It looks like F-Zero AX is not playable without Quadforce. Nintendo Life posted earlier that the game can be played via Action Replay cheats.
I converted the AR codes to Ocarina/WiiRD to use on USB LoaderGX for the NTSC version and it works like a charm. The game still boots up as GX but once you hit start, it kicks into AX Arcade mode.
For anyone interested, heres the Ocarina/WiiRD code for the NTSC version (Didn't convert the code for the PAL version but you can find the AR code in the link above and convert it using this tutorial.)
