I got a problem with setting up shader presets. Specifically Mugwomp93’s 720x720 shaders and overlays for the RGcubeXX.
The problem i am having is that whenever i need to apply a shader preset, its not finding the .glslp files. and i am kinda stumped on what to do now. it looks like i am the only one with this problem, i cannot find any information to what i am doing wrong
a few things to note is that.
1: the consensus is that the video output needs to be gl, otherwise the glslp files wil not be found. i have checked this but the that option is already set to gl.
2: i can find glslp files when i browse the standard map (the one where you start in if you look for presets).
as information:
i am running 2601.0 Jacaranda (muOS)
i copied the files on a random place on my sd2 card (i dont think the files need to be in a specific folder right?)
i also cannot find glsl files (but i do find the “standard” preinstalled glsl files)
when i am trying to use the preset, i go into a game (wario land 1). i go to: Quick Menu\>Shaders\>Load Preset, and then try to find the specific file (GB\_Pocket.glslp in my case)
i hope people here know what to do, i love to play my games with shaders. but i can never seem to get the dmg right.
i have posted this to reddit as wel, i am hoping a muOS specific forum has more info, i hope you guys can help

That’s a retroarch bug/quirk.
It won’t read shader presets or shaders if the `/shaders` folder isn’t inside a retroarch folder.
You can create a `/retroarch/shaders` folder and move your shaders there, then it should work.
A more clean approach is creating archives to install the shaders and overlays in the internal retroarch directory.
Just get your `/shaders` folder(needs to be named `shaders`) and zip it to `shaders.zip`, the same for `/overlays` to a zip file named `overlays.zip`. Then rename the extension from `.zip` to `.muxzip`.
Then grab your your newly created muxzip archives, move them to the `ARCHIVE` folder, either on the root of sd1 or sd2, it does not matter which, and then in muOS go to applications\>archive manager and install both archives.
Now those shader presets and overlays will be available within the regular retroarch overlays and shaders folders.
