I am having this SAME problem but with my keyboard…
Retropie 3.0 on RPI 2
Xbox 360 wireless controller works perfectly in emulationstation and let’s me configure the buttons, but once I boot PSX Emulator, it does not respond.
EDIT:
I changed:
/opt/retropie/configs/all/retroarch.cfg
input_autodetect_enable = false (and set it to true)
This allowed my xbox 360 controller to be detected when starting the emulator, however, now I am having issues with the button mapping. It changes the button configurations
My ‘A’ Button on the controller is now mapped as the PSX ‘O’ button.. and the ‘B’ Button is mapped as PSX ‘X’ button. the other two are switched around as well. I have tried to ‘trick’ the button mapping, but it still puts them back to that setting.
Help would be appreciated
