The only reason I'm actually interested to participate in this GBjam for once is that I wrote some retro shaders for Unity a couple months back, and one in particular lets me define a palette of colors and it will map the screen's colors to this palette. I figured this could be of interest to other participants as well so I decided to share them!
This repository has 3 image effects:
- Fixed palette
- Graded palette (may not be ideal for this competition but it lets you define gradients)
- Dithering (With any arbitrary dither pattern image)
- Resolution downsampling (I made it default to the GB screen resolution, so you don't have to mess with the parameters once you add it to your camera!)
- Color quantization (posterization, may not be too helpful for this jam)
Example you can obtain with this
You can open the prepackaged scene in unity to see how it was done. Also, I suggest creating an aspect ratio like this so that it always display the true downsampled resolution
