Super GPS Pac-Man (cancelled Wonderswan game; 2001)
In the Spring TGS in 2001, Namco showed off a Pac-Man like game for the WonderSwan Color, titled Super GPS Pac-Man. The game would utilize the WonderGate addon, a device that would be able to connect to the DTT Docomo Network. Using the GPS addon, the device would convert the user's current location to a Pac-Man maze, where the player would then use the WonderSwan Color to control Pac-Man and eat pellets. Moving vehicles in the area would act as ghosts.
The game was quietly cancelled, most likely due to the limited success of the WonderGate and that the GPS addon for it was never released.
