  • I'm starting to wrap my head a bit around configuring my ipac2 with retropie. I managed to get it working for retroarchgui by downloading retroarch.cfg in the configs>all folder, editing it in notepadd++ then uploading it back to the raspberry pi. I have the buttons mapped for emulationstation by just using the options menu.

    I then tried to do the same download/upload editing cfg for snes but it seems to not take when testing a rom.

    Am I going about this the wrong way?

    Maybe. If you already configured your gamepads globally, why do you want to re-configure again for snes ? The file you edited is already active for all RetroArch emulators (cores).
    If you want to have different mapping for each system, in RetroArch, use the RGUI and create a core re-mapping specifically for that system - see here for more details.

  • Have been following this guide mostly so that's why I was going farther than mapping the buttons globally.

    So what I've done since posting is going into the retroarch menu from emulationstation (the green menu) and noticed that none of the player 2 buttons had been mapped. So I mapped them and then double checked my player 1 mapping to make sure I had it like I wanted it.

    I then go back to emulationstation and try an SNES rom (Street Fighter 2 alpha) and none of the buttons work. Can't even exit the game back to emulationstation. Try an FBA rom and same thing.

    Edit: Was messing around with the green retroarch settings again and loaded a game from there and controls worked. So starting a game from emulationstation doesn't work but loading it from retroarch does?

    @GBH You probably overwritten the .cfg for the system and the global mappings don't apply. Did you enable 'Save Configuration on Exit' ?
    When starting RetroArch from Emulationstation, the system's configuration is loaded from /opt/retropie/configs/<system>/retroarch.cfg. Usually this file is almost empty and includes the global config /opt/retropie/configs/all/retroarch.cfg.

    I didn't know/understand that there was mapping "above" global. I thought it went global > emulator > rom.

    "Save configuration on Exit" is off.

    Is there a somewhat easy way to start from square one with the mapping? Or do you have a suggestion of how to tackle the pickle I've gotten myself in?

    No, it's the other way around - see If you have a rom.cfg it trumps the system's .cfg and any system's .cfg trumps the global .cfg. Specific game/system setting apply before the global ones.

    You can easily reset the config for a system by looking in the system, configuration folder (/opt/retropie/configs/<system>) and renaming the retroarch.cfg file, then re-installing the emulator for the system. This should re-create the default config file.

  • I know it's been a few days but finally found some time again.

    I'm looking at my /opt/retropie/configs/snes/retroarch.cfg

    input_player1_b = "shift"
    input_player1_b_btn = "nul"
    input_player1_b_axis = "nul"
    input_player1_y = "ctrl"
    input_player1_y_btn = "nul"
    input_player1_y_axis = "nul"
    input_player1_select = "5"
    input_player1_select_btn = "nul"
    input_player1_select_axis = "nul"
    input_player1_start = "1"
    input_player1_start_btn = "nul"
    input_player1_start_axis = "nul"
    input_player1_up = "up"
    input_player1_up_btn = "nul"
    input_player1_up_axis = "nul"
    input_player1_down = "down"
    input_player1_down_btn = "nul"
    input_player1_down_axis = "nul"
    input_player1_left = "left"
    input_player1_left_btn = "nul"
    input_player1_left_axis = "nul"
    input_player1_right = "right"
    input_player1_right_btn = "nul"
    input_player1_right_axis = "nul"
    input_player1_a = "z"
    input_player1_a_btn = "nul"
    input_player1_a_axis = "nul"
    input_player1_x = "alt"
    input_player1_x_btn = "nul"
    input_player1_x_axis = "nul"
    input_player1_l = "space"
    input_player1_l_btn = "nul"
    input_player1_l_axis = "nul"
    input_player1_r = "x"
    input_player1_r_btn = "nul"
    input_player1_r_axis = "nul"

    This is what's exactly in the file for the button mapping for P1 and when I go into Super Street Fighter alpha 2 it doesn't work. Made a rom specific cfg too and still doesnt work. Now here's the super weird part ... tried Star Fox 2 and controls seemed to work fine. Tried Super Star Wars and same problem as SFA2.

    Edit: Also how do I go about reinstalling an emulator?
