I think it would be good to format wi u and start from scratch.
If i do so, whill games on my hdd still work? Will the saves still be useable?
Is it possible to back up my mii's, or do i have to recreate them? Do i have to uninstall cbhc first or is it save to directly format wii?
To keep things simple: is there a TuT on formating the wii u and get everithing back onto the clean wii u?
Or is there a tidy up tool?
Because i have also problems with installing stuff via wup installer. So i think my wii u is "dirty" and needs to ve cleaned
