All the Pac-patterns sites I have seen have the same ones, which are only good on slow Pac-Man.
I have developed an awesome fast Pac-Man pattern (clears 2/3rds of the board, Apple stage and above), but I have yet to find a way to make it clear the whole screen the SAME WAY each time, once I do I will put it out there. The pattern is good, 2/3rds of the screen cleared (and even works on pre-apple stages with one change), but it unfortunately needs about 6 different endings (cycles through them depending on how long the ghosts stay blue), but I still need to get it up to do everything except the power pellet corners and get the 2nd bonus fruit in there.
