1. A "base" d3dx.ini, that won't need to be updated. 2. ShaderOverrides.ini which can be updated as needed. (put it in your Mods folder or a subdirectory in Mods) 3.  "d3dxini_shaderoverrides.zip" contains the two above and can be extracted into your main game directory - and you're good to go. 4. A html/javascript app for modders who do shader hunting, aids in organizing/searching for updating shaderoverrides and generating the "ShaderOverrides-YYYY-MM-DD.ini" file
