Well I had some time to experiment and now my left analog stick is working.

It’s thanks to killer101 but I changed something.

input_player1_up_axis = “-1”
input_player1_down_axis = “+1”
input_player1_left_axis = “-0”
input_player1_right_axis = “+0”
input_analog_dpad_mode = “1”

The player1 did it.
I saw this because the rest of the config was like that.

This is the input config at the moment (/opt/retropie/configs/allretroarch.cfg)

input_enable_hotkey_btn = “8”
input_exit_emulator_btn = “9”
input_save_state_btn = “5”
input_load_state_btn = “4”
input_volume_up_axis = “-1”
input_volume_down_axis = “+1”
input_menu_toggle_btn = 3

input_player1_joypad_index = “0”
input_player1_b_btn = “2”
input_player1_y_btn = “3”
input_player1_select_btn = “8”
input_player1_start_btn = “9”
input_player1_up_btn = “h0up”
input_player1_down_btn = “h0down”
input_player1_left_btn = “h0left”
input_player1_right_btn = “h0right”
input_player1_a_btn = “1”
input_player1_x_btn = “0”
input_player1_l_btn = “4”

input_player1_l_x_minus_axis = “-0”
input_player1_l_y_plus_axis = “+1”
input_player1_l_y_minus_axis = “-1”
input_player1_r_x_plus_axis = “+2”
input_player1_r_x_minus_axis = “-2”
input_player1_r_y_plus_axis = “+3”
input_player1_r_y_minus_axis = “-3”

input_player1_up_axis = “-1”

input_analog_dpad_mode = “1”
