Navi Trackers

Navi Trackers is a game mode in the Japanese version of Four Swords Adventures. Originally planned as a standalone game, the name was originally titled Tetra Trackers. Up to 4 players are able to connect their Game Boy Advances to the Gamecube's controller ports and compete against each other. The object of the mini-game is to run through mazes, searching for members of Tetra's crew and collect stamps in a certain amount of time. The actual game takes place on the Game Boy Advance screen while a basic map and the narration of the action by Tetra appears on the television screen. You are also able to play solo, to collect alone, or against a CPU Tingle. It is unclear as to why the feature was not included in Four Swords Adventures outside of Japan, but many believe it to be that it was due to problems with localization.
