Use ModMii; the link is in my signature.i have a softmod wii in 4.2 and i like to update to 4.3 how i do that
I'm so lazy tonight that I don't even feel like writing out all the negative affects you neglected to mention, lol. You could probably just google my name and find a billion posts where I have listed them.no u won't lose anything
btw, it's pointless to update from 4.2 or 4.3, u gain nothing in doing it. The only change it makes is you get to see 4.3 instead of 4.2 in the wii settings menu.
