The last “major” F-Zero game released was back in the Gamecube, the sterling, yet extraordinarily challenging, F-Zero GX. What tends to be less remembered was it was a dual release. At around the same time, Sega released on Nintendo’s TRIFORCE hardware an arcade version called F-Zero AX. In the US arcades were pretty moribund around that time, so it tends to be a lot less recognized on these shores. The AX machine bore a Gamecube memory card slot so that players could take their save files to the arcade unit and use their custom vehicles there, and take data from that version back home. The AX version also has tracks and vehicles not in the GX version.
What tends to be even less well known is that nearly the entire arcade version of F-Zero AX is right there on the Gamecube disk! Back in 2021, Romhacker Elfor constructed a patch for the Gamecube version that, if played in an emulator or somehow made readable by GC hardware, can boot directly into that version of the game.
There are some differences from the arcade version in this revealed version of game, many of them related to music tracks left off the disk. More recently, Anthony Ryuki made a patch to restore those tracks, and bring the Gamecube AX version even closer to the arcade experience.
