@gaz12 ce pad marche. Je l'ai, et j'en ai intégré sa config dans recalbox il y a 2 ans ...

I think we are speaking about two different things. There is a problem with joystick/analog stick calibration/deadzone in general with recalbox.
At the moment I am able to drive 'assetto corsa' on PC with my xbox360 pad quite well (steering help etc. turned off of course).
In Recalbox I am not even able to play Mariokart 64 mit analog stick since the deadzone/calibration issue.

Hi pal, should be corrected in 3.3.0. For now you're stuck.
