Pac-Man uses a software-based random number generator. I made a video all about it, which you can check out below. The game uses it only to determine what directions frightened ghosts move throughout the maze.

Thumbnail for the video 'How Frightened Ghosts Decide Where to Go'I feel like I've referenced this video once already...

Ms. Pac-Man reuses that same random number generator for the same purpose. However, it also has another source of randomness that it uses for a few other purposes. Today we'll look at one of them! This slight modification changed how top-level players play the game, and why you don't see any "perfect games" of Ms. Pac-Man.

That gif included in the post is delightful, and I hope inspires some sicko to create "Pac-Man Vs. 99"

Yes, Ms. Pac also uses the R register for fruit selection, calculating (R % 32) % 7. There is a 5/32 chance of getting a cherry, strawberry, orange, or pretzel, and a 4/32 chance of getting an apple, pear, or banana.
