Install the update through Nuspli

If you have a disk, dump it on a HDD or NAND. Then You Install Wii U USB Helper. And download the update then install it whit WUP INSTALLER. Note: You will need a special website to use USB HELPER. Which i can't tell you because of piracy. You will find it by asking AI

BUT DON'T PIRATE! DOWNLOAD ONLY THE UPDATE AND THE GAME!!(optional)
