    is there any way to change the fire button in Atari ST (Hatari) emulator? It is mapped to the select button in my ps3 controller (very hard to play..). I’ve tried to edit the configs with F12 but there is no option to map the joystick.

    Any ideas?

    To anyone with this problem I’ve figure out the solution based on this post:

    We have to recomplie the emulator.

    Hatari emulator is waiting for a code 0 to fire button. That is the select button in the PS3 controller as retropie configures it. After a long research I’ve finally found where the Hatari hardcodes the fire button event.

    First download source files for hatari:

    cd RetroPie-Setup
    sudo ./ hatari sources

    then go to

    sudo nano /home/pi/RetroPie-Setup/tmp/build/hatari/src/joy.c

    All you have to do is edit the lines code where this event take place. Lines 206 and 208

    pJoyReading->Buttons = SDL_JoystickGetButton(sdlJoystick[nSdlJoyID], 0);


    if (SDL_JoystickGetButton(sdlJoystick[nSdlJoyID], 1))

    replace to

    pJoyReading->Buttons = SDL_JoystickGetButton(sdlJoystick[nSdlJoyID], 14);
    if (SDL_JoystickGetButton(sdlJoystick[nSdlJoyID], 13))

    X to fire and O to space fire (some games needs this). The other buttons are []=15 and triangle=12

    You may want to add this line to exit the emulator without the keyboard with the PS3 select button:

    if (SDL_JoystickGetButton(sdlJoystick[nSdlJoyID], 0))

    Then build

    sudo ./ hatari build

    and finally

    cd /home/pi/RetroPie-Setup/tmp/build/hatari
    sudo make install

    Enjoy playing Atari ST!!
