Just yesterday I installed the Homebrew Channel using smash stack on the virtual Wii on my Wii U. I installed cIOS on 249-51 and successfully used the USB Loader. I also have a backup of the NAND on my desktop. However, just suddenly and recently, the menu is incredibly choppy, and loading any app results in the crash. Even waiting on the initial menu long enough triggers it. What options do I have?
