I use Wup Installer GX 2 to install games, most of them can work, but only Mario Kart 8 & Mario Party 10 can't. Both of them just freezes at the loading image. Mario Kart 8 also makes a terrifying noise. And Mario Party 10 just keeps loading... (the music still runs though...?) Not sure why this happens... Is it the file I downloaded was corrupted? (I use Wii U USB Helper to download and transfer to SD card) or maybe sometimes it fails to install...?
