u/Arongo_Natolk

Just yesterday I was playing Punch Out, all good. Then i took My Wii U to a friends house to play there and when i'm done setting everything up, the screen just loops looking like this (I took the image from another post, but basically it's the same that's happening to me). I tried to insert and reinsert the SD card as it helped in the past when similar problems happened, but didn't work. I tried to put some "backup" files I made back then of the SD card, and trying again... Nothing.

I got tiramisu and aroma installed. I'd appreciate and help, even if I have to uninstall everything and reinstall.
