Options
Number of quantized color steps per channel. Each color channel (red, green, blue) is rounded to the nearest multiple of
1 / retroLevels, producing a palette-limited look. Lower values produce a more extreme retro appearance; higher values approach full color. Suggested range: 4–63.Pixel grid scale in screen pixels. The shader samples colortex0 at a lower effective resolution by snapping UV coordinates to a grid of this size. Higher values produce larger, chunkier pixels. Set to
1 to disable pixelation entirely. Suggested range: 1–16.Darkness of alternating scanlines. Every other row of pixels is multiplied by
1 - retroScanStrength, mimicking the horizontal scan lines of a CRT display. Set to 0.0 to disable scanlines completely. Range: 0.0–1.0.Darkness of the edge vignette. Controls how strongly the corners and edges of the screen are dimmed. The vignette fall-off shape is fixed (inner radius 0.35, outer radius 0.90). Set to
0.0 to disable the vignette entirely. Range: 0.0–1.0.Scale of the Bayer 4×4 dither offset applied before color quantization. Higher values spread the dither pattern more aggressively, reducing color banding at the cost of a noisier image. Set to
0.0 to disable dithering. Range: 0.0–2.0.retroVignetteInner (0.35) and retroVignetteOuter (0.90) define the shape of the vignette fall-off. These values are fixed in the shader source and are not exposed as user-adjustable options.Presets
The following presets demonstrate how to combine options for specific retro aesthetics. Enter these values manually in the Shader Pack Settings panel.Classic Game Boy
