I just purchased a Wii system. Hopefully I can transfer my backup NAND to this new one and it will work. Does anybody know if I will lose anything out of this (purchased games, friend codes saves, etc.)?
You can't reflash your NAND to a new Wii unfortunately, since the keys won't match. But you can use ShowMiiNand/ShowMiiWads to extract titles you want to keep from your old NAND and install them on the new Wii.
My NAND is not showing up on ShowMiiNand program. I extracted my NAND with folders such as import, meta, shared1, sys, ticket, title, etc.. Now how would I go about putting the titles on the Wii (making them into wads)? I have games, saves, miis on the nand. Is there any way that I can get those components on the Wii?
