Most shaders don't seem to work? [Mednafen PSX (HW and not)]

Hey everyone,

I can’t seem to get any shaders aside from AA shaders to work with either the HW or software Mednafen PSX cores. I’ve tried both 64-bit and 32-bit RetroArch.

As I understand it, the cg and glsl shaders are meant for any renderer aside from vulkan. And slang shaders are meant vulkan. For example, I have the RetroArch driver set to vulkan. I then load a game with Mednafen PSX HW core. The renderer for the core is set to vulkan. From the RetroArch menu, I then attempt to apply any single pass slang shader and I see no difference in the game. However, the AA shaders do work (i.e. FXAA).

Am I missing something? All of these shaders work just fine in other emulators.

Many of the shaders are dependent on low-res images to have a noticeable effect. Are you cranking up the internal resolution? If so, a lot of them will have either no effect or a very subtle effect. For example, a lot of the CRT shaders will just tint the picture slightly yellow or whatever.

Thanks, that was issue!
