I'll try to be more clear. the Genesis game had a battery in it that the SNES game did not. no emulator is likely to correctly mimic that feature, regardless of what computer you use. when it comes time to load saved data that would be found on the batteried chip, the data isn't there. it won't work. now, later, PC, Mac, emulator1, emulator2. try SNES, it's password-based, instead.
