After 23 years, one extraordinarily dedicated F-Zero GX player has solved a mystery that the community had long considered unsolvable. A Japanese player known as BTEST4HE has uncovered hidden cheat codes buried in the 2003 GameCube release since day one, unlocking the game’s fabled event-only Gold Parts.
The discovery rewrites what fans thought they knew about one of Nintendo’s most beloved racing games and brings closure to a hunt that has persisted for more than two decades.
The White Whale of F-Zero GX
F-Zero GX’s fan-dubbed Gold Parts have been a kind of white whale for the community since the game launched. These special components could originally only be unlocked by attending in-person promotional events in Japan — limited-time gatherings that ended more than 20 years ago. Outside of homebrew modifications, the parts were widely considered lost to time.
The conventional wisdom held that these exclusive components were simply inaccessible to anyone who did not attend the original events. The codes themselves were never documented in any official capacity, and no amount of button-mashing or memory-card trickery had ever revealed them.
Universal compatibility: The cheat codes work on every version of F-Zero GX — original GameCube, Nintendo Wii, and even the Nintendo Classics version on Nintendo Switch 2 — regardless of region.
BTEST4HE changed all of that. In a post on X, the player revealed eight unique cheat codes that can be input on any version of F-Zero GX, each unlocking specific sets of parts available for purchase in the in-game shop. The discovery works regardless of whether you are playing the English or Japanese version, and it is not system-dependent.
The Four-Controller Catch
There is a significant caveat. Five of the eight codes, including the ones that unlock the mythical Gold Parts, require inputting commands using four controllers simultaneously. In practical terms, that means you need either three friends or an unusual number of arms to pull off the input sequence.
The codes work on the original GameCube version, the Nintendo Wii version, and even the Nintendo Classics version on the Nintendo Switch 2.
The three remaining codes can be entered with a single controller, making them considerably more accessible. These still unlock valuable parts, but the most coveted Gold Parts demand the full four-controller setup — a fitting challenge for a game defined by its extreme difficulty.
How Was This Found?
The question on everyone’s mind is how BTEST4HE managed to uncover codes that had eluded the community for 23 years. The discovery process has not been fully documented, but the achievement speaks to a level of dedication that goes beyond typical gameplay. Whether through systematic code auditing, memory inspection, or sheer persistence, the result is a genuine piece of gaming archaeology.
The F-Zero community has responded with a mixture of excitement and disbelief. For a game that has not received a mainline sequel in over two decades, any new discovery generates significant attention. The Gold Parts, in particular, carry a legendary status among fans who have spent years theorising about their existence and accessibility.
A Legacy Preserved
F-Zero GX remains one of the most celebrated racing games ever made. Developed by Amusement Vision (now Sega’s studio behind the Yakuza series) in collaboration with Nintendo, the GameCube title pushed the system to its limits with blistering speeds and intricate track design. The game’s difficulty curve is notorious, with later courses demanding precision and reflexes that few players can muster.
The Gold Parts were always meant to be exclusive rewards for dedicated fans who attended Nintendo’s promotional events. Their inaccessibility over the past two decades added to their mystique. Now, anyone with a copy of F-Zero GX and enough controllers can experience content that was effectively lost for a generation.
The discovery also highlights the importance of preservation communities. Fan sites like CrazyGameNERD have maintained detailed documentation of F-Zero GX’s mechanics and secrets for years. Without that institutional knowledge, BTEST4HE’s discovery might never have been possible — or at least never been properly contextualised.
What Comes Next
The immediate question is whether Nintendo will acknowledge the discovery or take any action. Given that the codes have existed in the game since its 2003 release and work on official re-releases including the Nintendo Classics version, it seems unlikely that any intervention is forthcoming. The codes are part of the game’s codebase, not exploits or modifications.
For the F-Zero community, the discovery is a reminder that even well-explored games can still yield secrets. Twenty-three years after release, F-Zero GX continues to surprise its most dedicated players. Whether this sparks renewed interest in the franchise or simply provides closure for long-time fans, BTEST4HE’s achievement stands as a testament to the enduring appeal of Nintendo’s fastest racing series.
The Gold Parts are no longer lost. They are, quite literally, part of the game — exactly as they were always meant to be, waiting for someone patient enough to find them.
