address (LSB first)
* 1 byte: location (0: base 64K RAM, 1: extended RAM)
* 2 bytes: condition (?)

== WABP ==

This chunk is written by WinAPE when some breakpoints are set.
The exact details are begin worked out.

It seems to be:

4 bytes - number of user breakpoints

Each user breakpoint:

type,
4 byte address

Then, 4 bytes - number of memory breakpoints

Each memory breakpoint:

Then, 4 bytes - number of i/o breakpoints:

Each i/o breakpoint:

2 bytes flags? (6000 read, a400 write)
2 bytes port addr mask
2 bytes port addr
4 bytes counter
4 bytes condition string length, followed by condition string (not null terminated)

== DARS ==

This chunk is written by WinAPE when some data areas are set.

The number of stored data areas in the chunk is given by the chunk size divided by 10 (the size of one data area data structure).

=== Notes ===

1. Winape's addressing scheme is 4 bytes. The upper 16-bits effectively define the internal 64KB pages it uses.

== REMU ==

This chunk is written RASM and contains information about symbols and breakpoints.
ACE will import informations from this chunk but won't write it (SYMB and BRKC are used instead).

== RM00-FF ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

The RM00-FF chunks contain at most 16KB of data representing the contents of the related external upper ROMs number. The data may be compressed or stored uncompressed. If the size is exactly 16384 bytes the data is uncompressed, otherwise it is compressed. Up to 2MB of external upper ROMs can be stored in a snapshot.

The compression scheme is identical to the one from MEM0-7 chunks.

== LOWR ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal firmware ROM contents.

== BASR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal Basic ROM contents.

== DOSR ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal AMSDOS ROM contents.

== CART ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It stores the contents of the inserted cartridge ROM. Extended cartridges are also supported.

== PLUG ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

This chunk stores the names of the plugins which should be enabled for the snapshot.

All names are stored one after the other, in the form of binary strings (first byte containing the plugin name length followed by the the actual string).
The names stored are the actual names of the plugins libraries (e.g. "multiface2.acepansion").

== Notes ==

1. All multi-byte values are stored in little-endian format (low byte followed by higher bytes).

2. "IFF0" reflects the state of the maskable interrupt (INT). "IFF1" is used to store the state of IFF0 when a non-maskable interrupt (NMI) is executed. Bit 0 of these bytes is significant. For CPCEMU compatibility, these bytes should be set to "1" when the IFF flip-flop is "1" and "0" when the flip-flop is "0". For compatibility with other emulators, bits 7-1 should be set to "0". When bit 0 of "IFF0" is "0" maskable interrupts will be ignored. When bit 0 of "IFF1" is "1" maskable interrupts will be acknowledged and executed. See the document about the Z80 for more information.

3. This byte will be 0, 1 or 2 for the interrupt modes 0, 1 or 2. The interrupt mode is set using the "IM x" instructions. See the document about the Z80 for more information.

4. These registers are from the alternate register set of the Z80.

5. These registers are 16-bit. "low" indicates bits 7..0, "high"indicates bits 15..8.

6. This byte represents the inputs to PPI port A regardless of the input/output setting of this port.

7. This byte represents the inputs to PPI port B regardless of the input/output setting of this port.

8. This byte represents the outputs from port C regardless of the input/output setting of this port.

9. This byte represents the PPI control byte which defines the input/output and mode of each port and not the last value written to this port. For CPCEMU compatibility bit 7 of this byte must be set to "1".

10. This byte in the snapshot represents the selected pen register of the Gate-Array. This byte is the last value written to this port. Bit 7,6,5 should be set to "0".

11. This byte in the snapshot represents the multi-configuration register of the Gate-Array. This byte is the last byte written to this register. For CPCEMU compatibility, bit 7 should be set to "1" and bit 6 and bit 5 set to "0".

12. These bytes are the current palette. For CPCEMU compatibility, these bytes should have bit 7=bit 6=bit 5="0". Bits 4..0 define the colour using the hardware colour code. The colours are stored in the order pen 0, pen1, pen 2,...,pen 15 followed by border colour.

13. This byte represents a ram configuration for a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion, or the built in RAM expansion of the CPC6128 and CPC6128+. Bits 5..0 define the ram expansion code. For CPCEMU compatibility, bit 7 and bit 6 of this byte should be set to "0".

14. This byte in the snapshot represents the index of the currently selected CRTC register. For compatibility with CPCEMU this value should be in the range 0-31.

15. These bytes represent the data of the CRTC's registers.

16. This byte in the snapshot represents the last byte written to the "ROM select" I/O port.

17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.

18. the memory dump can have size 0 in version 3 and in this case all RAM is described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the main 64KB ram immediately followed by the second 64KB ram (if present) (this ram is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion. Note that CPCEMU can only write a 64K or 128K snapshot.

19. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. If standard CPC raster interrupts are used, interrupts are acknowledged and "executed" at the time they are requested, then there will be 6 interrupts executed per screen update cycle.

*CPCEMU uses a simple system to emulate the interrupts. It is assumed there are exactly 6 interrupts per screen update cycle (the interrupts are assumed to occur at a frequency of 300Hz). This byte records the interrupt number in the current screen update cycle. More accurate emulators use the correct interrupt generation method and may ignore this byte. For CPCEMU compatibility, these emulators should set this byte to "0".

*CPCEMU uses a simple system to emulate the screen display. It allows the mode to be changed in each of the 6 interrupts that occur during a single 50Hz/60Hz period. These bytes represent the mode in each of these sections, i.e. the screen modes (0,1 or 2) for the interrupts 0..5. More accurate emulators support changing of the screen mode at any point supported by the Amstrad hardware, these emulators should write "0" for all these bytes.

2. A version 2 snapshot describes Dk'Tronics/Dobbertin compatible RAM in addition to the 64KB base ram. This is a type of RAM expansion which uses the same port and paging mechanism as the extra 64KB inside the 6128. However, the RAM *MUST* be continuous, therefore it's limited to 64KB, 256KB or 512KB additional RAM. The Dk'Tronics silicon disk can't be described on it's own because it's RAM configurations do not start at C4.

The following configurations can be described:
* 64KB base + 64KB extra RAM (e.g. Dk'Tronics 64KB RAM Expansion)
* 64KB base + 256KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion)
* 64KB base + 512KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion & Dk'Tronics 256KB Silicon Disk OR X-MEM OR Symbiface 2 OR other device which provides 512KB)

JavaCPC uses this value to store up to 4MB of RAM. (e.g. [[CPC4MB]]). This type of ram is Dk'Tronics compatible and has multiple banks of 512KB. This value could be used to describe a 1MB or 2MB expansion as long as it is fully Dk'tronics compatible (e.g. rpalmer's 2MB).

== Notes ==

1. This byte in the snapshot represents the last byte written to the printer I/O port (this byte does not include the automatic inversion of the strobe caused by the Amstrad hardware).

2. This register is internal to the CRTC and counts the number of character-lines. The counter counts up. This value is in the range 0-127. (This counter is compared against CRTC register 4).

3. This register is internal to the CRTC and counts the number of raster-lines. The counter counts up. This value is in the range 0-31. (This counter is compared against CRTC register 9).

4. This register is internal to the CRTC and counts the number of raster-lines during vertical adjust. The counter counts up. This value is in the range 0-31. This should be ignored if the CRTC is not "executing" vertical. adjust.(This counter is compared against CRTC register 5).

5. This register is internal to the CRTC and counts the number of characters during horizontal sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" horizontal sync. (This counter is compared against CRTC register 3).

6. This register is internal to the CRTC and counts the number of scan-lines during vertical sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" vertical sync. (This counter is compared against CRTC register 3).

7. These bytes define the internal state of the CRTC. Each bit in these bytes represents a state.

8. When VSYNC is active, the CRTC is "executing" vertical sync, and the vertical sync width counter in the snapshot is used.

9. When HSYNC is active, the CRTC is "executing" horizontal sync width counter in the snapshot is used.

10. When Vertical total adjust is active, the CRTC is "executing" vertical total adjust and the vertical total adjust counter in the snapshot is used.

11. This register is internal to the CRTC and counts the number of characters. This counter counts up. This value is in the range 0-255. (This counter is compared against CRTC register 0).

12. This counter is internal to the GA and counts the number of HSYNCs. This counter is used to generate CPC raster interrupts. This counter counts up. This value is in the range 0-51.

13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).

14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active.

15. This is the current cylinder for each of 4 drives.

16. In WinAPE this counter is reset if a VSYNC occurs which causes the monitor to retrace vertically. This occurs if the VSYNC signal is active and this counter is greater than a threshold set by the V-Hold (normally 295 when V-Hold is 0), or if the counter reaches the maximum value (normally 351 when V-Hold is 0).

17. Since Plus emulation requires more information than simply whether an interrupt is active, this value (as used internally by WinAPE) contains:
* Bit 7 - Gate Array (or PRI) interrupt.
* Bit 6 - DMA Channel 0 interrupt.
* Bit 5 - DMA Channel 1 interrupt.
* Bit 4 - DMA Channel 2 interrupt.

It can be a combination of all or any interrupt sources. Interrupts are executed in the order raster, DMA 2, DMA 1, DMA 0.

Immediately following the memory dump there is optional data which is separated into chunks.

Each chunk of data has a header and this is followed by the data in the chunk. The header has the following format:

{|
|-
| ''Offset (Hex)''
| ''Count''
| ''Description''
|-
| 0
| 4
| Chunk name (note 1)
|-
| 4
| 4
| Chunk data length (note 2)
|}

Notes:

1. The chunks are defined with 4-byte character codes. (e.g. "CPC+"). In this example, the 4-byte character code would be stored in the file as 'C' then 'P' then 'C' then '+'.

2. The "Chunk data length" defines the length of data following the header and does not include the size of the header. This number is stored in little endian format.

3. If a emulator finds a chunk which it does not support then it should skip the chunk and continue with the next chunk in the file. Therefore an emulator author may add emulator specific chunks to the file and it will not prevent the snapshot from being used with other emulators that do not recognise the added chunks.

4. There is not a terminator chunk. The snapshot reader should determine if there are more chunks based on the size of data remaining to be read from the file.

=Version 3 Chunks=

The following chunks are currently defined:

== DSCA,DSCB ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

The DSCA block contains the filename of the disc image inserted into drive A. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

DSCB is similar to DSCA but stores the filename of the disc image inserted into drive B.

== TAPE ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

The TAPE block contains the filename of the tape image inserted. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

== ROMS ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

This block contains a list of filenames for each ROM (and cartridge) that is defined. The length of the block is the length for all strings.

If a ROM is not defined, a single NUL (0) byte is present, otherwise there is a null terminated 8-bit ASCII string.

First in the list is the filename (or internal name) for the cartridge (prefixed with a 'A' character), followed by lower rom and then upper roms 0-31 (WinAPE) or 0-255 (ACE).

WinAPE lists internal ROMs by their internal name (the name listed in the drop down when you configure the roms, e.g. OS464).
ACE always put the actual file name, even for internal ROMs (e.g. System/Firmware_v3.rom).

After the list of the upper ROMs, ACE also put the names of the internal Basic and AMSDOS ROMs.
Then, the presence of the "CartridgeKeepExtROM" let ACE know if the cartridge ROMs should disable installed external upper ROMs or not (depending on user preferences).

NOTE: The selected Multiface ROM is not saved in the snapshot.

== INFO Chunk ==

This chunk is written by No$CPC. It contains an 8-bit ASCII string with the version information for No$CPC.

== MEM0-8 Chunk ==

The MEM0-8 chunks contain at most 64KB of data. The data may be compressed or stored uncompressed. If the size is exactly 65536 bytes the data is uncompressed, otherwise it is compressed. Up to 512KB additional RAM can be stored in a snapshot.

The compression scheme is RLE with 0x0e5 as the control byte.

Data is encoded as:

* <byte> for a single occurrence of a byte (not 0x0e5) (e.g. 0x013)
* 0x0e5,<count>,<byte> for multiple occurances of a byte (e. 0x0e5,0x04,0x013 for 0x013 repeated 4 times)
* 0x0e5,0 for a single 0x0e5 byte (e.g. 0x0e5)

The blocks are:

* MEM0 - main 64KB ram
* MEM1 - c4,c5,c6,c7 configurations (extra 64KB ram in 128KB machines) (256KB Dk'Tronics RAM, X-MEM)
* MEM2 - cc,cd,ce,cf configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM3 - d4,d5,d6,d7 configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM4 - dc,dd,de,df configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM5 - e4,e5,e6,e7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM6 - ec,ed,ee,ef configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM7 - f4,f5,f6,f7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM8 - fc,fd,fe,ff configurations (256KB Dk'Tronics Silicon Disk, X-MEM)

=== Notes ===

1. A snapshot may contain a mix of "standard" memory data (e.g. the data follows the header and is uncompressed) and additional MEM blocks as required.

2. If the snapshot is not compressed, then up to 128KB will be stored as "standard" memory data, the additional RAM stored in MEM2-MEM8 blocks.

3. If the snapshot is compressed, then the "standard" memory data will have 0 size and there will be a MEM0 in addition to the additional memory blocks.

4. Version 3 doesn't require memory to be continuous. A Dk'tronics silicon disk on it's own can be described with this version.

5. WinAPE allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.

6. ACE can save additional memory in snapshots (up to 4MB) using the MX?? chunks.

== MX09-40 Chunk ==

This chunk is supported by ACE.

MX?? chunks allow snapshots to store up to 4160KB ram.

MX?? chunks are following MEM0-8 chunks. They are numbered from 09 to 40 (hexadecimal numbering).
Information are stored compressed like in MEM0-8 chunks.

== BRKC Chunk ==

This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.
The number of stored breakpoints in the chunk is given by the chunk size divided by 216 (the size on one breakpoint data structure).

Allowed additional syntaxes are:
*&, # or 0x for a hexadecimal number.
*% or &x for a binary number.
*AF, BC, HL, IX... for a 16-bit Z80 register.
*A, B, D, IXh, IXl... for an 8-bit Z80 register.

=== Notes ===

1. The sprite data is packed, with two sprite pixels per byte. Bits 7..4 define the first pixel and bits 3..0 define the second pixel.

