Hey guys, trying to surprise my brother for his birthday by modding his Wii U and also adding skins to super smash. So far I've modded the system and am able to play the games off of an sd using loadiine. I'm now stuck trying to use a mod pack I found on YouTube. It's made by NRG Nairo. He doesn't give instructions on how to use it and I can't figure out how to make it work with my backup. Any help would be greatly appreciated.
