So, I have no idea why my Wii isn't letting me install any more wads. I have tried various methods but none of them seemed to work. My last resort was a PimpMyWii perform test but that ended up in an "Exception (DS1) occurred" error. I am starting to fear that I have two diffferent IOSes conflicting with each other, but I have no idea what I'm doing. What I'm thinking of doing is basically doing a homebrew format to downgrade my Wii to 3.2U (I currently have a first gen model at 4.3U) and only install the things that are necessary, so I can completely start out fresh and continue to do what I was doing. The things I want to know are: 1. Is this possible? 2. Is it safe? 3. How would I go about doing it, or how would I solve the current problem I'm in right now?
