Hello buzz.
Thank you very much for your help!
I did the following:
1. Accses Retropie via puTTY
2. typed in cd RetroPie-Setup
3. typed in sudo ./retropie_setup.sh
4. then under No. 5 i picked the retroarch-RETROARCH
5. Picked binary.
6. performed a reboot.
After that my controller didnt work in the game at all!
I couldn’t use a single button ingame. Emulationstation worked fine though.
I pluged in my keyboard but it did not work either so i had to pull the plug.
After that I reconfigured my gamepad but it still did not work in game and I had to pull the plug again.
Do I need to do the binary and script update again?
If I did something wrong please tell me because i am very new to linux and often not sure what to do and how.