2. The attributes for each sprite take 8 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| Sprite X (see note)
|-

| 2
| Sprite Y (see note)
|-
| 4
| 1
| Sprite Magnification (see note)
|-
| 5-7
| 3

|}

Note: the Sprite X, Y and magnification are in the same order as the ASIC registers

3. This is a direct copy of the palette in CPC+ ASIC Ram. There are 32 colours each with 2-bytes per colour.

4. These bytes in the snapshot represent the last value written to these ASIC registers.

5. These bytes represent the inputs to the analogue channels.

6. The attributes for each DMA channel take 4 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| DMA Channel address (see note)
|-
| 2
| 1

|-
| 3

| unused (0)
|}

Note: the DMA address and prescalar are in the same order as the ASIC registers.

7 These registers are internal to the CPC+ and define the current DMA operation:

| pause prescalar count (note d)
|}

a. This value represents the number of loops remaining. 0 = none. This count is between 0..0FFF. This counter counts down.

b. This is the Amstrad memory address to loop back to. It is a pointer to the DMA instruction after the last REPEAT instruction.

c. This value represents the pause count and the count is between 0...0FFF. (TO BE CHECKED: down counter? what exactly does it represent)

d. This value represents the pause prescalar count and the count is between 0..FF. (TO BE CHECKED: down counter? what exactly does it represent)

8. This value represents the last value written to this I/O port. Winape uses 8a and not 8b. This value has bits 7,6,5 set to 1,0 and 1 respectively. 8b is in the original specification and is written by both ACE and No$CPC.

9. This value represents the lock status of RMR2. If locked, RMR2 can't be accessed otherwise it can.

10. This value represents the current unlock sequence state.

== BRKS Chunk ==

This chunk is written by WinAPE when some breakpoints are set.
ACE can import breakpoints from this chunk but won't create it (BRKC is used instead).

The chunk contains 1 or more breakpoints.

Each breakpoint has the form:
* 2 bytes: address (LSB first)
* 1 byte: location (0: base 64K RAM, 1: extended RAM)
* 2 bytes: condition (?)

== WABP Chunk ==

This chunk is written by WinAPE when some breakpoints are set.
The exact details are begin worked out.

It seems to be:

4 bytes - number of user breakpoints

Each user breakpoint:

type,
4 byte address

Then, 4 bytes - number of memory breakpoints

Each memory breakpoint:

Then, 4 bytes - number of i/o breakpoints:

Each i/o breakpoint:

2 bytes flags? (6000 read, a400 write)
2 bytes port addr mask
2 bytes port addr
4 bytes counter
4 bytes condition string length, followed by condition string (not null terminated)

== DARS Chunk ==

This chunk is written by WinAPE when some data areas are set.

The number of stored data areas in the chunk is given by the chunk size divided by 10 (the size of one data area data structure).

===Notes===

1. Winape's addressing scheme is 4 bytes. The upper 16-bits effectively define the internal 64KB pages it uses.

== RM00-FF Chunk ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

The RM00-FF chunks contain at most 16KB of data representing the contents of the related external upper ROMs number. The data may be compressed or stored uncompressed. If the size is exactly 16384 bytes the data is uncompressed, otherwise it is compressed. Up to 2MB of external upper ROMs can be stored in a snapshot.

The compression scheme is identical to the one from MEM0-7 chunks.

== LOWR Chunk ==

This chunk was introduced by RASM and is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal firmware ROM contents.

== BASR Chunk ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal Basic ROM contents.

== DOSR Chunk ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal AMSDOS ROM contents.

== CART Chunk ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

It stores the contents of the inserted cartridge ROM. Extended cartridges are also supported.

== PLUG Chunk ==

This chunk is supported by ACE; it is saved only when the related option is enabled.

This chunk stores the names of the plugins which should be enabled for the snapshot.

All names are stored one after the other, in the form of binary strings (first byte containing the plugin name length followed by the the actual string).
The names stored are the actual names of the plugins libraries (e.g. "multiface2.acepansion").

== REMU Chunk ==

This chunk is written RASM and contains information about symbols and breakpoints.
ACE will import informations from this chunk but won't write it (SYMB and BRKC are used instead).

Snapshot

2024-01-02T21:11:43Z

OffseT:

= Snapshot (.SNA) file format =

The format was first defined for the [[CPCEMU|CPCEMU]] emulator but is now widely supported. The format was originally defined by [[Marco Vieth|Marco Vieth]]. Version 3 was defined by [[Ulrich Doewich|Ulrich Doewich]], [[Martin Korth|Martin Korth]], [[Richard Wilson|Richard Wilson]] and [[Kevin Thacker|Kevin Thacker]].

There are 3 versions defined in this document. Version 3 is the most recent and is currently supported by a few of the most recent emulators.

Snapshots produced with [[CPCE|CPCE]] appears to be the most compatible and will run correctly using any emulator.

== Notes ==

1. All multi-byte values are stored in little-endian format (low byte followed by higher bytes).

2. "IFF0" reflects the state of the maskable interrupt (INT). "IFF1" is used to store the state of IFF0 when a non-maskable interrupt (NMI) is executed. Bit 0 of these bytes is significant. For CPCEMU compatibility, these bytes should be set to "1" when the IFF flip-flop is "1" and "0" when the flip-flop is "0". For compatibility with other emulators, bits 7-1 should be set to "0". When bit 0 of "IFF0" is "0" maskable interrupts will be ignored. When bit 0 of "IFF1" is "1" maskable interrupts will be acknowledged and executed. See the document about the Z80 for more information.

3. This byte will be 0, 1 or 2 for the interrupt modes 0, 1 or 2. The interrupt mode is set using the "IM x" instructions. See the document about the Z80 for more information.

4. These registers are from the alternate register set of the Z80.

5. These registers are 16-bit. "low" indicates bits 7..0, "high"indicates bits 15..8.

6. This byte represents the inputs to PPI port A regardless of the input/output setting of this port.

7. This byte represents the inputs to PPI port B regardless of the input/output setting of this port.

8. This byte represents the outputs from port C regardless of the input/output setting of this port.

9. This byte represents the PPI control byte which defines the input/output and mode of each port and not the last value written to this port. For CPCEMU compatibility bit 7 of this byte must be set to "1".

10. This byte in the snapshot represents the selected pen register of the Gate-Array. This byte is the last value written to this port. Bit 7,6,5 should be set to "0".

11. This byte in the snapshot represents the multi-configuration register of the Gate-Array. This byte is the last byte written to this register. For CPCEMU compatibility, bit 7 should be set to "1" and bit 6 and bit 5 set to "0".

12. These bytes are the current palette. For CPCEMU compatibility, these bytes should have bit 7=bit 6=bit 5="0". Bits 4..0 define the colour using the hardware colour code. The colours are stored in the order pen 0, pen1, pen 2,...,pen 15 followed by border colour.

13. This byte represents a ram configuration for a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion, or the built in RAM expansion of the CPC6128 and CPC6128+. Bits 5..0 define the ram expansion code. For CPCEMU compatibility, bit 7 and bit 6 of this byte should be set to "0".

14. This byte in the snapshot represents the index of the currently selected CRTC register. For compatibility with CPCEMU this value should be in the range 0-31.

15. These bytes represent the data of the CRTC's registers.

16. This byte in the snapshot represents the last byte written to the "ROM select" I/O port.

17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.

18. the memory dump can have size 0 in version 3 and in this case all RAM is described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the main 64KB ram immediately followed by the second 64KB ram (if present) (this ram is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion. Note that CPCEMU can only write a 64K or 128K snapshot.

19. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. If standard CPC raster interrupts are used, interrupts are acknowledged and "executed" at the time they are requested, then there will be 6 interrupts executed per screen update cycle.

*CPCEMU uses a simple system to emulate the interrupts. It is assumed there are exactly 6 interrupts per screen update cycle (the interrupts are assumed to occur at a frequency of 300Hz). This byte records the interrupt number in the current screen update cycle. More accurate emulators use the correct interrupt generation method and may ignore this byte. For CPCEMU compatibility, these emulators should set this byte to "0".

*CPCEMU uses a simple system to emulate the screen display. It allows the mode to be changed in each of the 6 interrupts that occur during a single 50Hz/60Hz period. These bytes represent the mode in each of these sections, i.e. the screen modes (0,1 or 2) for the interrupts 0..5. More accurate emulators support changing of the screen mode at any point supported by the Amstrad hardware, these emulators should write "0" for all these bytes.

2. A version 2 snapshot describes Dk'Tronics/Dobbertin compatible RAM in addition to the 64KB base ram. This is a type of RAM expansion which uses the same port and paging mechanism as the extra 64KB inside the 6128. However, the RAM *MUST* be continuous, therefore it's limited to 64KB, 256KB or 512KB additional RAM. The Dk'Tronics silicon disk can't be described on it's own because it's RAM configurations do not start at C4.

The following configurations can be described:
* 64KB base + 64KB extra RAM (e.g. Dk'Tronics 64KB RAM Expansion)
* 64KB base + 256KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion)
* 64KB base + 512KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion & Dk'Tronics 256KB Silicon Disk OR X-MEM OR Symbiface 2 OR other device which provides 512KB)

JavaCPC uses this value to store up to 4MB of RAM. (e.g. [[CPC4MB]]). This type of ram is Dk'Tronics compatible and has multiple banks of 512KB. This value could be used to describe a 1MB or 2MB expansion as long as it is fully Dk'tronics compatible (e.g. rpalmer's 2MB).

== Notes ==

1. This byte in the snapshot represents the last byte written to the printer I/O port (this byte does not include the automatic inversion of the strobe caused by the Amstrad hardware).

2. This register is internal to the CRTC and counts the number of character-lines. The counter counts up. This value is in the range 0-127. (This counter is compared against CRTC register 4).

3. This register is internal to the CRTC and counts the number of raster-lines. The counter counts up. This value is in the range 0-31. (This counter is compared against CRTC register 9).

4. This register is internal to the CRTC and counts the number of raster-lines during vertical adjust. The counter counts up. This value is in the range 0-31. This should be ignored if the CRTC is not "executing" vertical. adjust.(This counter is compared against CRTC register 5).

5. This register is internal to the CRTC and counts the number of characters during horizontal sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" horizontal sync. (This counter is compared against CRTC register 3).

6. This register is internal to the CRTC and counts the number of scan-lines during vertical sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" vertical sync. (This counter is compared against CRTC register 3).

7. These bytes define the internal state of the CRTC. Each bit in these bytes represents a state.

8. When VSYNC is active, the CRTC is "executing" vertical sync, and the vertical sync width counter in the snapshot is used.

9. When HSYNC is active, the CRTC is "executing" horizontal sync width counter in the snapshot is used.

10. When Vertical total adjust is active, the CRTC is "executing" vertical total adjust and the vertical total adjust counter in the snapshot is used.

11. This register is internal to the CRTC and counts the number of characters. This counter counts up. This value is in the range 0-255. (This counter is compared against CRTC register 0).

12. This counter is internal to the GA and counts the number of HSYNCs. This counter is used to generate CPC raster interrupts. This counter counts up. This value is in the range 0-51.

13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).

14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active.

15. This is the current cylinder for each of 4 drives.

16. In WinAPE this counter is reset if a VSYNC occurs which causes the monitor to retrace vertically. This occurs if the VSYNC signal is active and this counter is greater than a threshold set by the V-Hold (normally 295 when V-Hold is 0), or if the counter reaches the maximum value (normally 351 when V-Hold is 0).

17. Since Plus emulation requires more information than simply whether an interrupt is active, this value (as used internally by WinAPE) contains:
* Bit 7 - Gate Array (or PRI) interrupt.
* Bit 6 - DMA Channel 0 interrupt.
* Bit 5 - DMA Channel 1 interrupt.
* Bit 4 - DMA Channel 2 interrupt.

It can be a combination of all or any interrupt sources. Interrupts are executed in the order raster, DMA 2, DMA 1, DMA 0.

Immediately following the memory dump there is optional data which is separated into chunks.

Each chunk of data has a header and this is followed by the data in the chunk. The header has the following format:

{|
|-
| ''Offset (Hex)''
| ''Count''
| ''Description''
|-
| 0
| 4
| Chunk name (note 1)
|-
| 4
| 4
| Chunk data length (note 2)
|}

Notes:

1. The chunks are defined with 4-byte character codes. (e.g. "CPC+"). In this example, the 4-byte character code would be stored in the file as 'C' then 'P' then 'C' then '+'.

2. The "Chunk data length" defines the length of data following the header and does not include the size of the header. This number is stored in little endian format.

3. If a emulator finds a chunk which it does not support then it should skip the chunk and continue with the next chunk in the file. Therefore an emulator author may add emulator specific chunks to the file and it will not prevent the snapshot from being used with other emulators that do not recognise the added chunks.

4. There is not a terminator chunk. The snapshot reader should determine if there are more chunks based on the size of data remaining to be read from the file.

=Version 3 Chunks=

The following chunks are currently defined:

== DSCA,DSCB ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

The DSCA block contains the filename of the disc image inserted into drive A. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

DSCB is similar to DSCA but stores the filename of the disc image inserted into drive B.

== TAPE (ACE) ==

This chunk is saved only when the related option is enabled.

The TAPE block contains the filename of the tape image inserted. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

== ROMS ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

This block contains a list of filenames for each ROM (and cartridge) that is defined. The length of the block is the length for all strings.

If a ROM is not defined, a single NUL (0) byte is present, otherwise there is a null terminated 8-bit ASCII string.

First in the list is the filename (or internal name) for the cartridge (prefixed with a 'A' character), followed by lower rom and then upper roms 0-31 (WinAPE) or 0-255 (ACE).

WinAPE lists internal ROMs by their internal name (the name listed in the drop down when you configure the roms, e.g. OS464).
ACE always put the actual file name, even for internal ROMs (e.g. System/Firmware_v3.rom).

After the list of the upper ROMs, ACE also put the names of the internal Basic and AMSDOS ROMs.
Then, the presence of the "CartridgeKeepExtROM" let ACE know if the cartridge ROMs should disable installed external upper ROMs or not (depending on user preferences).

NOTE: The selected Multiface ROM is not saved in the snapshot.

