Gamecube to PC controller preset

[jabu2oz]

Here's a fairly complete actionMap preset for a Gamecube to PC USB converter; Joybox 13.

Download Gamecube actionMapPreset8.xml

Go to "C:\Program Files\Codemasters\GRID\ActionMap", backup actionMapPreset4.xml and overwrite this preset with it (or add a new reference to it in actionMapPaths.xml).

I'm having two problems with it at present (which I hope someone can help with):

1. Accelerate and brake is stuck slightly on (one "block"). Sounds to me like it could be something to do with deadZone, but I'm not sure how to fix this.
2. In the menu, the Menu Up (D-Pad Up) is stuck on. Unplugging/Replugging the controller fixes this, but thats not particularly elegant.
3. The rumble is constantly on in game.

Any help would be appreciated!
