Reply To: Problem configuring joystick and buttons

[voltron2112]

This is what I would try. First type

jstest /dev/input/js0

this will let you see what buttons are being pushed on the joystick, so write down what each button number is associated with, and the axis’s of your joystick.

ctrl-c exits the jstest

Now you need to edit /RetroPie/configs/all/retroarch.cfg manually with the correct button numbers you found using jstest. Here is an example of mine. The last two lines are so I can press two buttons to exit the emulation.

input_player1_joypad_index = "0"
input_player1_a_btn = "0"
input_player1_b_btn = "1"
input_player1_y_btn = "3"
input_player1_x_btn = "2"
input_player1_start_btn = "7"
input_player1_select_btn = "6"
input_player1_l_btn = "4"
input_player1_r_btn = "5"
input_player1_up_axis = "-1"
input_player1_down_axis = "+1"
input_player1_left_axis = "-0"
input_player1_right_axis = "+0"
#input_player1_l2_btn =
#input_player1_r2_btn =
#input_player1_l3_btn =
#input_player1_r3_btn =

input_player2_joypad_index = "1"
input_player2_a_btn = "0"
input_player2_b_btn = "1"
input_player2_y_btn = "3"
input_player2_x_btn = "2"
input_player2_start_btn = "7"
input_player2_select_btn = "6"
input_player2_l_btn = "4"
input_player2_r_btn = "5"
input_player2_up_axis = "-1"
input_player2_down_axis = "+1"
input_player2_left_axis = "-0"
input_player2_right_axis = "+0"
#input_player2_l2_btn =
#input_player2_r2_btn =
#input_player2_l3_btn =
#input_player2_r3_btn =

input_enable_hotkey_btn = "6"
input_exit_emulator_btn = "7"

Attached is the full configuration file in case yours was blank like mine was. Good Luck
