Every time I load PAL games using USB loaders on my US Wii, they always freeze failing to load the game. The Wiimote automatically turns off and I have to hard reset the console (long presses the power button). For example, Just Dance 2014 freezes on the "Reading disc..." screen (though the dots continue on animating), and Skyward Sword's only static black screen (like having bad tv reception). Other NTSC games work fine. I haven't been able to test their NTSC versions, so I don't know if the problem is region lock. Any advice?
