Id added too many and itll suck going one by one to remove them, maybe an app that wipes it all together? Also maybe clear the users played with list too?
Wouldn't be as trivial as it could since they are (also) stored server side; maybe there's a developer app for that already made but I don't remember if that's actually the case (as it is on the 3DS)
Well, that would be some challenge, but I'd think upon launch it would take control of the wii u, and would obviously count how many friends and manually unfriend the users. Not sure on it though.
I have a question about Medicat if anyone can answer.. My windows install is corrupt and wont boot. Does Medicat allow you to run DISM online or do an inlace upgrade? Trying to do some sort of repair install or recovery without a fresh installation
