File:Wolfenstein 3D on the Apple IIGS

Me playing Wolfenstein 3D on a real Apple IIGS running at 10mhz with the help of a ZIPGSX card. Even at that speed, the game runs pretty slow in full screen mode. Luckily you can adjust the screen size to increase performance. You need at least 12.5mhz and 64k cache I'd guess to run it properly on a IIGS.
