Aaron associates this to 8-bit mode support dropping, but discrete sound was also added about this time as well (not a pacman issue, but in general).Ġ.63 was slower than 0.61, which Aaron attributes to the newer. Not comprehensive enough to give you overall guidance, but it might show some trends.Īlso, Aaron has a lot of good info on his blog linked above: Not sure I agree with all his conclusions, or how well pacman speeds compare with newer games, but:Ġ.53 was slower than 37b16. Has a long list of performance of different games with different versions and processors.
