A small pack of shaders to replicate that old PS1 look in Godot 4.0.
They may also work on Godot 3.x, but they haven't been tested. Proceed with caution!
Warning
Gouraud shading is currently broken in Godot 4.x, so use 3.x or wait until 4.4 releases if you need it.
Dithering and lit/unlit shaders are based on work by Mighty Duke, which was licensed under the CC0 license.
Dithering shader is based on: https://godotshaders.com/shader/ps1-post-processing/
Lit and unlit shaders are based on: https://godotshaders.com/shader/ps1-shader/
Thanks to the HauntedPS1 community for inspiration and help with the Fade shader quantization.
