Does any know of a supported way to save per-game shader presets? I get an error in Retroarch when I try to do it via the Retroarch menu. I receive "Error saving shader preset:". I'm assuming the shader area is read-only, but I would like to change my shaders by game, especialiy remove shaders from Vector games, and set my favorite zfast standard and vertical shaders for my arcade games / per game.
Thanks for the guidance!
