What's going on exactly on A130EC with 32X? Had a quick look online, games do read there for a keyword (so effectively EC-EF), but mapper is only dealing with writes, not reads.I am missing something there ? :? Also are the standard board holes exact potitions available somewhere? Thoses are quite o...
Yeah it looks like it's possible with the same CPLD chip (100% macrocell & pin usage, I guess it was made for the task heh). It might however not 100% replicate the SEGA mapper as there's not enough pins to catch A4-A7. This means writing 0xA13003 will be the same effect as writing 0xA130F3. Not a h...
Happen to be disgressing a bit from NeoGeo lately and I did prototype such a Gb card for the megadrive. Wasn't aware of the !time signal back then so this test card is designed to switch banks by writing to the ROM region (0x0-0x3fffff). Was able to barely fit 7 selectable windows in CPLD, so it can...

It is fairly simple if you only need genesis > arduino communication (not bidirectionnal) You need two things wired to arduino: - a decoded write signal. A couple basic logic gates will do that for you, setup depends on the signal/memory range you are looking for. - data bus. Obvious reason, wire 8 ...
