In 2013 it was discovered that F-Zero GX for the Gamecube also contains the full arcade F-Zero AX game.
This patch will make your F-Zero GX .iso boot directly into that hidden version without the use of codes.
Use https://www.romhacking.net/utilities/704/ or any other xdelta utility to patch your iso!
Based on the main.dol patch by Ralf from the now defunct GSCentral.
