So I have a softmod 4.1U Wii. All I want is a USB loader that will load games from a USB hard drive in ISO format. I have tried Wiiflow, Neogamma, and USB Loader GX. Neogamma is on it right now and works when using backed up discs. The three loaders I tried get stuck when trying loading a game. The screen is blank and the Wii must be powered down by the console button. Am I missing cIOS or something? If so, could someone guide me through the process? I would prefer to get Wiiflow working since it looks the best. I don't know what I am doing, so don't talk too technical.
