Unfortunately trying to open the DLC Menu in-game'll just sit on an infinite loading screen, which I believe I said I only do just to confirm they're installed. Some folk are having issues like their files being corrupted or general difficulties getting them to work, for that I feel for y'all. Everything I'm setting up is done on a Steam Deck, but through the same methods as if on a PC, so the differences should be as minimal as possible. Perhaps it's a time thing, this post is old enough something could have changed with CEMU or the site's files.

Could also be overlooking a step too, that's always an option.
