Are you talking about pseudo little-endian mode on a G3/G4? Make no mistakes 
that would speed up the emulation by about 30/50% ( Atleast it did on Virtual 
PC )
I've been asking about this before but got no replies from here at all.
Also..........since QEMU-fast only works on a modified Linux kernel and makes 
QEMU about 50% faster ( atleast that's what the website says ) is there a way 
to make QEMU-fast work on WINDOWS/95/98/2000/NT/XP to? I suppose Virtual PC 
does this somehow. No idea how though..........
