Game Overview:
Announced at the 2003 E3 entertainment conference, Tetra's Trackers was originally planned to be a full-fledged GameCube game that harnessed the power of the connection abilities of the Game Boy Advance.

Here is the official description from Nintendo Power:

"Tetra, the leader of the pirates, has put forth a challenge!

Link must race his way through various settings, collecting stamps from Tetra's pirate cohorts. To rise to the challenge, he will have to use all his exploration and navigation skills. Accepting this hefty task, players search for pirates placed strategically around Pirate Island and receive a stamp from each one as proof that they actually found them. Pirates must be found in the correct order, so players rely upon map information and hints provided by Tetra through the fabled Pirate's Charm. Up to four players compete to see how many stamps they can collect before time runs out.

Features include:

Experience a new level of connectivity between Nintendo GameCube and Game Boy Advance. Compete against one another to prove your skills as trackers.

Control four different colored versions of Link, from the Legend of Zelda series, including characters from The Legend of Zelda: The Wind Waker. Tetra, the young leader of the pirates, guides you as you race to gather stamps from her pirate followers.

Use the Game Boy Advance as a game screen and a controller, and race against up to three friends. Exclusive information appears on each player's screen, while Tetra guides the group along the way with cues that appear on Nintendo GameCube."

The game however, never made to the GameCube. Somewhere along the line in development, Nintendo cancelled the project with no official announcement. The game however, appeared in a different form in the Japanese version of the GameCube game Four Swords Adventures. It was a special game called Navi's Trackers, which never made to North America or Europe in any form.