== INFO Chunk (No$CPC) ==

This chunk is written by No$CPC. It contains an 8-bit ASCII string with the version information for No$CPC.

== MEM0-8 Chunk ==

The MEM0-8 chunks contain at most 64KB of data. The data may be compressed or stored uncompressed. If the size is exactly 65536 bytes the data is uncompressed, otherwise it is compressed. Up to 512KB additional RAM can be stored in a snapshot.

The compression scheme is RLE with 0x0e5 as the control byte.

Data is encoded as:

* <byte> for a single occurrence of a byte (not 0x0e5) (e.g. 0x013)
* 0x0e5,<count>,<byte> for multiple occurances of a byte (e. 0x0e5,0x04,0x013 for 0x013 repeated 4 times)
* 0x0e5,0 for a single 0x0e5 byte (e.g. 0x0e5)

The blocks are:

* MEM0 - main 64KB ram
* MEM1 - c4,c5,c6,c7 configurations (extra 64KB ram in 128KB machines) (256KB Dk'Tronics RAM, X-MEM)
* MEM2 - cc,cd,ce,cf configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM3 - d4,d5,d6,d7 configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM4 - dc,dd,de,df configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM5 - e4,e5,e6,e7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM6 - ec,ed,ee,ef configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM7 - f4,f5,f6,f7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM8 - fc,fd,fe,ff configurations (256KB Dk'Tronics Silicon Disk, X-MEM)

=== Notes ===

1. A snapshot may contain a mix of "standard" memory data (e.g. the data follows the header and is uncompressed) and additional MEM blocks as required.

2. If the snapshot is not compressed, then up to 128KB will be stored as "standard" memory data, the additional RAM stored in MEM2-MEM8 blocks.

3. If the snapshot is compressed, then the "standard" memory data will have 0 size and there will be a MEM0 in addition to the additional memory blocks.

4. Version 3 doesn't require memory to be continuous. A Dk'tronics silicon disk on it's own can be described with this version.

5. WinAPE allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.

6. ACE can save additional memory in snapshots (up to 4MB) using the MX?? chunks.

== MX09-40 Chunk (ACE) ==

MX?? chunks allow snapshots to store up to 4160KB ram.

MX?? chunks are following MEM0-8 chunks. They are numbered from 09 to 40 (hexadecimal numbering).
Information are stored compressed like in MEM0-8 chunks.

== BRKC Chunk (ACE) ==

This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.
The number of stored breakpoints in the chunk is given by the chunk size divided by 216 (the size on one breakpoint data structure).

===Notes===

1. The condition is expressed using ACE syntax (similar to BASIC with AND/OR/XOR/NOT/+/-/=...).
Allowed additional syntaxes are:
*&, # or 0x for a hexadecimal number.
*% or &x for a binary number.
*AF, BC, HL, IX... for a 16-bit Z80 register.
*A, B, D, IXh, IXl... for an 8-bit Z80 register.
*FlagC, FlagNC, FlagM... for a Z80 flag.
*LineCount for the line number.
*LineCycle for the µs count on the current line.
*MemPage for the 64K expansion memory page (0-63).
*MemBankMode for the 16K expansion memory bank paging mode (0-7).
*UpperROMOn for the paging state of the upper ROM.
*UpperROMNum for the selected upper ROM number.
*LowerROMOn for the paging state of the lower ROM.
*LowerROMNum for the selected lower ROM number.
*ASICPageOn for the paging state of the I/O ASIC registers page.

''Example : FlagC AND (HL=DE OR HL=&5000)''

2. The map type determines the memory layout for which the breakpoint is valid.
The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).
* 1: Main RAM. If map bank is 0, then linear main RAM is considered. If map bank is 1, then main RAM from &c000-&ffff mapped as &4000-&7fff is considered. Map page is ignored (always 0).
* 2: Extension RAM. Map bank is the 16K extension bank number (0-3). Map page is the 64K extension page number (0-31).
* 3: Extension ROM. Map bank is the ROM slot id (0-255). Map page is ignored (always 0).
* 4: Firmware ROM. Map bank and page are ignored (always 0).
* 5: Cartridge ROM. Map bank is the 16K ROM bank number (0-31). Map page is ignored (always 0).
* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

== SYMB Chunk (ACE) ==

This chunk is written by ACE when some symbols are declared. When loading a snapshot, the symbols found in this chunk are added to the alreading existing ones.

===Notes===

1. Symbol are (obviously) limited to 255 characters, cannot begin with a number (0-9), and only a limited set of ASCII char is allowed (a-z, A-Z, 0-9, _).
2. The map type determines the memory layout for which the symbol is valid. The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).
* 1: Main RAM. If map bank is 0, then linear main RAM is considered. If map bank is 1, then main RAM from &c000-&ffff mapped as &4000-&7fff is considered. Map page is ignored (always 0).

* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

== CPC+ Chunk ==

This chunk is supported by Arnold, Winape, No$CPC and ACE. Arnold, Winape and ACE will save the block when Plus configuration enabled. No$CPC will save the block if the Plus features have been unlocked.

=== Notes ===

1. The sprite data is packed, with two sprite pixels per byte. Bits 7..4 define the first pixel and bits 3..0 define the second pixel.

2. The attributes for each sprite take 8 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| Sprite X (see note)
|-
| 2
| 2
| Sprite Y (see note)
|-
| 4
| 1
| Sprite Magnification (see note)
|-
| 5-7
| 3
| unused (0)
|}

Note: the Sprite X, Y and magnification are in the same order as the ASIC registers

3. This is a direct copy of the palette in CPC+ ASIC Ram. There are 32 colours each with 2-bytes per colour.

4. These bytes in the snapshot represent the last value written to these ASIC registers.

5. These bytes represent the inputs to the analogue channels.

6. The attributes for each DMA channel take 4 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| DMA Channel address (see note)
|-
| 2
| 1
| DMA Channel prescalar (see note)
|-
| 3
| 1
| unused (0)
|}

Note: the DMA address and prescalar are in the same order as the ASIC registers.

7 These registers are internal to the CPC+ and define the current DMA operation:

|-
| 4
| 2
| pause count (note c)
|-
| 6
| 1
| pause prescalar count (note d)
|}

a. This value represents the number of loops remaining. 0 = none. This count is between 0..0FFF. This counter counts down.

b. This is the Amstrad memory address to loop back to. It is a pointer to the DMA instruction after the last REPEAT instruction.

c. This value represents the pause count and the count is between 0...0FFF. (TO BE CHECKED: down counter? what exactly does it represent)

d. This value represents the pause prescalar count and the count is between 0..FF. (TO BE CHECKED: down counter? what exactly does it represent)

8. This value represents the last value written to this I/O port. Winape uses 8a and not 8b. This value has bits 7,6,5 set to 1,0 and 1 respectively. 8b is in the original specification and is written by both ACE and No$CPC.

9. This value represents the lock status of RMR2. If locked, RMR2 can't be accessed otherwise it can.

10. This value represents the current unlock sequence state.

== BRKS Chunk (WinAPE) ==

This chunk is written by Winape when some breakpoints are set.
ACE can import breakpoints from this chunk.

The chunk contains 1 or more breakpoints.

Each breakpoint has the form:
* 2 bytes: address (LSB first)
* 1 byte: location (0: base 64K RAM, 1: extended RAM)
* 2 bytes: condition (?)

== WABP Chunk (WinAPE) ==

This chunk is written by Winape when some breakpoints are set.
The exact details are begin worked out.

It seems to be:

4 bytes - number of user breakpoints

Each user breakpoint:

type,
4 byte address

Then, 4 bytes - number of memory breakpoints

Each memory breakpoint:

Then, 4 bytes - number of i/o breakpoints:

Each i/o breakpoint:

2 bytes flags? (6000 read, a400 write)
2 bytes port addr mask
2 bytes port addr
4 bytes counter
4 bytes condition string length, followed by condition string (not null terminated)

== DARS Chunk (WinAPE) ==

This chunk is written by Winape when some data areas are set.

The number of stored data areas in the chunk is given by the chunk size divided by 10 (the size of one data area data structure).

===Notes===

1. Winape's addressing scheme is 4 bytes. The upper 16-bits effectively define the internal 64KB pages it uses.

== RM00-FF Chunk ==

This chunk is supported by RASM and ACE; it is saved only when the related option is enabled.

The RM00-FF chunks contain at most 16KB of data representing the contents of the related external upper ROMs number. The data may be compressed or stored uncompressed. If the size is exactly 16384 bytes the data is uncompressed, otherwise it is compressed. Up to 2MB of external upper ROMs can be stored in a snapshot.

The compression scheme is identical to the one from MEM0-7 chunks.

== LOWR Chunk ==

This chunk is supported by RASM and ACE; it is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal firmware ROM contents.

== BASR Chunk (ACE) ==

This chunk is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal Basic ROM contents.

== DOSR Chunk (ACE) ==

This chunk is saved only when the related option is enabled.

It is similar to the RM00-FF chunks but stored the internal AMSDOS ROM contents.

== CART Chunk (ACE) ==

This chunk is saved only when the related option is enabled.

It stores the contents of the inserted cartridge ROM. Extended cartridges are also supported.

== PLUG Chunk (ACE) ==

This chunk stores the names of the plugins which should be enabled for the snapshot.

All names are stored one after the other, in the form of binary strings (first byte containing the plugin name length followed by the the actual string).
The names stored are the actual names of the plugins libraries (e.g. "multiface2.acepansion").

== REMU Chunk ==

This chunk is written RASM and can be read by ACE.

== Notes ==

1. All multi-byte values are stored in little-endian format (low byte followed by higher bytes).

2. "IFF0" reflects the state of the maskable interrupt (INT). "IFF1" is used to store the state of IFF0 when a non-maskable interrupt (NMI) is executed. Bit 0 of these bytes is significant. For CPCEMU compatibility, these bytes should be set to "1" when the IFF flip-flop is "1" and "0" when the flip-flop is "0". For compatibility with other emulators, bits 7-1 should be set to "0". When bit 0 of "IFF0" is "0" maskable interrupts will be ignored. When bit 0 of "IFF1" is "1" maskable interrupts will be acknowledged and executed. See the document about the Z80 for more information.

3. This byte will be 0, 1 or 2 for the interrupt modes 0, 1 or 2. The interrupt mode is set using the "IM x" instructions. See the document about the Z80 for more information.

4. These registers are from the alternate register set of the Z80.

5. These registers are 16-bit. "low" indicates bits 7..0, "high"indicates bits 15..8.

6. This byte represents the inputs to PPI port A regardless of the input/output setting of this port.

7. This byte represents the inputs to PPI port B regardless of the input/output setting of this port.

8. This byte represents the outputs from port C regardless of the input/output setting of this port.

9. This byte represents the PPI control byte which defines the input/output and mode of each port and not the last value written to this port. For CPCEMU compatibility bit 7 of this byte must be set to "1".

10. This byte in the snapshot represents the selected pen register of the Gate-Array. This byte is the last value written to this port. Bit 7,6,5 should be set to "0".

11. This byte in the snapshot represents the multi-configuration register of the Gate-Array. This byte is the last byte written to this register. For CPCEMU compatibility, bit 7 should be set to "1" and bit 6 and bit 5 set to "0".

12. These bytes are the current palette. For CPCEMU compatibility, these bytes should have bit 7=bit 6=bit 5="0". Bits 4..0 define the colour using the hardware colour code. The colours are stored in the order pen 0, pen1, pen 2,...,pen 15 followed by border colour.

13. This byte represents a ram configuration for a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion, or the built in RAM expansion of the CPC6128 and CPC6128+. Bits 5..0 define the ram expansion code. For CPCEMU compatibility, bit 7 and bit 6 of this byte should be set to "0".

14. This byte in the snapshot represents the index of the currently selected CRTC register. For compatibility with CPCEMU this value should be in the range 0-31.

15. These bytes represent the data of the CRTC's registers.

16. This byte in the snapshot represents the last byte written to the "ROM select" I/O port.

17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.

18. the memory dump can have size 0 in version 3 and in this case all RAM is described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the main 64KB ram immediately followed by the second 64KB ram (if present) (this ram is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion. Note that CPCEMU can only write a 64K or 128K snapshot.

19. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. If standard CPC raster interrupts are used, interrupts are acknowledged and "executed" at the time they are requested, then there will be 6 interrupts executed per screen update cycle.

*CPCEMU uses a simple system to emulate the interrupts. It is assumed there are exactly 6 interrupts per screen update cycle (the interrupts are assumed to occur at a frequency of 300Hz). This byte records the interrupt number in the current screen update cycle. More accurate emulators use the correct interrupt generation method and may ignore this byte. For CPCEMU compatibility, these emulators should set this byte to "0".

*CPCEMU uses a simple system to emulate the screen display. It allows the mode to be changed in each of the 6 interrupts that occur during a single 50Hz/60Hz period. These bytes represent the mode in each of these sections, i.e. the screen modes (0,1 or 2) for the interrupts 0..5. More accurate emulators support changing of the screen mode at any point supported by the Amstrad hardware, these emulators should write "0" for all these bytes.

2. A version 2 snapshot describes Dk'Tronics/Dobbertin compatible RAM in addition to the 64KB base ram. This is a type of RAM expansion which uses the same port and paging mechanism as the extra 64KB inside the 6128. However, the RAM *MUST* be continuous, therefore it's limited to 64KB, 256KB or 512KB additional RAM. The Dk'Tronics silicon disk can't be described on it's own because it's RAM configurations do not start at C4.

The following configurations can be described:
* 64KB base + 64KB extra RAM (e.g. Dk'Tronics 64KB RAM Expansion)
* 64KB base + 256KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion)
* 64KB base + 512KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion & Dk'Tronics 256KB Silicon Disk OR X-MEM OR Symbiface 2 OR other device which provides 512KB)

JavaCPC uses this value to store up to 4MB of RAM. (e.g. [[CPC4MB]]). This type of ram is Dk'Tronics compatible and has multiple banks of 512KB. This value could be used to describe a 1MB or 2MB expansion as long as it is fully Dk'tronics compatible (e.g. rpalmer's 2MB).

== Notes ==

1. This byte in the snapshot represents the last byte written to the printer I/O port (this byte does not include the automatic inversion of the strobe caused by the Amstrad hardware).

