When looking at games in the Wii U USB Loader application, some games will allow you install an "Update," and I'm not really sure what this is. Is it an update tool for the game for when a new update comes up? Is it required to download the "Update" if I plan on putting the game into my Wii U? I hope someone can clear this up for me because I'm genuinely curious. Thanks! (sorry for the noob questions).
