The readme links to the Pac-Man Dossier at http://home.comcast.net/~jpittman2/pacman/pacmandossier.html http://home.comcast.net/~jpittman2/pacman/pacmandossier.html which contains an interesting explanation of all the nitty-gritty details about ghost AI and timers. I find it fascinating that there are so many tiny details and variations between levels, which apparently are essential to memorize in order to achieve "perfect play".
