F-Zero GX cheat codes reveal Gold Parts after 23 years

• The discovery is credited to Japanese player BTEST4HE, who posted on October 9, 2026 about hidden commands for F-ZERO GX (GFZJ01).
• According to Kotaku, there are eight unique cheat codes, but the exact button combinations and unlocks are not fully visible in the available source information.

What happened

Kotaku says that after 23 years, a new way has been found to unlock content in F-Zero GX. The cheat codes reportedly unlock the previously event-only Gold Parts, which were not normally available through standard progression. In the available source material, the discovery is linked to a Kotaku article titled New Cheat Codes For F-Zero GX’s Gold Parts Have Been Discovered After 23 Years.

The discovery is tied in the source to Japanese player BTEST4HE. In a post on X dated October 9, 2026, the user says hidden commands for F-ZERO GX (GFZJ01) have been found. The same post also says recognition of the 1P controller command and the Thunderstorm command has been confirmed in Nintendo GameCube Nintendo Classics. That is the concrete, directly visible source for the claim that the commands have at least been recognized in that environment.

Kotaku also reports that the codes are said to work across multiple versions of the game, including English and Japanese releases, and mentions support for the original GameCube version, the Wii version, and Nintendo Classics. However, those version claims are not fully spelled out in the source information provided here, so the discovery itself and the link to BTEST4HE are the most firmly supported details. The available evidence does show that the post explicitly refers to F-ZERO GX (GFZJ01) and to recognition of specific commands, but not to the full list of eight codes.

The fact report also says Kotaku frames the find as the solution to a long-running F-Zero GX mystery after 23 years. That timeframe matches the game’s original release year, 2003, and explains why the discovery is being treated as notable within the community. The source information also describes the Gold Parts as event-only, which adds to the significance of the find.

Background

The Gold Parts are described in the source material as event-only content. That makes the discovery relevant to the F-Zero GX community, since these are parts that had long been seen as difficult or not normally accessible. The fact report explicitly says Kotaku presents the find as solving a long-running puzzle around the game, and that the discovery comes 23 years after release.

The available information mentions eight unique cheat codes, but does not provide the full list or the exact link between each code and each part. It is also unclear on which hardware or software environment BTEST4HE performed the tests, beyond the reference to Nintendo GameCube Nintendo Classics in the X post. The post text only says recognition of the 1P controller command and the Thunderstorm command has been confirmed; that does not automatically mean all eight codes have already been fully documented in the source material provided here.

The fact report further says Kotaku claims the codes work across multiple versions of the game, including English and Japanese releases, plus the original GameCube version, the Wii version, and Nintendo Classics. Because the source information is incomplete on that point, that broad compatibility should be treated cautiously. The safest conclusion is that the discovery is tied to F-ZERO GX (GFZJ01) and that there is at least one confirmation mentioned for Nintendo GameCube Nintendo Classics.

The external context provided also points to broader community interest in the Gold Parts and other unlockables in F-Zero GX. A ResetEra thread describes the find as a way to unlock “everything” in the game, including the previously inaccessible gold parts, though that is a community summary rather than a primary source. A Reddit thread about event-only custom parts shows that players have long been looking for ways to obtain such items, which helps explain the context of this discovery without adding new facts to the core claim.
