Tools = mmu.library.
What you are describing is tricky... You have to create a complete
virtual machine under AmigaOS. The main problem is emulating the
hardware. Every access to a hardware register by the CPU would
generate a MMU exception (which are quiet expensive). Considering
there's possibly thousands a second (e.g. every blit, interrupt or
even context switch). There would be a big slowdown.
Still, it's possible. When you're done you can tell me I was wrong!
This could also be used for a Atari ST or Genesis emulator.
