Okay, so I've downloaded the latest version, have the iso, I open the solo launcher, set iso path, and it doesn't load the custom textures. Looks unmodified with no 4k banner popping up at the title screen. Using all default settings from the download.
If I dump the textures to regular dolphin the show up and it get the 4k banner. However, I don't seem to get all the post processing benefits. Am I missing something simple?
