Even not regarding legal issues, they are very different internally and are coded to work with specific hardware set-ups. Lastly, there's dealing with Old World and New World ROMs.

#Powerpc emulator for intel mac drivers

Both Sheepshaver and PearPC use barebones drivers just good enough for displaying images, but not so much acceleration. It's just with firmware coded specifically for the Mac. If it's any consolation, the video cards in most PPC Macs are pretty much the same NVidia and ATI cards seen in PCs. In general though, Apple doesn't really have much on its own old hardware. It doesn't help that the best thing I found was in Apple's own sources. Even for video, versions prior to 9.1 don't even have a OpenFirmware frame buffer video driver.

There's also the rest of the hardware, where crucial components like audio chips and hard drive controllers are seemingly proprietary. On the other, you still have to deal with a pretty capable MMU. On the one hand, this means that 32-bit PPC Macs can only address up to 4 GB, making it relatively feasible on 64-bit machines. Macs themselves also are partially based on the PowerPC Reference Platform (PReP). Doing a G4 is somewhat harder, due to the nature of AltiVec. The MSR (Machine State Register) is hardcoded in Sheepshaver too. Sheepshaver does numerous ROM patches to avoid having to emulate the MMU (or most of the registers involved) at any cost. The PowerPC CPU is rather complex, probably not as bad as a x86 CPU emulator, but definitely not trivial either. I do realize a good chunk of Mac users aren't coders, but that doesn't mean coders won't have a huge number of obstacles too. Popularity aside, there's plenty of technical difficulties regarding Mac emulation.

Since QEMU has is pulling way ahead of Sheepshaver and PearPC in terms of hardware accuracy (it can emulate PPC Mac OS 9.1-10.4), I figured I would have a go at describing the issues of writing a PPC Mac emulator, including by comparing it to the other PPC emulators that are known to be able to run PowerPC Mac OS Classic or X.
