…appeared on the Internet. The Top Secret Document contains every know information, that is about PacMan. For example, just examine the lesser knows facts about the design of the levels and the mysterious level 256 in Pac Man. From the document:

Pac-Man was always meant to be a game with no ending. The developers at Namco mistakenly assumed the game’s increasing difficulty was sufficient to prevent anyone from playing indefinitely. Of course, within a few years of Pac-Man’s release, players had discovered that every level beyond the 21st was identical. Patterns were quickly created to exploit this fact and, for any player able to get past the first 20 levels, the game now became a test of endurance to see how many points you could rack up before losing focus and making a mistake. High scores soared into the millions and most players agreed the game simply went on forever. Eventually, a few highly-skilled players were able to complete 255 consecutive levels of play (scoring over three million points and taking several hours to accomplish) and found a surprise waiting for them on level 256. It was a surprise no one knew about-not even the developers at Namco.

The 256th level displays the left half of the maze correctly, but the right half is a jumbled mess of randomly colored letters, numbers, and symbols. Notice the bonus counter in the lower-right of the screen is also malfunctioning. The left side of the maze plays normally, but the right side is a different story. Although both the player and the ghosts can navigate through the right half of the screen, the original maze walls no longer apply. Instead, Pac-Man must be guided through a confusing series of open areas, tunnels, one-way intersections, lone walls, and pass-throughs-all invisible to the player-while four ghosts are in hot pursuit.

You definitely want to know all this things about PacMan. The reason for the “malfunctioning level” i.e. lies in a internal counter error. Just keep on reading on the dossiers site. They also got extensive information about the enemy-characters as well.
