The latest cartridge PCB revision has fixed the instability issues, as I had hoped, and I now have EEPROM support working as well! So this is now basically a full cartridge emulation solution for the Atari Jaguar. It all needs a tidy up, but functionally it’s complete. Next I need to look at the CD emulation and make sure that’s all possible with the current PCB revision. The actual CD support can come after initial release if needed, but I need to make sure it can be done!
