I suppose "incomplete" depends on what you're doing. It worked pretty well for playing around with all those years ago, and it at least still compiles. I don't have any PPC images around to throw at it.

Well, if you need another PPC Mac OS X emulator, look at QEMU. QEMU's Mac PPC support has improved by leaps and bounds recently. It's now a pretty competent Mac emulator for OS 9.0-10.5.

It was dead for a number of years, but then revived again but now nothing for a couple of years.

One of the devs who was working on it has been improving qemus PPC emulation in the meantime though.
