This is a pack of shaders for old-school video game emulators. Copyrights are held by the respective authors.

*NOTE*: This is not a standalone game or emulator. You will not even get an icon in the Android launcher after it is installed. Instead it works as an add-on to compatible emulators.

Most of the shaders are converted from the work of their original authors, in order to make them work on GLES 2.0. Shader files are based on the higan XML shader format version 1.0, with slight changes and enhancements. The format itself is quite straight-forward.

Following shaders are currently included:
• hq2x/hq4x
• Scanlines
• Motion blur
• Grayscale

Source code is available at https://code.google.com/p/emulator-shaders/
Welcome contributing new shaders to the project! In the meantime, we would also like to see more compatible emulators in the future!
