Did you have any luck with that?
Via MacMame on my Sawtooth:
Found myself well and truly out of practice with this - even with the difficulty set to normal. I'd love to compile an up to date Mac PPC command line release of MAME that is compatible with Tiger that could be shared for all to enjoy. This isn't my field but I'm willing to give it a try. Would anyone be prepared to give me guidance if I decided to take a stab at it?
About the Amnesia's.
Well I really tried hard(all the beta builds available to me of leopard) - in the early ones the game doesn't open at all and in the later - it crashes after the title screen and when the actual game should begin. Then the next build behave exactly the same as the latest 10.5.8.
I just upgraded to Geforce 6800 Ultra and although now the game doesn't hard freeze any few minutes it hard lags any few minutes with not fully utilized CPU (max at 75%) so it looks like it needs even more powerful GPU. I've ordered one BFG 7800gs for cheap but I don't know if it'll work since it's untested and then I've to flash it.
