Really? I always thought the key was just a list of offsets to help the emulator figure out which precise ROM dump it's using. Hmm... This might also be something to check on, indeed. Though, the latest Amiga Forever is supposed to run on Mac, too... I wouldn't think they'd do anything TOO proprietary!
Nah, the ROM with AF are protected.. Cloanto payd to distribute Amiga ROMs, so I guess they wanted to protect them.. Not really sure tho about this, AFAIK, the ROMs need to be a certain size, otherwise the checksum should fail ?
Anyway, UAE set the standard for Amiga ROM and disk images, so if a rom works on WinUAE, then it works on MacUAE or LinUAE as well..
