Some problems with controls

[MerguezAuRIz]

I used a dualshock to play to smbx but I change accidently my controls and I selected two actions for one button. Result: my controls are literally dead...
Have you some idees how i can reset my controls without using the game ? Thanks

Have you tried JoytoKey.exe?

Try unplugging the controller and then try to boot up the game, that may reset the controls to Keyboard, so you can setup your Joystick again.
