How's your Dr PC Jr projects going? U know there are alot of us users out there that would love to be able to play and save SRAM games (like Crystalis, which I got working flawlessly).
Is it possible to be able to use NES carts as dummy carts for unsupported mappers? Kinda like how u need a DSP game cart plugged into a SNES copier to play DSP chip games.
Let us know how your progress is.
P.S. the PC Jr's controllers suck...how about using NES controlls on it?
