I need help right now. I was trying to boot up my old Wii and went directly to the Homebrew Channel through BootMii, but no apps are loaded, despite the apps folder being in my SD card. I tried using a different SD card, but still nothing. I tried going directly to the system menu, but all it gives me is a black screen, and I don't seem to find my nand backup anywhere. Is something wrong with the hardware, or is this an unfortunate case of bit rot in my nand? What can I do to get it working again?
