I made a custom bluetooth HID controller based on Adafruit’s SNES EZ-Bluetooth project. It works perfectly with my RPi’s BT dongle and all of the emulators… EXCEPT one problem
The bumper buttons (L and R) on the controller do not work in any emulator. They map to keyboard numbers 1 and 2 respectively. Here is the config for the controller in /configs/all/retroarch.cfg
input_player1_joypad_index = 0
input_libretro_device_p1 = 3
input_player1_a = w
input_player1_b = a
input_player1_y = d
input_player1_x = s
input_player1_start = space
input_player1_select = enter
input_player1_l = 1
input_player1_r = 2
input_player1_left = left
input_player1_right = right
input_player1_up = up
input_player1_down = down
input_autodetect_enable = false
I know the buttons work fine because when setting up controls in ES I can map them no problem. The dpad and the 6 other buttons work fine. I’ve tried a lot of configs and done a ton of research but have been unable to resolve it. Ideas?
