Diffrent controller map for select emulation?



  • I have been converting classic controllers to USB using a nice little circuit. Everything was going great until I configured my SNES controller.
    I found out the hard way that the SNES and Sega setting use the same controller ID.
    Obviously I can't change the controller ID, however is it possible to set the Sega systems to load up a different controller map? This would be ideal just because of how annoying it is to re-map the controller if I switch between a Sega game and then a Nintendo game.

    FYI, I will be out for a while, but I will be working on this later tonight.



  • I got it!
    Person on Reddit had the solution.

    The original solution was provided by the reddit user delusion666. I modified it because he was using RetroPie 3 and I am running the latest version as of a week ago.

    I configured my controller in EmulationStation. It created a controller config file in:

    /opt/retropie/configs/all/retroarch-joypads/

    In my case, it was raphnet.net (S)NESAtari_USB.cfg

    Next, I created retroarch-joypads dir in the MegaDrive configs dir and copied the raphnet.net (S)NESAtari_USB.cfg to there:

    /opt/retropie/configs/megadrive/retroarch-joypads/raphnet.net (S)NESAtari_USB.cfg

    Finally, for retroarch to see the file, you need to add or change this line in /opt/retropie/configs/megadrive/retroarch.cfg :

    joypad_autoconfig_dir = "/opt/retropie/configs/megadrive/retroarch-joypads/"

    I commented out the original line and then added a new line above it for backup/troubleshooting purposes so my file like like this at the line :

    joypad_autoconfig_dir = "/opt/retropie/configs/megadrive/retroarch-joypads/"
    # Original line - joypad_autoconfig_dir = "/opt/retropie/configs/all/retroarch-joypads/"

    I had to do that for the MegaDrive, Sega 32X, and Sega CD. I don't think you need to make the file three times, probaly just need to make sure the path is correct. However the map file is real small so I made one for each system.

    Finally, I re-configured the SNES controller so if I load up anything with the SNES controller, it's mapped out correctly.
    Now if I load up either the MegaDrive, 32X, or Sega CD RetroArch uses the controller map for the Sega controller.
    I was lucky as the buttons for the D-Pad, A, and B didn't change with the SNES mapping so the Sega controller works the exact same in EmulationStation.

    Good luck. If you still need help, just ask and I will try to assist.
