First off, unless there's a newer version I'm unaware of, Ray's Wofenstein AtariST port is pretty limited. It is a recompile of the AppleIIgs game. You can't shoot back, can't do anything more than run around the first level. What is more, you need a 4MB ST to make it run, iirc. No doubt it can be improved upon. Heck, didn't Citadel show that a Wolfie clone would work on a stock A500?
