It's compiled for 68040+, however it crawls along very slowly on my A1200/060, realistically you would need a PowerPC. On a P4/2400 running WinUAE it is still not full speed but is more or less playable. I would imagine it would easily reach full speed under Amithlon or similar.
It seems that the only fast emulators for low-end Amigas are the ones written in assembler, the ones written in C are just too slow, as a general observation.
