Oooooh, FUUUUCK. I had to test Biff on my Apple IIgs, which is a US Apple IIgs at 60Hz, to *finally* think of the fact that the puck and opponents are faster at 60Hz than at 50.
Either I patched EVERY delta to account for the 20% difference (and it fucked up A LOT of cases where rounding errors made an opponent too easy or too hard), or ....
I went the easy way, and I drop 1 frame out of 6 at 60Hz.
