Actually, using SheepShaver (which is no different than Apple's Classic environment and in some ways better), I can easily do all of that under Snow Leopard, probably faster than on your G5. :beige:... Let's see you do THAT Snow Leopard...
SheepShaver is way different from the Classic environment.
I also seriously doubt that an Intel Mac running SheepShaver (emulating a PPC) is faster than a G5 running SheepShaver that merely passes instructions through. On the other hand, Basilisk II may be faster on Intel than it is on PPC, since either one emulates, and the Intel Mac would probably be faster, unless it's something like a Dual 2.7 G5 vs a Dual 1.83 Intel.
