Cool! Good work :)
Actually I was halfway into implementing the unlock/lock sequence, when I found that the best solution is to keep the CPC and CPC+ modes seperate. This using a .CPR/.BIN rom image and starting it with |CTR when wanting to use CPC+ mode roms on M4.
Ie. for one compatilibity with C4CPC.

I may change my mind again, but for now that would be the safe distribution form.


You mean, no change ?

I think that is the overall best solution. Use .CPR / .BIN with the correct roms setup. Came to think of it M4 is the only hardware that does have CPC+ ROM mapping and also runs on classic CPC, so there is no best practice (yet). In |CTR mode all cartridge ROMS are disabled via ROMDIS and M4 owns the entire ROM space, in normal mode, they can co-exist but if M4 starts mapping roms according to RMR2 bit, I dont think cartridge games nor C4CPC can co-exist.

 :picard:

1. With your first fixed, i have no problems! IMPdraw v2 runs perfectly and all the demos/games i’ve tested too.
2. With iMPdos i have no problems too.


Unfortunately, I won’t do any cartridge version for the moment...
