I have small question: Can sheepshaver be ported to MorphOS ? I know that without mmu api it can't be done but maybe someone from Morphos Team could do it.

It is not feasible with a shared address space OS. I can not remember details anymore but I looked into it years ago and decided it is not possible without PPC emulator.

I think it would require a function that remapped ram with the MMU while the emulated mac task is running. Other option is leaving empty the memory areas used by rom and also the first kbytes of ram.

To switch from the emulated mac to the host OS a non existant instruction could be used to raise an exception.

I don't think it's possible right now with MorphOS.

i wonder how shapeshifter/fusion were possible back then? coz of mmu existed or what?

They used PrepareEmul to preserve low mem space for Mac OS.

does morphos kernel can alloc this mem for shapeshifter/bassilisk without 68k emu?

It cant. It is reserved for the OS (some other stuff is there, IIRC).

But I recall low mem space was not only remap issue.
