So why would you want to emulate a Mac on a Mac? The answer is simple. Try running all those old classics, like Dark Castle, Beyond Dark Castle, the Fools Errand, and so on, on a Mac without a 9-inch monitor. They don't work. vMac, however, enables them all to work perfectly. The first ever emulator for the Mac - ][ in a Mac - which does nothing useful when run on a G3 - works perfectly in vMac. vMac also supports full sound emulation.
Mac OS 8.6 or later, CarbonLib.
