I remember reading a while ago about some PAL Game Cube games like Sonic Heroes running faster (not more fluid) in 60Hz mode than in 50, due to some sloppy programming on Sonic Team's part (not sure if they just sped up the same stuff that was shown at 50Hz, or something). As far as I remember, it meant that some voices started playing earlier than they should, the timers run faster than normal, and there were times where the button presses didn't register. Does anybody remember which of these featured that terrible bug? It will be quite useful when getting the "best" 60Hz versions of these games (latest builds with more languages, etc). I think Sonic Adventure DX didn't have it, while Billy Hatcher was another one of them.
