a custom retro CRT shader pack for Minecraft (Iris compatible). It shrinks the screen resolution to a pixelated 500x700 format, restricts the color palette for a 90s aesthetic. Made by UraniumTr, it leans cursed / fantasy and ships atmosphere and path tracing. Expect it to run comfortably from potato-tier hardware upward, on Minecraft 1.21 – 26.2 via Iris or OptiFine. Licensed MIT, so the download is mirrored right here on MineSpecs — no ads, no redirects.

How to install RetroPixel

1. 1Install a shader loader for Minecraft 1.21.9 – 26.2 — Iris (pairs with Sodium) or OptiFine. RetroPixel is a shaderpack, so it needs a loader to run.
2. 2Download the RetroPixel .zip from the button above — keep it zipped. It is mirrored on MineSpecs, so there is no ad-gate or redirect.
3. 3Drop the .zip into your .minecraft/shaderpacks folder (%appdata%\.minecraft\shaderpacks on Windows, ~/Library/Application Support/minecraft/shaderpacks on macOS).
4. 4Launch the game, open Options → Video Settings → Shaders, and select RetroPixel.
