retroarch arcade button 'A' conflict with Emulatorstation config? - have tried everything



  • Team - please help if you can. I am so close to finishing off my arcade machine.
    I have read all the forums. Am editing the config files externally in Notepad++

    My setup -

    • 2 player arcade machine. 6 buttons each. Ipac2 keyboard encoder.
    • all buttons and joystick controls tested and working fine.
    • emulatorstation binds all working fine. can navigate around no issues.

    My issue

    • launching into a MAME game and all buttons seem to work fine, except the 'input_player1_a' which is mapped to "ctrl" (my SW1 button).
    • SW1 button works fine in emulatorstation and is mapped to 'a'.
    • when loading a MAME game, as mentioned i cant seem to use the first arcade button for player 1. Player 2 seems fine though and plays well.
    • I confirmed using an external USB keyboard that i cant press L-ctrl to see if that works.

    I understand that there is 2 key retroarch config places -

    • \CONFIG\all\retroarch.cfg
    • \configs\mame-libretro\retroarch.cfg

    i made sure both show the same binds for player 1 and 2, and i have made all the other binds null. The only thing i can think of is emulator station config is conflicting with the retroarch.cfg files.

    please if anyone can help as i am out of ideas, but so close to finishing this project! I provide copies of my setup config below...
