Is there a Game Boy Advance emulator for Retropie that supports screen rotation?

    That's it. That's the question.

    Raspberry Pi 3b and 8GB Raspberry Pi 4, both running Retropie 4.7.1 installed from scratch using Raspberry Pi Imager, with wired keyboard, wireless mouse and double arcade joystick attached.

      @jimmyfromthebay any libretro core run via retroarch supports screen rotation. adjust it via a core/game override.

      # Forces a certain rotation of the video.
      # The rotation is added to rotations which the libretro core sets (see video_allow_rotate).
      # The angle is <value> * 90 degrees counter-clockwise.
      # video_rotation = 0

        @dankcushions i remember some video drivers have/had limitations about that though, like the one directly using the rpi low-level stuff (dispmanx ?)

          @barbudreadmon ya, but retropie on pi defaults to the gl driver which does indeed permit it.

            @dankcushions Yeah, that's what I thought, but I couldn't find the options anywhere. I forgot how well-hidden the "Show Advanced Options" menu is...
