I'd make sure the folder has a recognizable name (if I recall, the folder JNUSTool gives you has a name of tmp_somenumber, but you can rename it for WUP Installer). On the root of your sd card, you need to put the folder containing all the game's files on the root of your sd card. If you have this, install WUP Installer GX2 (that is, put it on your sd card I'd use the homebrew app store to install it, it's the simplest way).
h3 file extensions with the exception of title.tik, title.cert, and title.tmd. Ok, so you have got a common key and gotten a game.
