I need to update to 4.3U, what's the safest way? I was contemplating using Waninkoko's Updater, but it seems people have been renouncing it lately. And I tried just updating the Wii Shop itself, but I'm guessing I'm missing some system IOS's that it needs, because it keeps telling me that I have to update my system menu. Thanks in advance. -BTW, only updating to get some DLC for DJ Hero.
