This filter takes an input and uses it to replicate the result of using a gameboy camera to take a picture. There are 14 palettes to choose from, and options for levels and high pass.
Special thanks to Bruno Alfonseca - https://www.artstation.com/bruno for the dither filter on Substance Share. Doing a dither manually would take me too much time, and his work is very solid.
Also thanks to the youtube channel "Wulff Den" For the inspiration.
I will follow this up with a actual Gameboy substance once i have the time ;)
