F-ZERO GX Hidden Command Unlocks F-ZERO AX Content
The F-ZERO AX content has sat behind arcade hardware and memory card linking for 23 years, so a portable command that works on the current Nintendo Classics release turns a dead unlock path into something anyone with four controllers can attempt.
Reporting from 1 source: Game Spark.
A hidden command that unlocks F-ZERO AX machines, cups, and event-distributed custom machine parts in F-ZERO GX has been reported on X. The GameCube racing game, released in 2003, originally required a memory card link to an arcade cabinet or similarly difficult conditions to access that content. Some commands require four controllers with simultaneous input. The command reportedly works on both the original GameCube release and the Nintendo GameCube Nintendo Classics version available to Nintendo Switch Online + Expansion Pack subscribers on Switch 2.
The F-ZERO AX content in F-ZERO GX was never meant to be easy to reach. Courses and machines from the Sega-built arcade motion simulator required linking a GameCube memory card to the cabinet, or conditions the source describes as nearly impossible today. The command circulating on X bypasses that path, opening the AX machines and cups plus custom machine parts that were given out at events.
The original 2003 GameCube release and the Nintendo GameCube Nintendo Classics version on Switch 2 both appear to accept the command. Input requires four controllers connected at once for some of the sequences, so the barrier has shifted from hardware access to coordination.
