Wii classic controller linked by Wii remote controller to Rpi5

[dedebatou]

Hi all,
I'm trying to use a Wii classic controller for my recalbox.
I've connected it to the connector of a Wii remote controller (already appaired by bluetooth).
This new controller is correctly found by the recalbox and I can perform the controller settings.
It's almost perfect but ... When I load a game the controller doesn't work ! There isn't any button that work.

Any idea ?
