Some shaders for RetroArch

Installation

------------

Copy the content of the `shaders` directory to the `shaders` (or any sub-folder) directory of your RetroArch installation.

Description

------------

**nop.cgp**

No-operation shader, just passes content as it is.

**cmyk.cgp**

Renders to CMYK color space using an AGFA SWOP Standard color profile.

It gives that printed-on-paper look'n'feel, barely noticeable on some games on some others it just rocks. Dark/futurist themed games such as Wipeout or Twisted Metal are good candidates. While on overall colors are washed out, blue tends to be more vivid and give a definitely different aspect, currently my favorite one :D

Note: your GPU must handle 4096*4096 textures !

**scanlineFlicker.cgp**

This shader does flickering scanlines like in a CRT.

By default a scanline height equals the height of one scanline at the game resolution level, if you'd like to have screen-level scanline heights, refer to the documentation inside it.

**grayAverage.cgp**

This gray shader uses the poor man's gray algorithm, channels are added and divided by 3.

**grayBT601.cgp**

This gray shader uses the same transformation matrix used in SDTV.

**grayBT709.cgp**

This gray shader uses the same transformation matrix used in HDTV.

**grayBT709Negative.cgp**

Same as *grayBT709* except that black is white and vice-versa, like the alien vision in AvP.

**technicolor1.cgp**

Technicolor shader, a color process used in early film shootings which consisted of filming using multiples films and merging them to color the motion.

See http://en.wikipedia.org/wiki/Technicolor for more.

This version uses an additive blend of red and blue channels.

**technicolor2.cgp**

Technicolor shader, this version uses a multiplicative blend of red and blue channels.

**technicolor3.cgp**

Technicolor shader, this version does matting between all channels.

**technicolor3-w.cgp**

Technicolor shader, this version uses cyan, magenta, yellow and red/orange filters.

Notes

-----

If you'd like to tweak the shaders, you will find explanations of variables of interest in the shaders themselves.
