    I built a cocktail table and I'm thinking I'd like to have a module I can put on top using a mirror to redirect the screen image, but of course that means things will be flipped... Is there any way I can mirror the screen image?

      Look in nano /boot/config.txt

      display_rotate=#
      

      where # does the following:
      0 = no rotation
      1 = rotate 90 degrees clockwise
      2 = rotate 180 degrees clockwise
      3 = rotate 270 degrees clockwise
      0x10000 = horizontal flip
      0x20000 = vertical flip
      0x30000 = both horizontal & vertical flip

        Please note that rotating/flipping etc can affect graphics performance.

              Hello everyone! Can you show how your mirroring images looks like on you cocktail table? Can you use it with MAME games at all?
