F-ZERO GX Hidden Command Unlocks F-ZERO AX Content
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.
