Try and run just the beginning of a very basic pattern that goes to the bottom of the screen then runs a square around the whole first screen. The ghosts won't behave the same each time since it isn't humanly possible to have all of your joystick presses start and end in exactly the same 1/60th of a second each time you run the pattern. CFP patterns on Pac-Man or PacPlus aren't very hard to run since you just have to pre-turn every corner, but patterning Ms Pac would require frame perfect patterns of joystick input which only a program or bot could do.Originally Posted by anningmay
That said, I do think it is interesting that "restarting" the machine before starting a game, which some players suggest should be a requirement for all submissions, does make some games easier to pattern, with or without Free-Play. Berzerk and a lot of trivia games are other examples.
