At some point in the near future hopefully, QEMU will fully replace SheepShaver, but at the moment, SheepShaver still runs faster in most situations. Note that QEMU can also emulate Mac OS X 10.0 up to 10.5. In 2016, QEMU could finally achieve what has never been possible before: emulating Mac OS 9.0.4, 9.1 and 9.2.2 (albeit still it's quite slow and the sound support is kind of buggy at the moment). QEMU is a very versatile and extremely broadly supported open source virtual machine emulator. What is QEMU for Windows - PPC emulator, runs Mac OS 9.1, 9.2 + OSX 10.0 to 10.5?
