* [[Utopia]] should always be in an upper slot than [[UniDOS]]. Utopia in lower slot than UniDOS will disable some UniDOS [[RSX]]. [https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/m4-unidos-and-cpcatx4/msg249541/#msg249541 Source]
* [[ROM List]] listing of known ROM-based software
* You may want to add a list of devices with ROM here, please also include their fixed bank number(s), or selectable range of bank number(s))
And on 6128+ only, physical ROM 3 is mapped to logical ROM 7. The ASIC is configured not to map it on 464+ and GX4000, even if a 6128+ cartridge is inserted.
Logical ROMs can be replaced by using a [[ROM board]] while physical ROMs cannot be replaced.

ROM 0 can always be overloaded, but remember that you will not boot to the BASIC in that case ([[Hackit|the Hacker ROM]] is a popular replacement ROM 0, for example).
