Your favorite retro games look wrong on modern screens, and only RetroArch's shader presets fix that

Retro games were designed for CRT displays, and playing them on modern screens strips away the visual quirks — scanlines, phosphor masks, color bleed — that made them look cohesive. RetroArch's shader presets simulate these CRT characteristics, restoring the intended look. Getting started is straightforward: enable Video Shaders in the Quick Menu, load a preset from the shaders_slang directory, and pick a preset suited to your system (e.g., CRT_Royale for SNES/PS1, LCD-style for Game Boy). Lighter 'lite' or 'Fast' variants are available for modest GPUs.
