Placing them in root does nothing. They are there, but the system doesn't give a flying f***. DevMenu or blue...somethingsomething, I forget the name. Installs that .cia to the system, so it acts just like an eshop downloaded title.Quick question.. what's the purpose of dev menu? I heard it has something to do with .cia files, but I thought you just placed .cia files on the (root) of the SD card
