I copied this post from reddit, realizing this could be a pretendo instead of a cemu problem:
I copied all the files from my Wii U and was able to play mario kart 8. However, when i start splatoon i dont see any Miiverse (juxta) posts and when entering the lobby, it request me to connect to the internet: “To participate in online battles, you will need to connect to the internet and receive the latest News data.”. If i press Receive i get kicked back to the plaza, if i press Don’t Receive i also get kicked back to the plaza. Then going to the miiverse letter box and press Miiverse post, it loads shortly and just aborts and the dialogue closes. I dont get any error messages whatsoever (do i have to enable them somewhere?)
