I wonder why it's faster - specifically *how* it's more efficient. (Admittedly an expansively broad question; summary responses accepted!)

- grishka 5y agoIf my understanding is correct, it doesn't implement the MMU (which latest OS 9 versions require), takes some other shortcuts and does JIT.
- wk_end 5y agoqemu actually tries to emulate all of the hardware in a Mac; also, I believe its CPU emulation is just interpreted though someone correct me if I'm wrong. SheepShaver emulates the CPU with a JIT and then patches the emulated MacOS so that calls to it run as native code.
- anthk 5y agoSheepShaver is hacky, I know it since BasiliskII times, same people. SS is faster, but nowadays the gap against Qemu is not that big on a modern machine. Also, Qemu will provide an ATI Rage device for the G3/G4 machine, so you may be able to correctly play a good chunk of 3D games released for Mac OS 9. >I believe its CPU emulation is just interpreted Something between interpreted and a JIT.
