Now that GS emulation has been conquered, what about Amiga
emulation?  It seems to me, from the above, that the "fixed amount"
of resources taken by video would be quite a bit more hefty on an
Amiga emulator than a GS emulator, but...the G3 is so powerful,
why not do it?  Even on an Amiga emulator, I'd think that after you
reach the level of a G3, you'd have enough PowerPC CPU resources
left over after the "fixed" hits from video and sound to make a pretty
fast Amiga emulator...
