"This project simulates the Game Boy Camera, an old product from 1998, by capturing a photo from your webcam and turning it into a 128x112 4-color monochrome image, with optional Bayer dithering - the same as the real thing uses. Most of the instructions are in the project. Enjoy! Also, yes, the image in the thumbnail is an actual photo, of my Game Boy and Camera, taken with this project. Talk about meta, eh?" (hmnwilson)
There is a unique selection of pallets and colors.
