I was not sure where to post this. I don't see any threads on modifying your own code and making your own ROMs. I goy into this with my car hobby a while back, writing my own code for my 1987 Buick Grand National which used a very similar Motorola 68000 CPU. There were a lot of resources with documented disassembled code.
Are there any resources for code for old first generation SS Ballys? I have an Embryon, and an Eight Ball I thought it would be fun to play with.
