There is also currently no way to even virtualize BeOS for PowerPC. I wish there was. The closest I have seen is a MESS that could boot and show the boot splash screen (this is a 3d Be logo on PowerPC, the one you see on Intel was only ever on Intel.) The dingusppc have BeOS as a possible target for their Mac emulation, but it is not there yet. I'm pretty sure QEMU can't boot BeOS because BeOS requires an old world ROM and it requires a PCI Mac with a 603 or 604 processor - so a 4400, 7300, 8500/8600, 9500/9600 and a few others (including clones) work - but nothing NUBUS and nothing post the first motherboard revision of the 8600/9600. The later x600's have a different motherboard and do not work. Nothing that shipped with a G3 and nothing with new world ROM.
