Does anybody know of a way to create a shader which pixelates and/or limits colours of the screen?
The colour limiting could be either inputting a number of colours or just making a table consisting of all possible colours. There would also need to be a way to get the closest colour to the pixel's colour I would imagine. Anyway, has anyone made this / knows how I could make it?

Or the SNES effect when games would transition from one setting to another like in Mario World when you change from the castle or ghost house intro to the level itself, or Zelda LTTP when you open the map.
But I think the OP means taking the screen image and using a Photoshop-like color dither effect like when you convert an image to a GIF which has a 256 color limit so it has to dither.
I'd say it's easier just to dither the images from the start instead of trying to fake it because it's not going to look right without a lot of work.
Then again, there are times you still need to dither I guess.
