Homebrew Button remap on classic controller for n64 vc

[vdeolive]

Hello,

I am trying to play mario kart vc game on my softmoded wii.

I am using a classic controller but it seems that the button mapping is not correct. In the vc electronic manual, n64 b button correspond to classic b button. But in game, n64 b button is working on y classic controller which makes the game unplayable (accelerate on a button / fire on y).

Is there's any way to remap correctly the buttons on classic controller please?

Thanking you
