This is a hack of "Pac-Man
" where the programming of the game is made to work on the hardware of a "Galaxian
" machine instead of the original hardware. Galaxian is an older game, and therefore not quite as capable of displaying the game properly. When ghosts are eaten, and return to the ghost pen, you see everything except for their eyes. Presumably, this bootleg was created and purchased primarily due to its lower cost, or operator naivety.
It has different colors and screen proportions. Credit, level, and lives remaining are incorporated in the maze section (look at the middle exits). The sound is also quite a bit different. In addition, the ghosts are introduced by PuckMan's 'Alternate' ghost names, and there is no dip switch for ghost names.
