Just an FYI - I was able to get the apple II gs emulator, Bernie ][ the Rescue, running in sheepshaver on my vista machine. Thus, an emulator within an emulator.
Was able to play Arkanoid II and California Games (and I assume all others as well), which brought back some great memories.
Just followed the guide here. http://www.whatisthe2gs.apple2.org.za/
