i don't recall. it was one of the many 'road apples' (6220 PPC I think) so i wouldn't be suprised to find that apple somehow made it so virtual memory wouldn't work on that model.
note i never said the graphics were _smooth_ or _good _ just the app itself ran fine - e.g. little to no lagging/frozen 'frames'. but that said i can't imaging going back to the original version on a 640x480 display.
