vMac is very good at the Mac 68K side, and PearPC is a quarter-baked start to running PPC OS X (circa Jaguar) on Intel (Windows). This is why it's better to find a good all '68K' Mac emulator or an all 'PPC' emulator. not in Apple Public source license) and it requires a native PowerPC processor to run the 68K emulator and PPC CPU pass-through virtualization. In short, Classic is an Apple-thing, not open-source (e.g. Classic even has it's own Mac manufacturing code.Īpple purged a lot of 68K code in MacOS 8.5, but I'm not sure if they ever reached 100% PowerPC code in OS 9.2.2, that's one reason for OS X to begin with. TrueBlu besides not written for Xcode, could be re-compiled for Intel but it's main value is virtualizing a PowerPC-Mac capable of running MacOS. The 68K nanokernel is so complete the original PPC Macs could even boot 68K MacOS with no modifications - that's a feat of engineering. This means anything like drivers, extensions, applications, could be mixed 68K/PowerPC. Embedded in OS 9 is a 68K nanokernel emulator which allows it to run a mixed-architecture execution environment, even on the stack.
TrueBlue is a proper OS X app which provided emulation of a MacOS 9 machine, it does not provide OS 9 itself. I think it was more like VMware but for a single purpose and only for PowerPC chips. As for running Classic, I don't think TrueBlu was even a proper emulator.
