PPC Emulator, is this real?!?!

[Marcelo A. Ferreira Gomes]

Not so simple. I haven't looked into this particular emulator yet, 
but most engines just take "shortcuts" when dealing with speed issues 
by not properly emulating the full behavior of the MMU, thus getting 
the speed they need. They might be all that's required to emulate a 
game console, but a full-blown operating system usually requires much 
more from the MMU.

If this GC emulator is like that, we'd have to make massive changes 
to many parts of the code in order to properly emulate the MMU, and 
it would probably be harder than writing an emulator yourself from 
scratch.

I may have some time this weekend to take a look at this issue. Later 
on, I'll tell you what I've found. If someone else has some spare 
time before me, please look into it, too, and spread the word.

[]s.