2. This register is internal to the CRTC and counts the number of character-lines. The counter counts up. This value is in the range 0-127. (This counter is compared against CRTC register 4).

3. This register is internal to the CRTC and counts the number of raster-lines. The counter counts up. This value is in the range 0-31. (This counter is compared against CRTC register 9).

4. This register is internal to the CRTC and counts the number of raster-lines during vertical adjust. The counter counts up. This value is in the range 0-31. This should be ignored if the CRTC is not "executing" vertical. adjust.(This counter is compared against CRTC register 5).

5. This register is internal to the CRTC and counts the number of characters during horizontal sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" horizontal sync. (This counter is compared against CRTC register 3).

6. This register is internal to the CRTC and counts the number of scan-lines during vertical sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" vertical sync. (This counter is compared against CRTC register 3).

7. These bytes define the internal state of the CRTC. Each bit in these bytes represents a state.

8. When VSYNC is active, the CRTC is "executing" vertical sync, and the vertical sync width counter in the snapshot is used.

9. When HSYNC is active, the CRTC is "executing" horizontal sync width counter in the snapshot is used.

10. When Vertical total adjust is active, the CRTC is "executing" vertical total adjust and the vertical total adjust counter in the snapshot is used.

11. This register is internal to the CRTC and counts the number of characters. This counter counts up. This value is in the range 0-255. (This counter is compared against CRTC register 0).

12. This counter is internal to the GA and counts the number of HSYNCs. This counter is used to generate CPC raster interrupts. This counter counts up. This value is in the range 0-51.

13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).

14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active.

15. This is the current cylinder for each of 4 drives.

16. In WinAPE this counter is reset if a VSYNC occurs which causes the monitor to retrace vertically. This occurs if the VSYNC signal is active and this counter is greater than a threshold set by the V-Hold (normally 295 when V-Hold is 0), or if the counter reaches the maximum value (normally 351 when V-Hold is 0).

17. Since Plus emulation requires more information than simply whether an interrupt is active, this value (as used internally by WinAPE) contains:
* Bit 7 - Gate Array (or PRI) interrupt.
* Bit 6 - DMA Channel 0 interrupt.
* Bit 5 - DMA Channel 1 interrupt.
* Bit 4 - DMA Channel 2 interrupt.

It can be a combination of all or any interrupt sources. Interrupts are executed in the order raster, DMA 2, DMA 1, DMA 0.

Immediately following the memory dump there is optional data which is separated into chunks.

Each chunk of data has a header and this is followed by the data in the chunk. The header has the following format:

{|
|-
| ''Offset (Hex)''
| ''Count''
| ''Description''
|-
| 0
| 4
| Chunk name (note 1)
|-
| 4
| 4
| Chunk data length (note 2)
|}

Notes:

1. The chunks are defined with 4-byte character codes. (e.g. "CPC+"). In this example, the 4-byte character code would be stored in the file as 'C' then 'P' then 'C' then '+'.

2. The "Chunk data length" defines the length of data following the header and does not include the size of the header. This number is stored in little endian format.

3. If a emulator finds a chunk which it does not support then it should skip the chunk and continue with the next chunk in the file. Therefore an emulator author may add emulator specific chunks to the file and it will not prevent the snapshot from being used with other emulators that do not recognise the added chunks.

4. There is not a terminator chunk. The snapshot reader should determine if there are more chunks based on the size of data remaining to be read from the file.

=Version 3 Chunks=

The following chunks are currently defined:

== DSCA,DSCB ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

The DSCA block contains the filename of the disc image inserted into drive A. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

DSCB is similar to DSCA but stores the filename of the disc image inserted into drive B.

== TAPE (ACE) ==

This chunk is saved only when the related option is enabled.

The TAPE block contains the filename of the tape image inserted. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

== ROMS ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

This block contains a list of filenames for each ROM (and cartridge) that is defined. The length of the block is the length for all strings.

If a ROM is not defined, a single NUL (0) byte is present, otherwise there is a null terminated 8-bit ASCII string.

First in the list is the filename (or internal name) for the cartridge (prefixed with a 'A' character), followed by lower rom and then upper roms 0-31 (WinAPE) or 0-255 (ACE).

WinAPE lists internal ROMs by their internal name (the name listed in the drop down when you configure the roms, e.g. OS464).
ACE always put the actual file name, even for internal ROMs (e.g. System/Firmware_v3.rom).

After the list of the upper ROMs, ACE also put the names of the internal Basic and AMSDOS ROMs.
Then, the presence of the "CartridgeKeepExtROM" let ACE know if the cartridge ROMs should disable installed external upper ROMs or not (depending on user preferences).

NOTE: The selected Multiface ROM is not saved in the snapshot.

== INFO Chunk (No$CPC) ==

This chunk is written by No$CPC. It contains an 8-bit ASCII string with the version information for No$CPC.

== MEM0-8 Chunk ==

The MEM0-8 chunks contain at most 64KB of data. The data may be compressed or stored uncompressed. If the size is exactly 65536 bytes the data is uncompressed, otherwise it is compressed. Up to 512KB additional RAM can be stored in a snapshot.

The compression scheme is RLE with 0x0e5 as the control byte.

Data is encoded as:

* <byte> for a single occurrence of a byte (not 0x0e5) (e.g. 0x013)
* 0x0e5,<count>,<byte> for multiple occurances of a byte (e. 0x0e5,0x04,0x013 for 0x013 repeated 4 times)
* 0x0e5,0 for a single 0x0e5 byte (e.g. 0x0e5)

The blocks are:

* MEM0 - main 64KB ram
* MEM1 - c4,c5,c6,c7 configurations (extra 64KB ram in 128KB machines) (256KB Dk'Tronics RAM, X-MEM)
* MEM2 - cc,cd,ce,cf configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM3 - d4,d5,d6,d7 configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM4 - dc,dd,de,df configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM5 - e4,e5,e6,e7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM6 - ec,ed,ee,ef configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM7 - f4,f5,f6,f7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM8 - fc,fd,fe,ff configurations (256KB Dk'Tronics Silicon Disk, X-MEM)

=== Notes ===

1. A snapshot may contain a mix of "standard" memory data (e.g. the data follows the header and is uncompressed) and additional MEM blocks as required.

2. If the snapshot is not compressed, then up to 128KB will be stored as "standard" memory data, the additional RAM stored in MEM2-MEM8 blocks.

3. If the snapshot is compressed, then the "standard" memory data will have 0 size and there will be a MEM0 in addition to the additional memory blocks.

4. Version 3 doesn't require memory to be continuous. A Dk'tronics silicon disk on it's own can be described with this version.

5. WinAPE allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.

6. ACE can save additional memory in snapshots (up to 4MB) using the MX?? chunks.

== MX09-40 Chunk (ACE) ==

MX?? chunks allow snapshots to store up to 4160KB ram.

MX?? chunks are following MEM0-8 chunks. They are numbered from 09 to 40 (hexadecimal numbering).
Information are stored compressed like in MEM0-8 chunks.

== BRKC Chunk (ACE) ==

This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.
The number of stored breakpoints in the chunk is given by the chunk size divided by 216 (the size on one breakpoint data structure).

Allowed additional syntaxes are:
*&, # or 0x for a hexadecimal number.
*% or &x for a binary number.
*AF, BC, HL, IX... for a 16-bit Z80 register.
*A, B, D, IXh, IXl... for an 8-bit Z80 register.

*LineCount for the line number.
*LineCycle for the µs count on the current line.
*MemPage for the 64K expansion memory page (0-63).

*ASICPageOn for the paging state of the I/O ASIC registers page.

''Example : FlagC AND (HL=DE OR HL=&5000)''

2. The map type determines the memory layout for which the breakpoint is valid.
The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:

=== Notes ===

1. The sprite data is packed, with two sprite pixels per byte. Bits 7..4 define the first pixel and bits 3..0 define the second pixel.

2. The attributes for each sprite take 8 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| Sprite X (see note)

| 2
| Sprite Y (see note)
|-
| 4
| 1
| Sprite Magnification (see note)
|-
| 5-7
| 3
| unused (0)
|}

Note: the Sprite X, Y and magnification are in the same order as the ASIC registers

3. This is a direct copy of the palette in CPC+ ASIC Ram. There are 32 colours each with 2-bytes per colour.

4. These bytes in the snapshot represent the last value written to these ASIC registers.

5. These bytes represent the inputs to the analogue channels.

6. The attributes for each DMA channel take 4 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| DMA Channel address (see note)
|-
| 2
| 1
| DMA Channel prescalar (see note)
|-
| 3
| 1
| unused (0)
|}

Note: the DMA address and prescalar are in the same order as the ASIC registers.

7 These registers are internal to the CPC+ and define the current DMA operation:

| 2
| loop address (note b)
|-
| 4
| 2
| pause count (note c)
|-
| 6
| 1
| pause prescalar count (note d)
|}

a. This value represents the number of loops remaining. 0 = none. This count is between 0..0FFF. This counter counts down.

b. This is the Amstrad memory address to loop back to. It is a pointer to the DMA instruction after the last REPEAT instruction.

c. This value represents the pause count and the count is between 0...0FFF. (TO BE CHECKED: down counter? what exactly does it represent)

d. This value represents the pause prescalar count and the count is between 0..FF. (TO BE CHECKED: down counter? what exactly does it represent)

8. This value represents the last value written to this I/O port. Winape uses 8a and not 8b. This value has bits 7,6,5 set to 1,0 and 1 respectively. 8b is in the original specification and is written by both ACE and No$CPC.

9. This value represents the lock status of RMR2. If locked, RMR2 can't be accessed otherwise it can.

10. This value represents the current unlock sequence state.

== WABP Chunk (Winape) ==

This chunk is written by Winape when some breakpoints are set.
The exact details are begin worked out.

It seems to be:

4 bytes - number of user breakpoints

Each user breakpoint:

type,
4 byte address

Then, 4 bytes - number of memory breakpoints

Each memory breakpoint:

Then, 4 bytes - number of i/o breakpoints:

Each i/o breakpoint:

2 bytes flags? (6000 read, a400 write)
2 bytes port addr mask
2 bytes port addr
4 bytes counter
4 bytes condition string length, followed by condition string (not null terminated)

== DARS Chunk (Winape) ==

This chunk is written by Winape when some data areas are set.

The number of stored data areas in the chunk is given by the chunk size divided by 10 (the size of one data area data structure).

OffseT: /* SYMB Chunk (ACE) */

= Snapshot (.SNA) file format =

The format was first defined for the [[CPCEMU|CPCEMU]] emulator but is now widely supported. The format was originally defined by [[Marco Vieth|Marco Vieth]]. Version 3 was defined by [[Ulrich Doewich|Ulrich Doewich]], [[Martin Korth|Martin Korth]], [[Richard Wilson|Richard Wilson]] and [[Kevin Thacker|Kevin Thacker]].

There are 3 versions defined in this document. Version 3 is the most recent and is currently supported by a few of the most recent emulators.

Snapshots produced with [[CPCE|CPCE]] appears to be the most compatible and will run correctly using any emulator.

== Notes ==

1. All multi-byte values are stored in little-endian format (low byte followed by higher bytes).

2. "IFF0" reflects the state of the maskable interrupt (INT). "IFF1" is used to store the state of IFF0 when a non-maskable interrupt (NMI) is executed. Bit 0 of these bytes is significant. For CPCEMU compatibility, these bytes should be set to "1" when the IFF flip-flop is "1" and "0" when the flip-flop is "0". For compatibility with other emulators, bits 7-1 should be set to "0". When bit 0 of "IFF0" is "0" maskable interrupts will be ignored. When bit 0 of "IFF1" is "1" maskable interrupts will be acknowledged and executed. See the document about the Z80 for more information.

3. This byte will be 0, 1 or 2 for the interrupt modes 0, 1 or 2. The interrupt mode is set using the "IM x" instructions. See the document about the Z80 for more information.

4. These registers are from the alternate register set of the Z80.

5. These registers are 16-bit. "low" indicates bits 7..0, "high"indicates bits 15..8.

6. This byte represents the inputs to PPI port A regardless of the input/output setting of this port.

7. This byte represents the inputs to PPI port B regardless of the input/output setting of this port.

8. This byte represents the outputs from port C regardless of the input/output setting of this port.

9. This byte represents the PPI control byte which defines the input/output and mode of each port and not the last value written to this port. For CPCEMU compatibility bit 7 of this byte must be set to "1".

10. This byte in the snapshot represents the selected pen register of the Gate-Array. This byte is the last value written to this port. Bit 7,6,5 should be set to "0".

11. This byte in the snapshot represents the multi-configuration register of the Gate-Array. This byte is the last byte written to this register. For CPCEMU compatibility, bit 7 should be set to "1" and bit 6 and bit 5 set to "0".

12. These bytes are the current palette. For CPCEMU compatibility, these bytes should have bit 7=bit 6=bit 5="0". Bits 4..0 define the colour using the hardware colour code. The colours are stored in the order pen 0, pen1, pen 2,...,pen 15 followed by border colour.

13. This byte represents a ram configuration for a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion, or the built in RAM expansion of the CPC6128 and CPC6128+. Bits 5..0 define the ram expansion code. For CPCEMU compatibility, bit 7 and bit 6 of this byte should be set to "0".

14. This byte in the snapshot represents the index of the currently selected CRTC register. For compatibility with CPCEMU this value should be in the range 0-31.

15. These bytes represent the data of the CRTC's registers.

16. This byte in the snapshot represents the last byte written to the "ROM select" I/O port.

17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.

18. the memory dump can have size 0 in version 3 and in this case all RAM is described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the main 64KB ram immediately followed by the second 64KB ram (if present) (this ram is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion. Note that CPCEMU can only write a 64K or 128K snapshot.

19. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. If standard CPC raster interrupts are used, interrupts are acknowledged and "executed" at the time they are requested, then there will be 6 interrupts executed per screen update cycle.

*CPCEMU uses a simple system to emulate the interrupts. It is assumed there are exactly 6 interrupts per screen update cycle (the interrupts are assumed to occur at a frequency of 300Hz). This byte records the interrupt number in the current screen update cycle. More accurate emulators use the correct interrupt generation method and may ignore this byte. For CPCEMU compatibility, these emulators should set this byte to "0".

