as tittle say, also they suggest me to get access to this 3ds and do a system transfer back, but this even impossible ( afaik you cant transfer from n3ds to o3ds). basically dont need this nnid anymore ( purpose was just exidia game on this nnid in good ol' days). but still : does they have right to do so? ( yeah i know about nin politics : fuck you, we got eula, you got nothing) but simple nnid untie? wtf?
