  • Okay guy i'm new on the forum and i'm little bit noob in electronics but i want to understand.

    I have issue with my PCB dragonrise (chinese aliexpress product you know...), here the first issue :

    • My RPI doesn't recognize button, when i push one of them there is a "not define" message. I've got 2 RPI, the 4 and the 3, at the begining i thought that was the fact the RPI 4 is to new fort the version of retropie, but i have the same problem on the RPI3...

    So because i'm tenacious, i've try one method that works but i want to understand why this is so hard to configure... I unplug all the buttons and configure each button one by one to plug and unplug each of them until it works... and it works !

    Someone have the explanation to this ?

    Thanks everyone for your reply !

    Looks like an encoder/wiring issue. If you test with jstest, outside of EmulationStation, are the buttons working ?

    I have a DragonRise Inc. USB Encoder and haven't had any issues mapping the buttons in Retropie 4.6 on a Raspberry Pi 4 4GB

    the config is here ...

    /opt/retropie/configs/all/retroarch/autoconfig/DragonRise Inc. Generic USB Joystick .cfg

    and inside the .cfg is my button mapping

    input_device = "DragonRise Inc. Generic USB Joystick "
    input_driver = "udev"
    input_enable_hotkey_btn = "6"
    input_l_btn = "0"
    input_load_state_btn = "0"
    input_up_btn = "10"
    input_left_btn = "11"
    input_state_slot_decrease_btn = "11"
    input_select_btn = "6"
    input_right_btn = "9"
    input_state_slot_increase_btn = "9"
    input_r_btn = "5"
    input_save_state_btn = "5"
    input_y_btn = "4"
    input_x_btn = "3"
    input_menu_toggle_btn = "3"
    input_down_btn = "8"
    input_start_btn = "7"
    input_exit_emulator_btn = "7"
    input_b_btn = "1"
    input_reset_btn = "1"
    input_a_btn = "2"
