Intel-based Mac owners, however, can play the IIgs games by downloading a standalone emulator linked to from the Virtual Apple ][ site. A standalone Apple II emulator is also available. The site owners said they "will soon be offering a complete download package of all disks. We also are expecting a Mac OS X compatible version of the emulator sometime soon."
Since the games run in a browser, players simply click "Switch disk" to move between virtual floppies, with buttons available to reset the game or restart the virtual computer. Unfortunately, some games work better than others, so your mileage may vary.
