Simple shader, the goal is to imitate the look of the PSX Games.
Keep in mind, viewing experience might be different on different resolutions, due to scale lines, you can see weird lines appear on images...
For example my Display is 3440x1440, so its 1440p 21:9, and this is how I tested it.
For best images I recommend going into gallery of this project!
