	The complete hardware of the MegaROM was developed by [[User:Bryce\|Bryce]] of [[FutureSoft]]. The original idea came from discussions with [[TFM]] of [[FutureSoft]]. The main goals being that it would offer up to 16 ROM positions, be very low cost and be a single-sided PCB design so that it could be easily built by most electronic hobbyists.

	Using your favourite EPROM Programmer, you can burn the ROM images to the locations shown below. You can either do this ROM for ROM or compile one single ROM file to burn in one go. You should set the EPROM programmer to only write to the area required, in case you want to add additional ROMs later, any unwritten area will be regarded as empty by the CPC. Below you can see the memory allocation for each virtual ROM within the EPROM. This file is also available below in PDF Format.

However, adding two or more ROMBoards to a CPC in Parallel will cause crashes in some circumstances.
