I cheat and run my old Workbench desktop environment under WinUAE. The Sysinfo benchmark reacts hilariously when it's running on top of a modern CPU (the "your performance" comment reads "Phone me NOW!!!!!", when it finds that you somehow have a system that runs at 94x the speed of an A4000/40). I have many of the games you mention and a few of my old apps (I made the cover disk of Amiga Format - by golly, that made me feel smug for a long time). Although I am embarassed to admit that a clock I wrote in '94 isn't Y2K compliant and reports this year as "120". Darn it.
