I am using USB Loader GX r872, system 4.2 and i am trying to play super smash bros brawl. Whenever i select it it gets to the first now loading screen then freezes at a blank white screen. I have to turn off my Wii because it completely froze. I have tried to load it with IOS 222, 223, 249 and 250. Are there specific settings to get this to work? any advice on getting it fast first loading screen?
