Merci pour les informations mais ce n'est pas notre priorité pour le moment d'inclure un pilote peu utilisé.
Nous regarderons dès que nous aurons un moment.

Hello

@stealth La j'avoue que je n'en sais rien. J'ai un 3b+ et une alim aukru, aucun souci de sous voltage.

I can't talk about the SFC30, wich should emulate a real SNES controller. But for the NES30 Pro, I got what I expected... although I can't compare it with the original NES controller anymore, from what I remember, the feel is the same for the D-pad. I also have the 8bitdo Zero and the D-pad there is smoother (better for most people), but those don't try to be a sort-of improved replica.
It's a pitty for the SFC30, but if you want the a full button sized NES like Controller, imo there is nothing better than the NES30 Pro.
