Hi, total noob on Wii U system and what I want is to be able to play backups or downloaded games on an external hard drive. The same way that is possible to do on the Wii. What would the necessary steps to be done? What method is the easiest and most safe? What tools to use in order to extract the files? What tools to add the image (wux?) on the harddrive and then be able to play them? Sorry for the noob questions but I don't want to brick my kids Wii U. They would never forgive me for doing that. Thanks.
