I tried Vice on WinUAE just to see what it would do. A PC emulating a Amiga emulating a C64 was just an interesting if pointless experiment.
You're right about Spectrum emulation on AMiga being superb (although FUSE is bad.). I keep meaning to test other emulators on the Amiga. I'll get round to it eventually.

BBC Micro and PC XT emulation were both pretty good. Atari ST emulation sort of worked, but I never managed to get any games to work, just GEM.

That was my intention, to test if it would work, but unfortunately it's very slow.

Faster than a normal Amiga though.
