(BTW, 10 times faster than an 060 on a 1.2 Athlon is NOT that fast )
Actually, it is. You must remember that all Amiga emulators are emulating a different processor as well as the Amiga's custom chips, which requires some grunt
Wait! No. That's wrong. You're right. The base Amiga has already been emulated, therefore an 060 shouldn't require a 1.2 Athlon since it's only a few more instructions which need to be emulated...
Or maybe my first theory was right.....BLEH! Take your pick
