High Quality Content by WIKIPEDIA articles! Sixtyforce is a shareware Nintendo 64 emulator created exclusively for Mac OS X. It natively supports both x86 and PowerPC-based machines. Sixtyforce doesn't support as wide a range of games as Mupen64Plus (the only other active Nintendo 64 emulator that supports Mac operating systems, aside from the obsolete TrueReality and Mupen64 emulators), but still supports PPC : most games that work run at playable speeds on late-generation G4 and all G5 processors.