*CPCEMU uses a simple system to emulate the screen display. It allows the mode to be changed in each of the 6 interrupts that occur during a single 50Hz/60Hz period. These bytes represent the mode in each of these sections, i.e. the screen modes (0,1 or 2) for the interrupts 0..5. More accurate emulators support changing of the screen mode at any point supported by the Amstrad hardware, these emulators should write "0" for all these bytes.

2. A version 2 snapshot describes Dk'Tronics/Dobbertin compatible RAM in addition to the 64KB base ram. This is a type of RAM expansion which uses the same port and paging mechanism as the extra 64KB inside the 6128. However, the RAM *MUST* be continuous, therefore it's limited to 64KB, 256KB or 512KB additional RAM. The Dk'Tronics silicon disk can't be described on it's own because it's RAM configurations do not start at C4.

The following configurations can be described:
* 64KB base + 64KB extra RAM (e.g. Dk'Tronics 64KB RAM Expansion)
* 64KB base + 256KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion)
* 64KB base + 512KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion & Dk'Tronics 256KB Silicon Disk OR X-MEM OR Symbiface 2 OR other device which provides 512KB)

JavaCPC uses this value to store up to 4MB of RAM. (e.g. [[CPC4MB]]). This type of ram is Dk'Tronics compatible and has multiple banks of 512KB. This value could be used to describe a 1MB or 2MB expansion as long as it is fully Dk'tronics compatible (e.g. rpalmer's 2MB).

== Notes ==

1. This byte in the snapshot represents the last byte written to the printer I/O port (this byte does not include the automatic inversion of the strobe caused by the Amstrad hardware).

2. This register is internal to the CRTC and counts the number of character-lines. The counter counts up. This value is in the range 0-127. (This counter is compared against CRTC register 4).

3. This register is internal to the CRTC and counts the number of raster-lines. The counter counts up. This value is in the range 0-31. (This counter is compared against CRTC register 9).

4. This register is internal to the CRTC and counts the number of raster-lines during vertical adjust. The counter counts up. This value is in the range 0-31. This should be ignored if the CRTC is not "executing" vertical. adjust.(This counter is compared against CRTC register 5).

5. This register is internal to the CRTC and counts the number of characters during horizontal sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" horizontal sync. (This counter is compared against CRTC register 3).

6. This register is internal to the CRTC and counts the number of scan-lines during vertical sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" vertical sync. (This counter is compared against CRTC register 3).

7. These bytes define the internal state of the CRTC. Each bit in these bytes represents a state.

8. When VSYNC is active, the CRTC is "executing" vertical sync, and the vertical sync width counter in the snapshot is used.

9. When HSYNC is active, the CRTC is "executing" horizontal sync width counter in the snapshot is used.

10. When Vertical total adjust is active, the CRTC is "executing" vertical total adjust and the vertical total adjust counter in the snapshot is used.

11. This register is internal to the CRTC and counts the number of characters. This counter counts up. This value is in the range 0-255. (This counter is compared against CRTC register 0).

12. This counter is internal to the GA and counts the number of HSYNCs. This counter is used to generate CPC raster interrupts. This counter counts up. This value is in the range 0-51.

13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).

14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active.

15. This is the current cylinder for each of 4 drives.

16. In WinAPE this counter is reset if a VSYNC occurs which causes the monitor to retrace vertically. This occurs if the VSYNC signal is active and this counter is greater than a threshold set by the V-Hold (normally 295 when V-Hold is 0), or if the counter reaches the maximum value (normally 351 when V-Hold is 0).

17. Since Plus emulation requires more information than simply whether an interrupt is active, this value (as used internally by WinAPE) contains:
* Bit 7 - Gate Array (or PRI) interrupt.
* Bit 6 - DMA Channel 0 interrupt.
* Bit 5 - DMA Channel 1 interrupt.
* Bit 4 - DMA Channel 2 interrupt.

It can be a combination of all or any interrupt sources. Interrupts are executed in the order raster, DMA 2, DMA 1, DMA 0.

Immediately following the memory dump there is optional data which is separated into chunks.

Each chunk of data has a header and this is followed by the data in the chunk. The header has the following format:

{|
|-
| ''Offset (Hex)''
| ''Count''
| ''Description''
|-
| 0
| 4
| Chunk name (note 1)
|-
| 4
| 4
| Chunk data length (note 2)
|}

Notes:

1. The chunks are defined with 4-byte character codes. (e.g. "CPC+"). In this example, the 4-byte character code would be stored in the file as 'C' then 'P' then 'C' then '+'.

2. The "Chunk data length" defines the length of data following the header and does not include the size of the header. This number is stored in little endian format.

3. If a emulator finds a chunk which it does not support then it should skip the chunk and continue with the next chunk in the file. Therefore an emulator author may add emulator specific chunks to the file and it will not prevent the snapshot from being used with other emulators that do not recognise the added chunks.

4. There is not a terminator chunk. The snapshot reader should determine if there are more chunks based on the size of data remaining to be read from the file.

=Version 3 Chunks=

The following chunks are currently defined:

== DSCA,DSCB ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

The DSCA block contains the filename of the disc image inserted into drive A. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

DSCB is similar to DSCA but stores the filename of the disc image inserted into drive B.

== TAPE (ACE) ==

This chunk is saved only when the related option is enabled.

The TAPE block contains the filename of the tape image inserted. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

== ROMS ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

This block contains a list of filenames for each ROM (and cartridge) that is defined. The length of the block is the length for all strings.

If a ROM is not defined, a single NUL (0) byte is present, otherwise there is a null terminated 8-bit ASCII string.

First in the list is the filename (or internal name) for the cartridge (prefixed with a 'A' character), followed by lower rom and then upper roms 0-31 (WinAPE) or 0-255 (ACE).

Internal ROMs are listed by their internal name (the name listed in the drop down when you configure the roms) (e.g. OS464).

NOTE: The selected Multiface ROM is not saved in the snapshot.

== INFO Chunk (No$CPC) ==

This chunk is written by No$CPC. It contains an 8-bit ASCII string with the version information for No$CPC.

== MEM0-8 Chunk ==

The MEM0-8 chunks contain at most 64KB of data. The data may be compressed or stored uncompressed. If the size is exactly 65536 bytes the data is uncompressed, otherwise it is compressed. Up to 512KB additional RAM can be stored in a snapshot.

The compression scheme is RLE with 0x0e5 as the control byte.

Data is encoded as:

* <byte> for a single occurrence of a byte (not 0x0e5) (e.g. 0x013)
* 0x0e5,<count>,<byte> for multiple occurances of a byte (e. 0x0e5,0x04,0x013 for 0x013 repeated 4 times)
* 0x0e5,0 for a single 0x0e5 byte (e.g. 0x0e5)

The blocks are:

* MEM0 - main 64KB ram
* MEM1 - c4,c5,c6,c7 configurations (extra 64KB ram in 128KB machines) (256KB Dk'Tronics RAM, X-MEM)
* MEM2 - cc,cd,ce,cf configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM3 - d4,d5,d6,d7 configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM4 - dc,dd,de,df configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM5 - e4,e5,e6,e7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM6 - ec,ed,ee,ef configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM7 - f4,f5,f6,f7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM8 - fc,fd,fe,ff configurations (256KB Dk'Tronics Silicon Disk, X-MEM)

=== Notes ===

1. A snapshot may contain a mix of "standard" memory data (e.g. the data follows the header and is uncompressed) and additional MEM blocks as required.

2. If the snapshot is not compressed, then up to 128KB will be stored as "standard" memory data, the additional RAM stored in MEM2-MEM8 blocks.

3. If the snapshot is compressed, then the "standard" memory data will have 0 size and there will be a MEM0 in addition to the additional memory blocks.

4. Version 3 doesn't require memory to be continuous. A Dk'tronics silicon disk on it's own can be described with this version.

5. WinAPE allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.

6. ACE can save additional memory in snapshots (up to 4MB) using the MX?? chunks.

== MX09-40 Chunk (ACE) ==

MX?? chunks allow snapshots to store up to 4160KB ram.

MX?? chunks are following MEM0-8 chunks. They are numbered from 09 to 40 (hexadecimal numbering).
Information are stored compressed like in MEM0-8 chunks.

== BRKC Chunk (ACE) ==

This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.
The number of stored breakpoints in the chunk is given by the chunk size divided by 216 (the size on one breakpoint data structure).

===Notes===

1. The condition is expressed using ACE syntax (similar to BASIC with AND/OR/XOR/NOT/+/-/=...).
Allowed additional syntaxes are:
*&, # or 0x for a hexadecimal number.
*% or &x for a binary number.
*AF, BC, HL, IX... for a 16-bit Z80 register.
*A, B, D, IXh, IXl... for an 8-bit Z80 register.
*FlagC, FlagNC, FlagM... for a Z80 flag.
*LineCount for the line number.
*LineCycle for the µs count on the current line.
*MemPage for the 64K expansion memory page (0-63).
*MemBankMode for the 16K expansion memory bank paging mode (0-7).
*UpperROMOn for the paging state of the upper ROM.
*UpperROMNum for the selected upper ROM number.
*LowerROMOn for the paging state of the lower ROM.
*LowerROMNum for the selected lower ROM number.
*ASICPageOn for the paging state of the I/O ASIC registers page.

''Example : FlagC AND (HL=DE OR HL=&5000)''

2. The map type determines the memory layout for which the breakpoint is valid.
The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).
* 1: Main RAM. If map bank is 0, then linear main RAM is considered. If map bank is 1, then main RAM from &c000-&ffff mapped as &4000-&7fff is considered. Map page is ignored (always 0).
* 2: Extension RAM. Map bank is the 16K extension bank number (0-3). Map page is the 64K extension page number (0-31).
* 3: Extension ROM. Map bank is the ROM slot id (0-255). Map page is ignored (always 0).
* 4: Firmware ROM. Map bank and page are ignored (always 0).
* 5: Cartridge ROM. Map bank is the 16K ROM bank number (0-31). Map page is ignored (always 0).
* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

=== Notes ===

1. The sprite data is packed, with two sprite pixels per byte. Bits 7..4 define the first pixel and bits 3..0 define the second pixel.

2. The attributes for each sprite take 8 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| Sprite X (see note)
|-

| 2
| Sprite Y (see note)
|-
| 4
| 1
| Sprite Magnification (see note)
|-
| 5-7
| 3
| unused (0)
|}

Note: the Sprite X, Y and magnification are in the same order as the ASIC registers

3. This is a direct copy of the palette in CPC+ ASIC Ram. There are 32 colours each with 2-bytes per colour.

4. These bytes in the snapshot represent the last value written to these ASIC registers.

5. These bytes represent the inputs to the analogue channels.

6. The attributes for each DMA channel take 4 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| DMA Channel address (see note)
|-
| 2
| 1
| DMA Channel prescalar (see note)
|-
| 3
| 1
| unused (0)
|}

Note: the DMA address and prescalar are in the same order as the ASIC registers.

7 These registers are internal to the CPC+ and define the current DMA operation:

|-
| 4
| 2
| pause count (note c)
|-
| 6
| 1
| pause prescalar count (note d)
|}

a. This value represents the number of loops remaining. 0 = none. This count is between 0..0FFF. This counter counts down.

b. This is the Amstrad memory address to loop back to. It is a pointer to the DMA instruction after the last REPEAT instruction.

c. This value represents the pause count and the count is between 0...0FFF. (TO BE CHECKED: down counter? what exactly does it represent)

d. This value represents the pause prescalar count and the count is between 0..FF. (TO BE CHECKED: down counter? what exactly does it represent)

8. This value represents the last value written to this I/O port. Winape uses 8a and not 8b. This value has bits 7,6,5 set to 1,0 and 1 respectively. 8b is in the original specification and is written by both ACE and No$CPC.

9. This value represents the lock status of RMR2. If locked, RMR2 can't be accessed otherwise it can.

10. This value represents the current unlock sequence state.

== WABP Chunk (Winape) ==

This chunk is written by Winape when some breakpoints are set.
The exact details are begin worked out.

It seems to be:

4 bytes - number of user breakpoints

Each user breakpoint:

type,
4 byte address

Then, 4 bytes - number of memory breakpoints

Each memory breakpoint:

Then, 4 bytes - number of i/o breakpoints:

Each i/o breakpoint:

2 bytes flags? (6000 read, a400 write)
2 bytes port addr mask
2 bytes port addr
4 bytes counter
4 bytes condition string length, followed by condition string (not null terminated)

== DARS Chunk (Winape) ==

This chunk is written by Winape when some data areas are set.

The number of stored data areas in the chunk is given by the chunk size divided by 10 (the size of one data area data structure).

OffseT: /* BRKC Chunk (ACE) */

= Snapshot (.SNA) file format =

The format was first defined for the [[CPCEMU|CPCEMU]] emulator but is now widely supported. The format was originally defined by [[Marco Vieth|Marco Vieth]]. Version 3 was defined by [[Ulrich Doewich|Ulrich Doewich]], [[Martin Korth|Martin Korth]], [[Richard Wilson|Richard Wilson]] and [[Kevin Thacker|Kevin Thacker]].

There are 3 versions defined in this document. Version 3 is the most recent and is currently supported by a few of the most recent emulators.

Snapshots produced with [[CPCE|CPCE]] appears to be the most compatible and will run correctly using any emulator.

== Notes ==

1. All multi-byte values are stored in little-endian format (low byte followed by higher bytes).

2. "IFF0" reflects the state of the maskable interrupt (INT). "IFF1" is used to store the state of IFF0 when a non-maskable interrupt (NMI) is executed. Bit 0 of these bytes is significant. For CPCEMU compatibility, these bytes should be set to "1" when the IFF flip-flop is "1" and "0" when the flip-flop is "0". For compatibility with other emulators, bits 7-1 should be set to "0". When bit 0 of "IFF0" is "0" maskable interrupts will be ignored. When bit 0 of "IFF1" is "1" maskable interrupts will be acknowledged and executed. See the document about the Z80 for more information.

3. This byte will be 0, 1 or 2 for the interrupt modes 0, 1 or 2. The interrupt mode is set using the "IM x" instructions. See the document about the Z80 for more information.

