I’m looking for a way to invert colors in Retroarch. I think it may be possible with Color Mangler, but I would need some help figuring out how to use it. Is there any shader that can invert colors?
I’m running Retroarch in an arcade cabinet through a CRT monitor with negative video. There is a switch on the chassis to invert the video, but I am tired of switching it back every time I put an original PCB back in.
As I read that back it sounds crazy, but the switch is really hard to get at… I have to use a stick!
Thanks either way.
