I have saved a shader preset as the default for the mame core that I’m using but every time I load up the same game it never applies it for me and I have to manually go in and apply the shader again. I double checked to see if the preset is saved and its in my Retroarch > config > MAME > MAME.slangp so I know the file is there, but why doesn’t retroarch automatically load it?
I’m on Windows 10 and using Retroarch v1.20.0 and MAME 0.273 core.
