QEMU doesn't emulate 680x0 processors, but Basilisk II does, and with MMU emulation, Basilisk II could run A/UX. Speaking of MMU's, Basilisk II could really use MMU emulation. Does QEMU work with Mac OS 7 or 8? I'll have to test when I get home later today. However, the big advantage QEMU has is memory management unit emulation, thus allowing you to run Mac OS 9.1 and later SheepShaver has no MMU emulation and as such can only run up to Mac OS 9.0.4. It also supports Mac OS X Leopard, something PearPC doesn't (remember, PearPC hasn't been updated since around 2011, IIRC).Īs for Mac OS 9, it seems to be around the same as SheepShaver. Funny, I was researching about this just yesterday! From what I've read (haven't tested anything yet so don't take my word for it), QEMU runs PowerPC versions of Mac OS X much better than PearPC does.
