Looking for help with understanding the MC68000 instruction set. Or better yet, ROM hacking arcade games running on the 68k.
Context: I want to do a ROM hack for Dodonpachi. There was an extremely rare version that goes by "campaign version" or "blue label". Between CAVE saying they've lost the source code and the few people owning the PCB not dumping the ROM yet, it seems unlikely we'll ever get access to the official version. So I thought, "Fine, I'll do it myself."
Of course, I don't expect to be able to recreate it 100% accurately. Close enough is my goal.
