Moerder: I looked into the F8 system today (CPU, PSU etc.). What the hell kind of madman came up with that design? I see your point in it being a pain.
A custom cartridge would either have to use one of those existing address decoders + EEPROM. That or just roll one's own with a microcontroller (which could act as ROM and RAM)..

Yes, isn't it just wonderful?

I mean, mostly because of the CPU this system is so sick, if I had one I'd simply HAVE to do some development for it :D
