Bundled slang shader presets
============================

These RetroArch slang shader presets are included with the Windows version for use with
Options > Graphics > Slang Shader (run through librashader.dll). They are unmodified copies
of files from the libretro slang-shaders collection:

    https://github.com/libretro/slang-shaders   (master branch, fetched 2026-11-04)

The folder layout is the collection's own, so each preset finds its files. Only the files the
presets below use are included.

Each shader file keeps its original copyright and licence notice. The GNU General Public
License version 2 is in LICENSE-GPL-2.0.txt; the MIT notices are in the files themselves.
The shaders are separate files the program loads at run time; they are not part of the
program's own code. The full source of every shader is these files.

Some presets were made for a 4:3 picture and can stretch or frame oddly in widescreen.
