Hey all. My friend has a Wii 4.1U and her TV is compatible with just PAL systems. So the Wii has no colors. On the screen it's just a grayscale image. I was wondering if I installed 4.1E, would the problem be fixed or does he need new hardware in his Wii? And if it does need just 4.1E, how do I do it... By WAD installation or what? Will all the data be erased?
