Ok, whatever, if it makes sense to you have at it. I still see little gain
but if it sounds like fun go try to write it, and let us know if it works.

I still think it's too much work for too little gain -- especially
given all the questions about whether PPC has a future. Will your
emulator run within user space? If so then an architecture switch
might not hurt you, but you can expect it to run slowly. If however
it runs in the kernel and has to poke at the hardware, then a processor
switch will hurt if Apple moves to something else (Intel, IBM/PPC,
whatever) and your optimized emulator was tuned to run on Motorola/PPC.

How likely is a processor switch? Beats me. But it's enough of a
possibility that I for one wouldn't want to take on a project as
ambitious as this hardware emulator you're talking about if all
that work could be nullified sooner or later...
