I formatted my system memory on my wii (4.1e cios14 preloader bootmii in boot2). I did this hoping that i could copy back saves i had backed up to sd card, i copied all ten pages worth. 1st issue was no saves would copy back. Second issue was, when i tired to restore to the nand backup i had done just prior to formatting, it tells me its from a different machine. Why is this, do your keys change???? and i stuck with a clean machine and no saves ??