4. These registers are from the alternate register set of the Z80.

5. These registers are 16-bit. "low" indicates bits 7..0, "high"indicates bits 15..8.

6. This byte represents the inputs to PPI port A regardless of the input/output setting of this port.

7. This byte represents the inputs to PPI port B regardless of the input/output setting of this port.

8. This byte represents the outputs from port C regardless of the input/output setting of this port.

9. This byte represents the PPI control byte which defines the input/output and mode of each port and not the last value written to this port. For CPCEMU compatibility bit 7 of this byte must be set to "1".

10. This byte in the snapshot represents the selected pen register of the Gate-Array. This byte is the last value written to this port. Bit 7,6,5 should be set to "0".

11. This byte in the snapshot represents the multi-configuration register of the Gate-Array. This byte is the last byte written to this register. For CPCEMU compatibility, bit 7 should be set to "1" and bit 6 and bit 5 set to "0".

12. These bytes are the current palette. For CPCEMU compatibility, these bytes should have bit 7=bit 6=bit 5="0". Bits 4..0 define the colour using the hardware colour code. The colours are stored in the order pen 0, pen1, pen 2,...,pen 15 followed by border colour.

13. This byte represents a ram configuration for a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion, or the built in RAM expansion of the CPC6128 and CPC6128+. Bits 5..0 define the ram expansion code. For CPCEMU compatibility, bit 7 and bit 6 of this byte should be set to "0".

14. This byte in the snapshot represents the index of the currently selected CRTC register. For compatibility with CPCEMU this value should be in the range 0-31.

15. These bytes represent the data of the CRTC's registers.

16. This byte in the snapshot represents the last byte written to the "ROM select" I/O port.

17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.

18. the memory dump can have size 0 in version 3 and in this case all RAM is described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the main 64KB ram immediately followed by the second 64KB ram (if present) (this ram is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion. Note that CPCEMU can only write a 64K or 128K snapshot.

19. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. If standard CPC raster interrupts are used, interrupts are acknowledged and "executed" at the time they are requested, then there will be 6 interrupts executed per screen update cycle.

*CPCEMU uses a simple system to emulate the interrupts. It is assumed there are exactly 6 interrupts per screen update cycle (the interrupts are assumed to occur at a frequency of 300Hz). This byte records the interrupt number in the current screen update cycle. More accurate emulators use the correct interrupt generation method and may ignore this byte. For CPCEMU compatibility, these emulators should set this byte to "0".

*CPCEMU uses a simple system to emulate the screen display. It allows the mode to be changed in each of the 6 interrupts that occur during a single 50Hz/60Hz period. These bytes represent the mode in each of these sections, i.e. the screen modes (0,1 or 2) for the interrupts 0..5. More accurate emulators support changing of the screen mode at any point supported by the Amstrad hardware, these emulators should write "0" for all these bytes.

2. A version 2 snapshot describes Dk'Tronics/Dobbertin compatible RAM in addition to the 64KB base ram. This is a type of RAM expansion which uses the same port and paging mechanism as the extra 64KB inside the 6128. However, the RAM *MUST* be continuous, therefore it's limited to 64KB, 256KB or 512KB additional RAM. The Dk'Tronics silicon disk can't be described on it's own because it's RAM configurations do not start at C4.

The following configurations can be described:
* 64KB base + 64KB extra RAM (e.g. Dk'Tronics 64KB RAM Expansion)
* 64KB base + 256KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion)
* 64KB base + 512KB extra RAM (e.g. Dk'Tronics 256KB RAM Expansion & Dk'Tronics 256KB Silicon Disk OR X-MEM OR Symbiface 2 OR other device which provides 512KB)

JavaCPC uses this value to store up to 4MB of RAM. (e.g. [[CPC4MB]]). This type of ram is Dk'Tronics compatible and has multiple banks of 512KB. This value could be used to describe a 1MB or 2MB expansion as long as it is fully Dk'tronics compatible (e.g. rpalmer's 2MB).

3. JavaCPC uses e0-ff to store an emulator ID (see snapshot V3 for more details)

== Notes ==

1. This byte in the snapshot represents the last byte written to the printer I/O port (this byte does not include the automatic inversion of the strobe caused by the Amstrad hardware).

2. This register is internal to the CRTC and counts the number of character-lines. The counter counts up. This value is in the range 0-127. (This counter is compared against CRTC register 4).

3. This register is internal to the CRTC and counts the number of raster-lines. The counter counts up. This value is in the range 0-31. (This counter is compared against CRTC register 9).

4. This register is internal to the CRTC and counts the number of raster-lines during vertical adjust. The counter counts up. This value is in the range 0-31. This should be ignored if the CRTC is not "executing" vertical. adjust.(This counter is compared against CRTC register 5).

5. This register is internal to the CRTC and counts the number of characters during horizontal sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" horizontal sync. (This counter is compared against CRTC register 3).

6. This register is internal to the CRTC and counts the number of scan-lines during vertical sync. This counter counts up. This value is in the range 0-16. This should be ignored if the CRTC is not "executing" vertical sync. (This counter is compared against CRTC register 3).

7. These bytes define the internal state of the CRTC. Each bit in these bytes represents a state.

8. When VSYNC is active, the CRTC is "executing" vertical sync, and the vertical sync width counter in the snapshot is used.

9. When HSYNC is active, the CRTC is "executing" horizontal sync width counter in the snapshot is used.

10. When Vertical total adjust is active, the CRTC is "executing" vertical total adjust and the vertical total adjust counter in the snapshot is used.

11. This register is internal to the CRTC and counts the number of characters. This counter counts up. This value is in the range 0-255. (This counter is compared against CRTC register 0).

12. This counter is internal to the GA and counts the number of HSYNCs. This counter is used to generate CPC raster interrupts. This counter counts up. This value is in the range 0-51.

13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).

14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active.

15. This is the current cylinder for each of 4 drives.

16. In WinAPE this counter is reset if a VSYNC occurs which causes the monitor to retrace vertically. This occurs if the VSYNC signal is active and this counter is greater than a threshold set by the V-Hold (normally 295 when V-Hold is 0), or if the counter reaches the maximum value (normally 351 when V-Hold is 0).

17. Since Plus emulation requires more information than simply whether an interrupt is active, this value (as used internally by WinAPE) contains:
* Bit 7 - Gate Array (or PRI) interrupt.
* Bit 6 - DMA Channel 0 interrupt.
* Bit 5 - DMA Channel 1 interrupt.
* Bit 4 - DMA Channel 2 interrupt.

It can be a combination of all or any interrupt sources. Interrupts are executed in the order raster, DMA 2, DMA 1, DMA 0.

Immediately following the memory dump there is optional data which is separated into chunks.

Each chunk of data has a header and this is followed by the data in the chunk. The header has the following format:

{|
|-
| ''Offset (Hex)''
| ''Count''
| ''Description''
|-
| 0
| 4
| Chunk name (note 1)
|-
| 4
| 4
| Chunk data length (note 2)
|}

Notes:

1. The chunks are defined with 4-byte character codes. (e.g. "CPC+"). In this example, the 4-byte character code would be stored in the file as 'C' then 'P' then 'C' then '+'.

2. The "Chunk data length" defines the length of data following the header and does not include the size of the header. This number is stored in little endian format.

3. If a emulator finds a chunk which it does not support then it should skip the chunk and continue with the next chunk in the file. Therefore an emulator author may add emulator specific chunks to the file and it will not prevent the snapshot from being used with other emulators that do not recognise the added chunks.

4. There is not a terminator chunk. The snapshot reader should determine if there are more chunks based on the size of data remaining to be read from the file.

=Version 3 Chunks=

The following chunks are currently defined:

== DSCA,DSCB ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

The DSCA block contains the filename of the disc image inserted into drive A. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

DSCB is similar to DSCA but stores the filename of the disc image inserted into drive B.

== TAPE (ACE) ==

This chunk is saved only when the related option is enabled.

The TAPE block contains the filename of the tape image inserted. The filename is stored as 8-bit ASCII (any Unicode characters with codes 0x100 or above will be translated to ? and therefore filenames with these characters can't be stored in Snapshots). The length of the block is the length of the filename in bytes.

== ROMS ==

This chunk is supported by WinAPE and ACE; it is saved only when the related option is enabled.

This block contains a list of filenames for each ROM (and cartridge) that is defined. The length of the block is the length for all strings.

If a ROM is not defined, a single NUL (0) byte is present, otherwise there is a null terminated 8-bit ASCII string.

First in the list is the filename (or internal name) for the cartridge (prefixed with a 'A' character), followed by lower rom and then upper roms 0-31 (WinAPE) or 0-255 (ACE).

Internal ROMs are listed by their internal name (the name listed in the drop down when you configure the roms) (e.g. OS464).

NOTE: The selected Multiface ROM is not saved in the snapshot.

== INFO Chunk (No$CPC) ==

This chunk is written by No$CPC. It contains an 8-bit ASCII string with the version information for No$CPC.

== MEM0-8 Chunk ==

The MEM0-8 chunks contain at most 64KB of data. The data may be compressed or stored uncompressed. If the size is exactly 65536 bytes the data is uncompressed, otherwise it is compressed. Up to 512KB additional RAM can be stored in a snapshot.

The compression scheme is RLE with 0x0e5 as the control byte.

Data is encoded as:

* <byte> for a single occurrence of a byte (not 0x0e5) (e.g. 0x013)
* 0x0e5,<count>,<byte> for multiple occurances of a byte (e. 0x0e5,0x04,0x013 for 0x013 repeated 4 times)
* 0x0e5,0 for a single 0x0e5 byte (e.g. 0x0e5)

The blocks are:

* MEM0 - main 64KB ram
* MEM1 - c4,c5,c6,c7 configurations (extra 64KB ram in 128KB machines) (256KB Dk'Tronics RAM, X-MEM)
* MEM2 - cc,cd,ce,cf configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM3 - d4,d5,d6,d7 configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM4 - dc,dd,de,df configurations (256KB Dk'Tronics RAM, X-MEM)
* MEM5 - e4,e5,e6,e7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM6 - ec,ed,ee,ef configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM7 - f4,f5,f6,f7 configurations (256KB Dk'Tronics Silicon Disk, X-MEM)
* MEM8 - fc,fd,fe,ff configurations (256KB Dk'Tronics Silicon Disk, X-MEM)

=== Notes ===

1. A snapshot may contain a mix of "standard" memory data (e.g. the data follows the header and is uncompressed) and additional MEM blocks as required.

2. If the snapshot is not compressed, then up to 128KB will be stored as "standard" memory data, the additional RAM stored in MEM2-MEM8 blocks.

3. If the snapshot is compressed, then the "standard" memory data will have 0 size and there will be a MEM0 in addition to the additional memory blocks.

4. Version 3 doesn't require memory to be continuous. A Dk'tronics silicon disk on it's own can be described with this version.

5. WinAPE allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.

6. ACE can save additional memory in snapshots (up to 4MB) using the MX?? chunks.

== MX09-40 Chunk (ACE) ==

MX?? chunks allow snapshots to store up to 4160KB ram.

MX?? chunks are following MEM0-8 chunks. They are numbered from 09 to 40 (hexadecimal numbering).
Information are stored compressed like in MEM0-8 chunks.

== BRKC Chunk (ACE) ==

This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.
The number of stored breakpoints in the chunk is given by the chunk size divided by 216 (the size on one breakpoint data structure).

===Notes===

1. The condition is expressed using ACE syntax (similar to BASIC with AND/OR/XOR/NOT/+/-/=...).
Allowed additional syntaxes are:
*&, # or 0x for a hexadecimal number.
*% or &x for a binary number.
*AF, BC, HL, IX... for a 16-bit Z80 register.
*A, B, D, IXh, IXl... for an 8-bit Z80 register.
*FlagC, FlagNC, FlagM... for a Z80 flag.
*LineCount for the line number.
*LineCycle for the µs count on the current line.
*MemPage for the 64K expansion memory page (0-63).
*MemBankMode for the 16K expansion memory bank paging mode (0-7).
*UpperROMOn for the paging state of the upper ROM.
*UpperROMNum for the selected upper ROM number.
*LowerROMOn for the paging state of the lower ROM.
*LowerROMNum for the selected lower ROM number.
*ASICPageOn for the paging state of the I/O ASIC registers page.

''Example : FlagC AND (HL=DE OR HL=&5000)''

2. The map type determines the memory layout for which the breakpoint is valid.
The meaning of the values for map bank and map page depends on the map type value.
Possible values fir map type are:
* 0: Undefined. Map bank and page are ignored (always 0).
* 1: Main RAM. If map bank is 0, then linear main RAM is considered. If map bank is 1, then main RAM from &c000-&ffff mapped as &4000-&7fff is considered. Map page is ignored (always 0).
* 2: Extension RAM. Map bank is the 16K extension bank number (0-3). Map page is the 64K extension page number (0-31).
* 3: Extension ROM. Map bank is the ROM slot id (0-255). Map page is ignored (always 0).
* 4: Firmware ROM. Map bank and page are ignored (always 0).
* 5: Cartridge ROM. Map bank is the 16K ROM bank number (0-31). Map page is ignored (always 0).
* 6: ASIC I/O Page. Map bank and page are ignored (always 0).

== SYMB Chunk (ACE) ==

This chunk is written by ACE when some symbols are declared. When loading a snapshot, the symbols found in this chunk are added to the alreading existing ones.

{|

===Notes===

1. Symbol are (obviously) limited to 255 characters, cannot begin with a number (0-9), and only a limited set of ASCII char is allowed (a-z, A-Z, 0-9, _).

== CPC+ Chunk ==

This chunk is supported by Arnold, Winape, No$CPC and ACE. Arnold, Winape and ACE will save the block when Plus configuration enabled. No$CPC will save the block if the Plus features have been unlocked.

=== Notes ===

1. The sprite data is packed, with two sprite pixels per byte. Bits 7..4 define the first pixel and bits 3..0 define the second pixel.

