Map any key to a button



  • Hi!
    I want to map any key to a button. It's possible?
    I know with retroarch you can map specific actions, but I can't found how to map any key.
    For example, in Livingstone Supongo for Amstrad to change weapon is the key 1,2,3 and 4.
    Can I map to a button?
    I have Xin Mo controller with joystick and buttons and a 8bitdo gamepad

    Thanks!

    Emulationstation is just the front-end (launcher), the emulator depends on the game you're starting. Anyway, when in-game, press Select + X and this should bring up the RetroArch GUI, which has a controls/input section. Use that section to re-map your button to your liking and then save is as a Game or Core remap (see here). This should work for most RetroArch based emulators, (such as lr-caprice for Amstrad), individual emulators may have their own control configuration menu or configuration file.



  • Thanks for response.
    I use lr-caprice32 for Amstrad. With Retroarch I only can map buttons A,B,X,Y. I play Livingstone Supongo with keyboard, with key numbers 1,2,3 and 4 I select weapon. How Can I map this keys of keyboard to a button?
    Thanks



  • Hello, finally I found the solution.
    In retroarch select Amstrad Keyboard for device type
    alt text
    Now you can map keys to a button, In my case, start for key space, button X to keyboard 1, button Y to Keyboard 3.....
    In retroarch:
    alt text
    Auto: 4 -> Keyboard 2
    Auto: 7 -> Keyboard Space
    Auto: 3 -> Keyboard 1
    Auto: 5 -> Keyboard 3
    Auto: 2 -> Keyboard 4

    The file of map with ASCII code of the key and 259 of type of Amstrad Keyboard:
    /opt/retropie/configs/amstradcpc/cap32/livingstone.rmp

    input_player1_key_y = "50"
    input_player1_key_start = "32"
    input_player1_key_x = "49"
    input_player1_key_l = "51"
    input_player1_key_r = "52"
    input_libretro_device_p1 = "259"

    Thank you!!
