Fixed shader links
===CRT-Geom===
{{Main|CRT Geom}}
*[https://github.com/libretro/common-shaders/blob/master/crt/shaders/crt-geom.cg crt-geom.cg]*[https://github.com/libretro/common-shaders/blob/master/crt/shaders/crt-cgwg-fast.cg crt-cgwg-fast.-cg]
Simulates an aperture grille display (with the dot mask enabled). Very versatile and modifiable. One of the first popular CRT shaders. Visit the main article for more details.
===CRT-Calagari===
*[https://github.com/libretro/common-shaders/blob/master/crt/shaders/crt-caligari.cg crt-calagari.cg]
An older CRT shader similar to CRT-Geom but uses different methods to achieve its effects.
===CRT-Easymode===
*[https://github.com/libretro/common-shaders/blob/master/crt/shaders/crt-easymode.cg crt-easymode.cg]*[https://github.com/libretro/common-shaders/tree/master/crt/shaders/crt-easymode-halation crt-easymode-halation]
A flat CRT shader whose settings are easier to understand. Similar to CRT-Geom in its effects.
===CRT-Hyllian===
*[https://github.com/libretro/common-shaders/blob/master/crt/shaders/crt-hyllian.cg crt-hyllian.cg]*[https://github.com/libretro/common-shaders/blob/master/crt/shaders/crt-hyllian-fast.cg crt-hyllian-fast.cg]

===CRT-Lottes===
*[https://github.com/libretro/common-shaders/blob/master/crt/shaders/crt-lottes.cg crt-lottes.cg]*[https://github.com/libretro/common-shaders/blob/master/crt/shaders/crt-lottes-halation.cg crt-lottes-halation.cg]
A newer CRT shader that uses a horizontal shadow mask pattern with blooming. The horizontal pattern works quite well at current resolutions, though it isn't entirely accurate to a true vertical slot mask pattern.

*[https://github.com/libretro/common-shaders/tree/master/crt/shaders/crt-royale CRT-Royale]
A highly advanced multi-pass CRT shader that simulates almost every aspect of the CRT screen. There are tons of parameters to configure, such as phosphor type (aperture grille, slot mask, and EDP shadow mask) and size (i.e. dot pitch), convergence offests, scanline blooming and many others. Higher resolution is better for this shader, especially with EDP shadow mask phosphor layout and with smaller phosphor dot pitch values. This shader is really complicated compared to most other CRT shaders, reading the README and the documentation in the user-settings.h is a must.