2. The attributes for each sprite take 8 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| Sprite X (see note)
|-
| 2
| 2
| Sprite Y (see note)
|-
| 4
| 1
| Sprite Magnification (see note)
|-
| 5-7
| 3
| unused (0)
|}

Note: the Sprite X, Y and magnification are in the same order as the ASIC registers

3. This is a direct copy of the palette in CPC+ ASIC Ram. There are 32 colours each with 2-bytes per colour.

4. These bytes in the snapshot represent the last value written to these ASIC registers.

5. These bytes represent the inputs to the analogue channels.

6. The attributes for each DMA channel take 4 bytes. Each attribute block has the following format:

{|
|-
| ''Offset (Hex)''
| ''Length''
| ''Description''
|-
| 0
| 2
| DMA Channel address (see note)
|-
| 2
| 1
| DMA Channel prescalar (see note)
|-
| 3
| 1
| unused (0)
|}

Note: the DMA address and prescalar are in the same order as the ASIC registers.

7 These registers are internal to the CPC+ and define the current DMA operation:

|-
| 0

| 2
| loop address (note b)
|-
| 4
| 2
| pause count (note c)
|-
| 6
| 1
| pause prescalar count (note d)
|}

a. This value represents the number of loops remaining. 0 = none. This count is between 0..0FFF. This counter counts down.

b. This is the Amstrad memory address to loop back to. It is a pointer to the DMA instruction after the last REPEAT instruction.

c. This value represents the pause count and the count is between 0...0FFF. (TO BE CHECKED: down counter? what exactly does it represent)

d. This value represents the pause prescalar count and the count is between 0..FF. (TO BE CHECKED: down counter? what exactly does it represent)

8. This value represents the last value written to this I/O port. Winape uses 8a and not 8b. This value has bits 7,6,5 set to 1,0 and 1 respectively. 8b is in the original specification and is written by both ACE and No$CPC.

9. This value represents the lock status of RMR2. If locked, RMR2 can't be accessed otherwise it can.

10. This value represents the current unlock sequence state.

== WABP Chunk (Winape) ==

This chunk is written by Winape when some breakpoints are set.
The exact details are begin worked out.

It seems to be:

4 bytes - number of user breakpoints

Each user breakpoint:

type,
4 byte address

Then, 4 bytes - number of memory breakpoints

Each memory breakpoint:

Then, 4 bytes - number of i/o breakpoints:

Each i/o breakpoint:

2 bytes flags? (6000 read, a400 write)
2 bytes port addr mask
2 bytes port addr
4 bytes counter
4 bytes condition string length, followed by condition string (not null terminated)

== DARS Chunk (Winape) ==

This chunk is written by Winape when some data areas are set.

The number of stored data areas in the chunk is given by the chunk size divided by 10 (the size of one data area data structure).

ACE (Emulator)

2023-09-21T17:51:41Z

OffseT: Removed duplicated entries

[[File:ACE.png|thumb|German GUI - Main window]]'''ACE''' is a high quality [[Amstrad]] CPC/CPC+ emulator written by Philippe "[[OffseT|OffseT]]" Rimauro.

It is developed exclusively for [http://www.morphos.de/ MorphOS].<br />[[PulkoMandy]] is maintaining the port for [https://www.haiku-os.org/ Haiku].

ACE was coded from scratch, using a real CPC as a reference in order to provide one of the best Amstrad CPC emulator ever.<br />
Most of the games and demos for both CPC and CPC+ are working perfectly; the quality of the emulation is often superior to what the existing CPC emulators on PC/Windows can produce.

In addition to the high quality emulation, ACE features full screen and overlay display (including 50Hz display), editor and analyzer windows for all emulated CPU and chipsets, advanced breakpoints management, a very powerful set of AREXX commands for cross-development, a plugin interface, and much more...

Moreover, ACE is fully translated in French, Spanish, German and English and is still under active development.

== Emulator capabilities ==

ACE emulates most CPC hardwares and their variants.

=== System ===
* Handling of the entire CPC and CPC+ range.
* Full Z80 emulation.
* Up to 256 expansion ROMs.
* Up to 4 MiB of extended memory.

=== Video ===
* Accurate CRTC emulation of the various CRTC types.
* Gate Array full emulation of all variants (perfect split rasters management).
* CPC+ ASIC full emulation (unique quarter-cycle precision).
* CTM644, GT65 and MM12 monitors emulation (including dynamic analog behaviors).

=== Audio ===
* Full and very accurate PSG emulation (AY-3-8912).
* Extremely accurate audio DMA emulation on CPC+.

=== Devices ===
* Accurate but incomplete FDC emulation (Format and Scan instructions are missing).
* Accurate emulation of both floppy disc drives (real rotation speed computation, manual drive & side switches support).
* CPC+ Cartridge port emulation (including upcoming extended cartridges).

Albireo

2023-08-19T08:16:52Z

OffseT: /* Software supporting the Albireo */

== General ==

=== Intro ===

Albireo is an expansion for the Amstrad CPC computers (all models). Its main goal is to provide reliable, fast, cheap and large storage, which it achieves by using a MicroSD card. But the board has a lot of features packed in:
* USB host port, allowing to connect USB mass storage, mouse, and other USB peripherals
* USB device port, allowing to link the CPC to a modern computer with maximal link speed (faster than the z80 can handle, and with on-board buffer and hardware flow control).

The interface is based on the WCH CH376 chip and allows access to USB mass storage and other USB devices on CPC.

The CH376 chip implements FAT32 in hardware, which means no filesystem driver is needed on the CPC side. It also implements the lower level aspects of USB, making it relatively easy to write drivers for other USB devices (mouse, joystick, ...).

=== What's in it? ===
* SD and SDHC card mass storage support with fast (6 MHz) SPI link with the SD card. Hardware FAT32 support for easy file access. Raw sector access also possible for homegrown file-systems and other advanced applications.
* USB host support with built in mass storage driver, also with FAT32 and direct sector access.
* Generic USB host with direct control of USB endpoints, for connecting other kinds of USB devices.
* High-speed (1.5 Mbaud) serial link with built-in USB interface for linking with other computers for fast data exchange. Includes flow control, 16 byte FIFO on CPC side, and 512 byte FIFO on remote side, allowing fast buffered and interrupt-driven operation.
* Software configurable interrupt routing to either NMI or INT, or interrupt masking. Multiplexing of several interrupt sources: USB host controller, UART, remotely triggered, and CRTC CURSOR signal interrupts are gathered and easily accessible from a single interrupt status register.

=== Board revisions ===

The hardware went through multiple iterations before reaching final state. Each version identifies itself on the USB link and the version should be visible in Windows device manager or lsusb on Linux.

==== Initial prototypes ====

The first prototype was an hand-wired one. There were some changes to I/O ports used since then, so it is not usable anymore.

==== Version 0.9 ====

The first 5 boards were manufactured with an early PCB design, which required some wire-patches to get things working. With the wire-patches, this version behaves the same as 1.0.

==== Version 1.0 ====

About 20 boards were shipped with version 1.0. Unfortunately, as people started to write software using it it turned out that the serial port chip has compatibility problems with the z80 timings. As a result, this version of the board can use the serial port only with the FIFO disabled, which makes it impossible to reach high baudrates. The board is still perfectly usable if you are interested only in the microSD and USB host port.

==== Version 1.1 ====

This version of the board replaces the serial chip with a slightly different one. The board still reads "v1.0" as it is the same PCB, only the chip used has changed.

You can identify your board from the info it sends on the USB device port, or by checking the serial chip (square chip on the back of the board).
Version 1.0 uses a TI TL16C550D chip. Version 1.1 uses a NXP SC16C650B chip.

=== How does it work? ===
* There are two main devices: the CH376 handles the USB host and SD card side of things, and is accessed at FE80 (data) and FE81 (command/status). The communication side is handled by a SC16C650B, mapped at FEB0-FEB7. This is similar to the chip used on most PC hardware and some Amiga expansions like the SilverSurfer.
* There is an FT230X chip to convert the UART to USB for connecting with a modern PC (standard serial ports are not that common anymore, and they wouldn't be fast enough anyway). The FT230X also generates 12MHz and 48MHz clocks for the two other chips.
* The 16C650 "modem control" lines are connected to various things (CH376 interrupt, FT230X general IO pin for remote control) and turns them into interrupts.

=== What is it useful for? ===
Not much currently because there is no software yet, but in the future:

* Use the USB key or SD card directly from BASIC and well-behaving apps (which support extra disk ROMs and a C drive). Load games and tools from the mass storage media
* Connect to another computer like the CPC Booster, load snapshot, DSK or other files from it and write them to floppies or the mass storage media. A snapshot of 128K could be loaded in 0.86 seconds, a snapshot of 64K in less than 0.43 seconds.
* Use SLIP (serial line IP) and a properly setup gateway (Linux machine or similar) to connect the CPC to the Internet.

There are a drivers in FutureOS and SymbOS to use Albireo with an USB mouse.

== Hardware ==

=== I/O ports ===

The decoding is clean, this means there aren't any mirror ports or undecoded address bits. Just the addresses listed below are used.

The addresses are in the I/O range, which means you access them with the OUT and IN instructions. They are not memory mapped, and to match with the CPC address decoding, the address is decoded on 16 bytes. This makes using OTIR and similar looped instructions tricky, but is required for compatibility with the CPC.

==== CH376 registers ====

* FE80: "DATA" port (read/write)
* FE81: "COMMAND" (write) and "STATUS" (read) port

==== SC16C650B registers ====

Some of the registers are sharing the same address. A register bit (DLAB) is used to switch between the two groups.
<tt>
{|
|-
! Address !! DLAB !! Description
|-
| FEB0 || 0 || RBR/THR: RX buffer (read), TX buffer (write)
|-
| FEB1 || 0|| IER: Interrupt enable
|-
| FEB0 || 1|| DLL: Divisor latch LSB
|-
| FEB1 || 1|| DLM: Divisor latch MSB
|-
| FEB2 || || IIR/FCR: Interrupt status (read), FIFO control (write)
|-
| FEB3 || || LCR: Line control
|-
| FEB4 || || MCR: Modem control
|-
| FEB5 || || LSR: Line status
|-
| FEB6 || || MSR: Modem status
|-
| FEB7 || || SCR: Scratch register
|}</tt>

=== DIP switches ===
The board holds 4 DIP switches for configuration. From top to bottom:

==== S1 - CH376 interrupt enable ====

* When this switch is ON, the usb controller is allowed to generate interrupts to signal the CPC when it is done performing an operation.
* When this switch is OFF, the usb controller is not allowed to generate interrupts. The CPC must then poll the CH376 STATUS register to know wether the operation is finished.

==== S2 - CH376 reset enable====

* When this switch is ON, the CH376 will be reset at the same time as the CPC (hardware reset only).
* When this switch is OFF, the CH376 will not be reset, and the CPC must initialize it using the reset command (software reset). In this case, the CH376 internal buffer may be used to store reset resident data (but I don't know if this is of any practical use, yet).

==== S3 - Remote reset enable ====

* When this switch is ON, the DTR signal from the remote side of the serial link is connected to the CPC reset. This means that the remote side computer can trigger the CPC reset by toggling that line.
* When the switch is OFF, such reset is not allowed and the CPC is safe.

==== S4 - Remote interrupt enable ====

* When this switch is ON, the DTR signal from the remote side of the serial link is plugged to the DSR line of the UART controller. It then generates an interrupt which the CPC can process.

X-MASS

2022-09-29T20:53:37Z

OffseT:

The X-MASS is an ATA/IDE interface for the CPC made by [[TotO]] of [[ACME]]. Released on December 25th 2014.

The interface comes with a 128MB or 512MB 44-pin Disk-On-Module device. This is connected as master and by default the X-MASS only supports a single device.

It is possible to remove this and use with other compatible ATA devices with an adaptor provided they support 8-bit data transfer. (e.g. CompactFlash).

== Technical ==

The device uses the same IDE I/O ports (except for the alternative status register and drive address register) than the [[SYMBiFACE II]] and is therefore compatible with it.

The port range it supports is FD08-FD0F.

When the X-MASS is powered on the CPC is held in reset while the X-MASS communicates with the Disk-On-Module. If all is good the reset is released and the CPC starts up.

During this reset time the X-MASS sets the device into 8-bit PIO mode using SET FEATURES ATA command. The X-MASS device therefore requires "newer" IDE devices which support the CFA ATA mode because the 8-bit PIO is part of that command set.

It is possible to use SET FEATURES to put the X-MASS into 16-bit mode, but then you would only read 8 of the 16-bits of data that ATA devices often use, and you would only be able to use half the capacity of the device and you would not be able to read devices formatted on the PC for example.

In default configuration the X-MASS operates the same as the SYMBiFACE II IDE and has the same functionality.

The I/O ports operate in a "pass-through" like mode where the registers directly reflect those of the connected ATA device.

Like the SYMBiFACE II, the device should be selected with port FD0E first, then the other I/O ports can be used to program the selected device.

The I/O port is decoded fully:

1111 1101 0000 1xxx (xxx for registers 8-f)

OffseT: /* Additional */

[[File:ACE.png|thumb|German GUI - Main window]]'''ACE''' is a high quality [[Amstrad]] CPC/CPC+ emulator written by Philippe "[[OffseT|OffseT]]" Rimauro.

It is developed exclusively for [http://www.morphos.de/ MorphOS].<br />[[PulkoMandy]] is maintaining the port for [https://www.haiku-os.org/ Haiku].

ACE was coded from scratch, using a real CPC as a reference in order to provide one of the best Amstrad CPC emulator ever.<br />
Most of the games and demos for both CPC and CPC+ are working perfectly; the quality of the emulation is often superior to what the existing CPC emulators on PC/Windows can produce.

In addition to the high quality emulation, ACE features full screen and overlay display (including 50Hz display), editor and analyzer windows for all emulated CPU and chipsets, advanced breakpoints management, a very powerful set of AREXX commands for cross-development, a plugin interface, and much more...

Moreover, ACE is fully translated in French, Spanish, German and English and is still under active development.

== Emulator capabilities ==

ACE emulates most CPC hardwares and their variants.

=== System ===
* Handling of the entire CPC and CPC+ range.
* Full Z80 emulation.
* Up to 256 expansion ROMs.
* Up to 4 MiB of extended memory.

=== Video ===
* Accurate CRTC emulation of the various CRTC types.
* Gate Array full emulation of all variants (perfect split rasters management).
* CPC+ ASIC full emulation (unique quarter-cycle precision).
* CTM644, GT65 and MM12 monitors emulation (including dynamic analog behaviors).

