SheepShaver Maximum OS

I heard that SheepShaver only runs up to OS 9.0.4 but has anyone gotten it to run something later?

9.1 not run

Scroll down to Mac_The_Man (very bottom to this page), at Maclife.de/How to install SheepShaver?

Supporting MacOS > 9.0.4 requires to know further internal details of MacOS. In particular the NanoKernel and how it handles the VM. Another difficulty is to proper understand the new NewWorld ROMs format (those based on "Parcels") so that one can decode and execute it correctly. Last but not least is also related to the Apple 68k emulator hooks to communicate to the NanoKernel (i.e. their special HW/VM related opcodes).

Those are the three major issues. I actually had MacOS 9.1 booting almost to the desktop at some point but it was not much useful since it crashed afterwards.

I don't plan to support MacOS > 9.0.4 in the immediate future since I am experimenting with alternative methods to run Classic applications on MacOS X.

PearPC solved the problem, but only runs OS X->

I heard that you could get PearPC to boot into OS 9.2.x, but never actually managed it - it is an urban myth - no OS 9.x support in PearPC.
