Cat Trax began life as a straight Pac-Man clone, called Crazy Gobbler for the Emerson Arcadia 2001 system. Before its American release, the Pac-Man and ghost sprites were changed into cats and dogs, to avoid the kind of legal problems which were brought by official home licencee Atari upon Philips/Magnavox for its K.C. Munchkin! game. The original Gobbler version was published in Europe, alongside the cats-and-dogs version.
The Atari 2600 version never saw a full release, instead only showing up in a 128-in-1 cartridge under the title Cat and Mouse, and was in 2003 re-issued on its own by Atariage.
UA Limited, who made this game, made several other more or less orthodox Pac-Man clones for the Arcadia and its various related systems, and often reused code between the games. Add
