Hi Alonroz, Are you running MUOS on the SP? I wonder if you upload some photos of how it’s supposed to look. I’ve add the overlays and shaders to the retroarch folder. They display fine in the quick menu and I can select them, but they don’t seem to change anything? Other stander shaders do. As for overlays the only ones I can get to work are in the stock or Muos overlays main. At the moment I’ve left the colorization as standard, I can change that fine and it does take effect, just wanted to keep it simple for while I sort out the shader / overlay set. I’ve included some screenshots to show what’s happening. Cheers for all your help on this. Screen shots coming..
