So, I put the Smash Bros. Brawl hack on my Wii U so I could play homebrew on the Wii half of the system. It worked pretty well for a while, but recently I went back to the system and discovered that it's gotten a lot more temperamental. Stack/DSI errors are frequent, locking up the machine and forcing me to unplug it to regain control. From what I can tell, the Wii U works perfectly fine, and I haven't had any problems with official Wii apps and discs (although it's been a while since I've used those... maybe I'd better check and make sure). It's just the Homebrew Channel and its apps that have been giving me fits. What would you suggest as a fix? Should I run the Smash Bros. hack on the system again? What other options are available to me? I appreciate any help you can provide!