=== Audio ===
* Full and very accurate PSG emulation (AY-3-8912).
* Extremely accurate audio DMA emulation on CPC+.

=== Devices ===
* Accurate but incomplete FDC emulation (Format and Scan instructions are missing).
* Accurate emulation of both floppy disc drives (real rotation speed computation, manual drive & side switches support).
* CPC+ Cartridge port emulation (including upcoming extended cartridges).
* Emulation of the tape interface through audio files (read only).
* Accurate emulation of the keyboard (including ghost keys when pressing more than three keys at once).
* Automatic keyboard remapping can be activated if your are using ACE with a keyboard layout unknown by the original CPC firmwares.
* Plugins interface to support virtually any external device.

== Graphical interface ==

ACE MUI graphical interface is designed to be versatile and very easy to use, and everything is always updated in real time to match the actual emulator state.

* Simple and modular configuration of the CPC profiles to emulate using tool types (from Ambient) or arguments (from CLI).
* Ability to change the CRTC type or the screen monitor model on-the-fly without having to reset the running program.
* SNA and DSK files management (all of them!) with automatic on-the-fly detection and fix of the corrupted DSK.
* CPR files management for CPC+ cartridges (including support of extended cartridges up to several hundreds on megabytes).
* Overlay support with real pixel aspect ratio.
* Full screen support with the ability to choose the graphic mode to use in order to get back the 50Hz smoothness if your screen monitor can do this.
* Maskable interface in both windowed & full screen modes.
* Floppy disc drives LED activity OSD when the interface is not displayed.
* Rich breakpoints management on predefined conditions (HBL, VBL, interrupt...), on graphical coordinates, on execution addresses, on memory accesses and on I/O ports accesses (with the ability to use complex conditions, masks on the break address and/or the break value) with the option to execute scripts.
* Video beam cursor to see the cathode's ray position while on pause or in step by step mode.
* Memory editor (management of all RAM and ROM switching, automatic detection of the character code page depending on the installed firmware ROM).
* Z80 disassembler with highlight on opcodes and fast jump buttons on branch instructions.
* CRTC editor (full real time read/write access to the registers).
* Z80 editor (full real time read/write access to the registers).
* Gate Array analyzer (palette display, graphic mode, interrupt internal counter).
* PSG analyzer (played notes, tuning, and a bunch of rich information from the current PSG settings).
* Hard sprites analyzer (palette and content).
* DMA analyzer (full real time state and instructions being executed).
* Video information window (frequencies, beam ray position...).
* Virtual keyboard and joysticks.
* Ability to map joystick to keyboard when in case real joystick is available.
* Internal keyboard matrix state observer.
* Screen monitor settings window (type, brightness, vertical hold).
* Sound volume control.
* Online help and MUI's bubbles help available everywhere to help the beginners.

== Programmable interface ==

ACE is designed to be expandable and controllable. You are not limited to the core emulation and can you easily integrate it in any cross-development tool chain.

=== Plugins ===

ACE support plugins that allow anybody with some C language knowledges to add support for expansions connected to joystick, printer or expansion CPC port.

==== Default ====
* Both [[joystick]]s (up to three fire buttons) using real devices plugged on the host machine (using USB or whatever).
* [[Printer]] (redirected to a file).
* [[Multiface_II|Multiface Two]] (well known hardware debugger and snapshot handler).
* [[Digiblaster|Digiblaster/Soundplayer]] (8-bit mono sound card).
* [[Kempston Mouse]].
* [[AMX Mouse]].
* [[Gunstick]] (light gun).
* [[Amstrad Magnum Phaser]] (light gun).
* [[Trojan Light Phazer]] (light gun).
* [[West Phaser]] (light gun).

==== Additional ====
* [[Albireo]] (MicroSD, USB, and more).
* [[X-Mass]] (IDE interface).
* [[Dandanator]] (programmable game cartridge module)
* [[Nova]] (NV-RAM and RTC).
* [[MultiPlay]] (additional mice and joysticks ports).
* [[Willy]] (up to 18 channels FM synthetizer sound card).
* [[PlayCity]] (6 voices PSG sound card).
* [[Amdrum]] (8-bit mono sound card).
* [[Amstrad_SSA-1_Speech_Synthesizer|SSA-1]] (english speaking speech synthesizer).
* [[Dk%27tronics_Speech_Synthesizer|DK'Tronics Speech]] (english speaking speech synthesizer).
* [[TMPI speech synthesizer|Techni-Musique Speech]] (multilingual speaking speech synthesizer).
* [[Mirage Imager]] (hardware freeze and snapshot handling).
* Cycle counter (developer helper).
* [[Programming:Cartridges#Dandanator|Dandanator]] (ROM mapper).

=== Scripting ===

Any scripting language (such as Python, Lua or of course AREXX) can be used to control ACE through its AREXX interface. It gives you full control on the emulator in order to automate things (and much more), or even to use ACE as a powerful cross-development station (including integration into an IDE).

Peripheral Soft Reset

2022-09-10T08:26:40Z

OffseT:

Port F8FFh is a documented, but rarely known I/O address, used by the standard BIOS functions MC_BOOT_PROGRAM and MC_START_PROGRAM (vector BD13h and BD16h). These functions are usually executed when starting a binary program with RUN"FILENAME.BIN", both functions do issue an "OUT [F8FFh],FFh". This feature is intended to allow Peripherals to re-initialize themselves when needed. From the official [[SOFT158]] specs:

:"All expansion peripherals should be reset when an output is performed to I/O channel #F8FF. In particular a peripheral that generates interrupts must not generate an interrupt until it is re-initialised after such an output has been performed."

Most or all peripherals (including Amstrad's own [[DDI-1]]) aren't following that suggestion, and usually there is no need to do so. There may be a few special cases there hardware could take use of it, such like interrupt generating devices, especially if they do access formerly allocated memory.

== Avoid this ==

* Software should never write to (or even read from) Port F8FFh. That might cause connected Peripherals to reset themselves.

* Hardware should not perform any actions (other than the intended Soft Reset action) upon accessing Port F8FFh. Eg. producing hardware that formats the disc on write to Port F8FFh would be no good. This applies also on incompletely decoded addresses, eg. formatting on write to Port F8F0h, but also mirroring that action to F8FFh.

* When intentionally using the feature, be sure to have the port fully decoded. Ie. do not re-initialize your hardware on writes to other 'nearby' ports like F8EFh ([[Schneider RS232 Interface]]).

== Known Hardware ==

The Soft Reset feature is useful (initialize hardware expansions), but no used a lot; the [[PlayCity]], [[Nova]] and [[CPCISA]] are the only hardware expansion using intentionally this feature (though when reverse engineering things by only examining the software drivers one may easily miss its presence, since the OUT [F8FFh] is issued by the BIOS, not by the driver).

Moreover, there are probably various devices that do not directly use Port F8FFh, but that do react to the OUT because of incomplete port decoding. For example, the [[ACU Real Time Clock (DIY)]] decodes only A10,A4,A3 of its Port FBFFh, and so, it will also react to OUT [F8FFh],FFh.

OffseT:

[[Yarek]] aka '''Jarek Adamski'''.

== Hardware ==

* [[CPC4MB]] - 4MB RAM expansion
* [[CPC.Flash]] - 4MB ROM expansion
* [[CPCISA]] - ISA bus (for using PC ISA cards) (originally developed by [[Siou]])
* [[IDE8255]] - Harddisk Interface

Note: There is also something called [[YaPaDOS]], which seems to be [[Yarek]]'s (?) Patched Parados/Amsdos ROM for supporting his [[IDE8255]] (?) harddisk interface?

I/O Port Summary

2022-09-10T08:23:33Z

OffseT:

This is a list of all known I/O ports of the Amstrad CPC, including all [[Peripherals]]. For a list showing only the built-in standard addresses see [[Default I/O Port Summary]]. The original list of I/O ports was taken from the [[FutureOS]] handbook.

== I/O Port Summary ==
Note: While most of these devices can be reached via a range of addresses due to the partial address decoding, code should never use any address other than the canonical one (all 'x'/don't care positions filled by 1's). Otherwise multiple devices will be enabled simultaneously, which is unlikely to be what you want.

== More Ports ==

Some more I/O addresses (which aren't included in the above list yet) are here:
* [[Schneiderware Summary]]

== Other I/O Ports ==

A number of peripherals connect to the joystick/printer ports, and so, they do not include "own" I/O addresses. This includes hardware ''other than joysticks/printers'' - for example, mice, robots, audio devices, and simple network adapters. For a more complete list, see corresponding sections on [[Digital Joysticks|Digital Joystick]] and [[Printer Port]] pages.

Aside from I/O addresses, there are some other important I/O signals, for example: [[NMI]] or [[External Interrupt|INT]].

CPCISA

OffseT: Created page with "Category:Peripherals Prototype of the CPCISA card === What it is === CPCISA is a project created by Siou, also hosted/worked on at..."

[[Category:Peripherals]]
[[Image:Cpcisa2b.jpg|200px|thumb|Prototype of the CPCISA card]]

=== What it is ===

CPCISA is a project created by [[Siou]], also hosted/worked on at [[Yarek]].

Basically, it is a hardware add-on that lets you connect ISA cards to your old CPC! Some examples of what it can offer:
*An I/O interface (Serial and parallel ports, Floppy and IDE ports)
*An internal (card) modem (probably a full-featured modem is needed; that is, not a winmodem/softmodem)
*A SoundBlaster card (or 100% compatible)
*A network card

ISA cards were almost fully supported, including 16-bit mode and vectorized interrupts(thru Z80 IM2). Only video cards were not supported (CPCISA decodes only I/O ports, not memory mapped VRAM).

=== Status ===

The card is working, however only five of them were built (including the initial dev board). This is because the card was complex and outdated, ISA peripherals and the AT standard became old and difficult to find.

Most CPCISA softwares were created by Siou himself (IDE hard disk, ethernet and mouse drivers, as well a an audio sample player thru SoundBlaster 8-bit interface). Initial OS support was done by [[Futur's]] with a set of two ROMs ("Interrupt Lib" ROM to add vectorized interrupt support to Locomotive Firmware, and "ISA ROM" with low level ISA routines). [[Madram]] also created an Adlib music player supporting SA2 module files, which was later adapted by [[PulkoMandy]] to play these modules with the [[Willy]] card equipped with a OPL3LPT device.

It was mostly a proof of concept; none of the drivers and software came to a state really usable for the end user (no filesystem support, no TCP/IP stack...).

Peripheral Soft Reset

2022-09-06T15:43:05Z

OffseT: /* Known Hardware */

Port F8FFh is a documented, but rarely known I/O address, used by the standard BIOS functions MC_BOOT_PROGRAM and MC_START_PROGRAM (vector BD13h and BD16h). These functions are usually executed when starting a binary program with RUN"FILENAME.BIN", both functions do issue an "OUT [F8FFh],FFh". This feature is intended to allow Peripherals to re-initialize themselves when needed. From the official [[SOFT158]] specs:

:"All expansion peripherals should be reset when an output is performed to I/O channel #F8FF. In particular a peripheral that generates interrupts must not generate an interrupt until it is re-initialised after such an output has been performed."

Most or all peripherals (including Amstrad's own [[DDI-1]]) aren't following that suggestion, and usually there is no need to do so. There may be a few special cases there hardware could take use of it, such like interrupt generating devices, especially if they do access formerly allocated memory.

== Avoid this ==

* Software should never write to (or even read from) Port F8FFh. That might cause connected Peripherals to reset themselves.

* Hardware should not perform any actions (other than the intended Soft Reset action) upon accessing Port F8FFh. Eg. producing hardware that formats the disc on write to Port F8FFh would be no good. This applies also on incompletely decoded addresses, eg. formatting on write to Port F8F0h, but also mirroring that action to F8FFh.

* When intentionally using the feature, be sure to have the port fully decoded. Ie. do not re-initialize your hardware on writes to other 'nearby' ports like F8EFh ([[Schneider RS232 Interface]]).

== Known Hardware ==

The Soft Reset feature is useful (initialize hardware expansions), but no used a lot; the [[PlayCity]], [[Nova]] and [[CPCISA by Yarek|CPCISA]] are the only hardware expansion using intentionally this feature (though when reverse engineering things by only examining the software drivers one may easily miss its presence, since the OUT [F8FFh] is issued by the BIOS, not by the driver).

Moreover, there are probably various devices that do not directly use Port F8FFh, but that do react to the OUT because of incomplete port decoding. For example, the [[ACU Real Time Clock (DIY)]] decodes only A10,A4,A3 of its Port FBFFh, and so, it will also react to OUT [F8FFh],FFh.

Moreover, there are probably various devices that do not directly use Port F8FFh, but that do react to the OUT because of incomplete port decoding. For example, the [[ACU Real Time Clock (DIY)]] decodes only A10,A4,A3 of its Port FBFFh, and so, it will also react to OUT [F8FFh],FFh.

I/O Port Summary

2022-09-06T11:44:39Z

OffseT: /* I/O Port Summary */

This is a list of all known I/O ports of the Amstrad CPC, including all [[Peripherals]]. For a list showing only the built-in standard addresses see [[Default I/O Port Summary]]. The original list of I/O ports was taken from the [[FutureOS]] handbook.

== I/O Port Summary ==
Note: While most of these devices can be reached via a range of addresses due to the partial address decoding, code should never use any address other than the canonical one (all 'x'/don't care positions filled by 1's). Otherwise multiple devices will be enabled simultaneously, which is unlikely to be what you want.

== More Ports ==

Some more I/O addresses (which aren't included in the above list yet) are here:
* [[Schneiderware Summary]]

== Other I/O Ports ==

A number of peripherals connect to the joystick/printer ports, and so, they do not include "own" I/O addresses. This includes hardware ''other than joysticks/printers'' - for example, mice, robots, audio devices, and simple network adapters. For a more complete list, see corresponding sections on [[Digital Joysticks|Digital Joystick]] and [[Printer Port]] pages.

Aside from I/O addresses, there are some other important I/O signals, for example: [[NMI]] or [[External Interrupt|INT]].
