      Hello All,

      I was trying something new and ran into an interesting issue. I am unable to find a way to invert my video signal to my LCD so that when added to an arcade cabinet that uses a mirror it displays correctly. To be clear I can use the rotate function to turn the display, but the video NEEDs to be inverted so that the words are displayed backwards when you look at the screen normally and then when looking at it in the mirror it is correct. Any thoughts are appreciated!

        @red732 a shader could do this. eg: https://github.com/libretro/glsl-shaders/blob/master/misc/flip-horizontal.glsl

        any arcade game that was available in such a cabinet probably has a system option to run it in a flipped mode - maybe in the service menu or dip switches. eg https://retropie.org.uk/docs/lr-mame2003/#service-menu
