Emulators on OS 9

Mac OS 9 isn't just a great operating system - it also offers the possibilty to emulate a lot of other systems, from 80's home computer classics like the Commodore 64 to Windows XP machines. And don't forget game consoles like the (S)NES, Genesis / Mega Drive and others too! We're looking for somebody who would be willing to help us reviewing the available emulators on Mac OS 9. If you can help us out with that, please let us know!
