I could not find a straight answer to this so posting for clarity please. I have the EU disc and want to play but read there is a game update on the disk and/or some internet update as well. Can I go online and just update the game with the released patch or will my wii u try and do a system update as well - which i want to avoid. Either way is it safe for backup loaders and stuff do they all work ok after the zelda update?
