OK, I cannot seem to apply shaders to any of the emulators that come included. I navigate to the ‘shader’ folder but nothing is selectable. I remember applying SUPER EAGLE to SNES and GENESIS and it looked great - is it the same as EAGLE in the shader folder?
You can’t select individual Cg shaders with ‘Load Preset’. Load Preset is for exactly that - Cg shader presets.
Instead, you should set a shader per pass. Set shader passes from 0 to 1 - and select a shader per pass.
