I solved it...

3 days... and 4 reinstall later... I realized that I only tested the buttons with the same rom. I tried another rom and it works...

I think the rom is broken but thanks for your help

At first start of recalbox, I configured the gamepad in emulationstation, could this cause the problem?

Hello,

I'd like to play some games in the SNES emulator.

I setup all buttons for the Xbox controller and the keyboard and everything works fine but the shoulder buttons (L1 / R1).

I use the xboxdrv Option and testet to map the buttons in the retroarch menu too but nothing works. The same problem appears with the keyboard and another simply USB-Controller too.

I there a solution for my problem?

Thank you
