In my quest for completionism of some of my favorite game series, (Castlevania, Mario, and Star Wars) I downloaded the M88 and winx68k emulators, and, being a mac user, converted them to mac applications using Wine. Now, I have run into problems with using these. winx68k demands a bios file that i have no idea what it is, and M88 seems to work, but then shows only a white screen when i open a game. I got the title theme from Punchball Mario Bros. to play, but it didn’t show anything else. Is there anyone out there that could provide some guidance with these?
