F-Zero GX Players Discover Hidden Unlock Codes That Apparently Require Four Controllers and Several Extra Hands

F-Zero GX players uncover secret button combinations unlocking AX courses, AX racers, and Gold Parts, working on original GameCube and Nintendo Classics.

More than two decades after its original GameCube release, F-Zero GX is still revealing secrets. The game's dedicated community has documented previously unknown button combinations that unlock additional vehicles, courses and custom-machine components. The discoveries received wider coverage on October 12 and have reportedly been confirmed to function in both the original GameCube edition and the Nintendo Switch 2 Nintendo Classics version. Some codes are relatively straightforward, requiring sequences entered through a single controller to unlock AX courses, AX machines or particular vehicles. Others are considerably more demanding. Several valuable Gold Parts can apparently be unlocked only by entering specific combinations simultaneously across four controllers. That unusual requirement presents a practical challenge for anyone who does not happen to possess four functioning hands. Enthusiasts have suggested coordinating multiple players or experimenting with alternative controller arrangements. The discoveries are particularly valuable because some of these components were previously associated with cheat devices or other less convenient unlocking methods. F-Zero GX originally launched in 2003 as a collaboration involving Nintendo and Sega's Amusement Vision team. Its blistering speed, demanding handling and substantial content made it one of the GameCube's most technically impressive racing games. The new codes demonstrate that even extensively studied commercial releases can retain undocumented features for decades. They also provide another reason to revisit the game through Nintendo's modern classic-game service. Players should remember that these discoveries do not constitute a new game update or downloadable expansion. The functionality was apparently hiding inside the original software all along. Nintendo's developers simply expected players to possess an unusually cooperative group of friends.
