You could probably run a DOS game on a DOSBOX running on a PPC, I just don't see running games on a 68K Amiga (would be too slow I think).
Is anybody going to try it?
I have DOS emulater software for the Mac (works on 68K) and to run Windows 3.1 the manual says you need a PPC machine. I snagged a Nubus 386/25 card for one of my Macs and it runs great except it only emulates CGA video (unless I rip the machine up to install a VGA card onto the Nubus card). So even if a 68K could emulate a DOS game how would you run the VGA graphics? My 286 bridgeboard on my 2000 can only do CGA unless I install a CGA card.
