Dreamcast and PS3 controllers not working



  • Good Evening Gamers,

    I am having issues using my PS3 controllers with Dreamcast. These controllers work with all of my other systems but Dreamcast. I tried manually mapping and I still get nothing when I hit start to play a game. I am working with with Retropie 4.5.1 on a Raspberry pi 3 B+. Below you will find my mapping.

    Manual Configuration
    input_device = "MY-POWER CO.,LTD. 2In1 USB Joystick"
    input_driver = "udev"
    input_r_y_plus_axis = "+3"
    input_r_x_minus_axis = "-2"
    input_l_btn = "4"
    input_load_state_btn = "4"
    input_start_btn = "9"
    input_exit_emulator_btn = "9"
    input_r_y_minus_axis = "-3"
    input_down_btn = "h0down"
    input_l_x_plus_axis = "+0"
    input_r_btn = "5"
    input_save_state_btn = "5"
    input_right_btn = "h0right"
    input_state_slot_increase_btn = "h0right"
    input_select_btn = "8"
    input_left_btn = "h0left"
    input_state_slot_decrease_btn = "h0left"
    input_l2_btn = "6"
    input_l3_btn = "10"
    input_l_y_minus_axis = "-1"
    input_up_btn = "h0up"
    input_a_btn = "1"
    input_b_btn = "2"
    input_reset_btn = "2"
    input_enable_hotkey_btn = "8"
    input_l_y_plus_axis = "+1"
    input_r2_btn = "7"
    input_r3_btn = "11"
    input_x_btn = "0"
    input_menu_toggle_btn = "0"
    input_l_x_minus_axis = "-0"
    input_y_btn = "3"
    input_r_x_plus_axis = "+2"
