Non-existent Wii Menu

[leolam]

Sounds like your NAND is messed up. Assuming you're using Windows (which is likely true), your NAND root is at %userprofile%\My Documents\Dolphin Emulator\Wii. I suggest backing up your saves and deleting this (to keep it simple); alternatively, look up the correct ID for the system menu and delete only what you need to.
