RetroX Mini Guides - Shaders Here is another of my mini guides for RetroX. The aim is to create small bite size videos showing how to perform certain tasks and highlight certain features. The guide shows how to test and set shaders. Shaders are efficient graphics filters that can greatly improve the rendering of old games. They can also be used to replicate the look and feel of old CRT monitors. Notes/Links: RetroX Website: http://retrox.tv
