MS. PAC-MAN – DEMO

•

•

The orange ghost's name changed from Clyde to Sue. (Sue would later become a purple female ghost in Pac-Land, appearing alongside Clyde.)

The three intermissions have changed to follow the developing relationship between Pac-Man and Ms. Pac-Man (from when they first meet to having a stork drop off their baby).

Like Pac-Man, Ms. Pac-Man has a bug in the fruit-drawing routine, which renders the 256th board unplayable. While it may be possible to reach the 256th board using the “rack test” cheat available as a DIP switch (usable through MAME or other arcade emulator), the actual arcade hardware will crash at or around the 134th board. At this point in the game, a bug in the code causes invalid data tables to be used for a subroutine which is supposed to draw invisible characters which slow down the ghosts in the tunnels[1]. On level 142, a similar bug causes

a corrupt value to be loaded into the pointer to the maze data, causing the screen to turn black. Although the ghosts and Ms. Pac-Man are still visible, the game becomes unplayable.
