I have a couple of games that are advising they have updates, Call of Duty Black Ops II won't even start without the update. These games do not appear in WiiU USB Helper lists. Is there an app that will allow us to download the update on PC, to install via WUP Installer in WiiU? Or even an app that runs on WiiU that allows us to update games without updating our systems to 5.5.2? I am not currently running custom firmware, and I am pretty sure there is a simple way to do this. *edit* Thanks to those that took the time to read my question. NNU Patcher seems to be the answer. Once run via homebrew launcher, check you can connect to eShop, then simply launch game that requires update. I'm currently investigating why a couple of my games give server errors, while the others update fine.
