/diy/ - Do It Yourself

Not sure where to ask this. I'm interested in making super nintendo repros. Programming something like a 27c801 and replacing the maskrom on an snes cart with it. Pinouts are always different when working with snes carts though.

Some people have made programs that byte swap the rom so you don't have to physically rewire all the pins. Pic related, the binary data for address pins A19 and A17 are flipped. I want to modify the code to support different eeproms than the 27c801.
