Hi all,
I spent a good few hours tracking down a bug so thought I would share. My game (such as it is so far) worked on windows but hung on the Wii. Eventually I tracked this down to fatInitDefault() hanging, and was kicking myself as I have had probs with this function before. Anyway, the cause of the hang was the USB camera for the game "Your Shape" was plugged in. Unplugged the camera and everything just worked :-)
Hope this helps someone!
