I have a bunch of wii's and wii u's. I only really use one and the rest are kept just in case they break. From what I understand it looks like the wii-u can't be kept powered off for long periods of time or it will break. My questions are as follows;
Is this also the case for the wii?
From what I understand its currently not possible to save a wii u console in the event of a nand failure if a nand backup is not present, does the wii also have this problem or can wii nands be swapped between consoles without issues?
I have two european and one japanese wii u's I plan on backing up all their nands. In the event of a nand failure will I still be able to use these consoles?
In the event of a nand failure of a wii would I still be able to use the console using some other nand from another console or a nand backup I made?
