Wired nintendo switch controller not working in game

Are you sure you haven't disabled the EmulationStation input auto-configuration ?

You can check if the configuration for the gamepad has been created, following your input configuration in EmulationStation, in the /opt/retropie/configs/al/retroarch-joypads folder. Same folder can be accessed via file shares at \\retropie\configs\all\retroarch-joypads and it should contain a .cfg file named similarly to your gamepad.

I have a .cfg file

[makatack]

What should I try now?

[mitu]

@makatack Can you post the contents of the .cfg file here ?

[makatack]

@mitu hi sorry just checking again should the .cig file be in configuration editor - advanced - Liberty options

[mitu]

@makatack No, I was referring to the .cfg file that should be found in \\retropie\configs\all\retroarch-joypads.
That is the file which RetroArch uses to configure the gamepad. Do you have a file there ? If so, you can open it with Notepad or other text editor and copy the contents, then paste the copied content here in the topic.

@mitu I am not quite sure on how to do that

[mitu]

@makatack Can you access your RetroPie via File Shares from your PC ? Then the same method can be used to access the configurations (the shared \\retropie\configs folder), where the gamepad configuration file is saved.

How did you copy the ROM file to you RetroPie installation ?

[makatack]

@mitu i copied it with usb

Is your Pi is not connected to the internet/network/WiFi ? You may try accessing it from your PC, as described in the File Shares page, this way you'll be able to find the file in question.
Try reconfiguring again your gamepad from EmulationStation, from the EmulationStation menu (accessible pressing the Start button), go to Configure Input and re-configure the gamepad. See if that changes anything when you start the game.
