I'm messing around with some protos from drx's big release and am getting curious what else you can find within roms that isn't out in the open in-game. Anybody able to tell me the general process? And no answers like "get a hex editor", that's way too general and I don't know where to start at all by just downloading that and staring at the huge amass of numbers
You could try something like what the guys at SMSpower's GDRI did to find out shared engines in different games. There's a little info on how they did some heuristic searches over here, but I don't know wether they've released their tools or not... and anyway it would be somewhat tiresome to do with all the existant Mega Drive ROMs (although it would be useful for looking for pieces of the most relevant games in the GoodGen romset). Sorry I can't be more helpful. =\
