I made two Overlays one for GB and one for GBC, cause I can’t find some with a good looking frame and emulated screen size. They can used up to 1080P. Feel free to use or edit!
Here is V2 of my GB Overlay. It’s a more realistic verion I think. I use it with this shader: https://github.com/ghogan42/common-shaders/blob/zfast_shaders/gameboy.glslp
I like these! I like the streamlined artistic look of them.
