Hackers Find F-Zero AX Arcade Game Hidden In Nintendo Gamecube's F-Zero GX

Hackers-Find-F-Zero-Arcade-Game-Hidden-In-Nintendo-Gamecube-F-Zero-GXIn 2003 Nintendo released the highly anticipated follow up to their futuristic racing series with F-Zero GX. Upon release, the game also sped into the arcades with F-Zero AX, an adapted version of the game. Although it was assumed these were different games, the arcade game has been found sat dormant within F-Zero GX and is very much accessible.

If you've managed to play F-Zero AX in the arcades, you're quite the lucky one - very few of these machines still seem to be in use today. F-Zero AX utilised the Triforce arcade system board which was a joint creation between by Namco, Sega, and Nintendo, which was effectively hardware based upon the Nintendo Gamecube.

This similarity between hardware enabled Nintendo to develop both F-Zero GX and AX at the same time. During development, AX was given a selection of exclusive tracks which could be obtained on GX by inserting your Gamecube memory card into the arcade machine. Upon downloading this additional data, the Gamecube version of the game would then grant access to the hidden AX cup.

While many of us have been content with F-Zero GX and its many offerings, others have since decided to dig deeper into the decade old game. Upon doing so, they managed to strike gold. Not only were the previously mentioned unlockable AX race tracks included within retail copies of the Gamecube game, but also the entire F-Zero AX arcade game too, in a fully playable form.

This hidden version of the game, of course, features the much loved timed-arcade-gameplay into the high speed racer, along with the many different coin-op screens not present in the retail version. Gamers can now enjoy a whole new dimension to F-Zero GX at home in true coin-op style. Suddenly the lack of AX machines out in the wild isn't as upsetting.

So how do you go about enjoying this arcade treat? All you need is the Nintendo Gamecube Action Replay or Gameshark and the PAL or NTSC version of F-Zero GX. Using the codes below, you'll be granted access to this hidden portion of the game:

Amazing! I think I'll have to try that out in the next few days, even now people are still cracking Action Replay codes for old games out! Great stuff! :-)

May be worthwhile pointing out that there are only certain Action Replay devices that will be able to access this? As the newer versions had the facility to enter your own codes removed IIRC? Can't check till I get home, but I am 99% certain :-?

I've got the older version of the Action Replay (PAL), where I can enter & save codes so mine should be fine.

Although I think it said the US early releases of the Action Replay didn't work with the code?

The NTSC code works.

The PAL code is what my early US release Action Replay didn't accept, I tried that even though I don't own a PAL console or game version.

I played the arcade ver. a long time ago.
The unit was large, and designed for F-Zero AX.
The arcade unit had a GameCube memory card slot. Meaning arcade data could be used in the GameCube version, and vice versa.

Too bad no one can find Mario Kart Arcade GP in any of the home console games.
Ever since I got to play Mario Kart Arcade GP every single home console version just doesn't cut it.
This was another dedicated arcade machine, so it would have been difficult to use it for other titles.
This one also had the GameCube memory card slot. Although, with Mario Kart Double Dash being so different from the Arcade game, I'm not sure how the data was used.
Mario Kart Wii came close to giving the gameplay and experience of the arcade unit with the wheel controller, but the tracks and cars just didn't compare at all.
I'm hoping Nintendo can manage to build something worthy for the Wii U.

I think there's still a F-Zero GX cab in Blackburn.

I remember now that the Player 1 seat had a messed up wheel or something, like no force feedback or going to a neutral straight position. Hence the Player 2 seating.

This would be too good to be true - but - has anyone tried this with 2GCs linked using the BB adaptor???
