Maui, or anyone else...
I followed your guide and everything went down perfectly.
Now with my moded wii, when I try to play Super Smash Bros Brawl, when I win the first fight on adventure mode, the screen freezes in black, and the only way is to power off the videogame.
I know it's not the ISO, it works on my friend's wii.
I tried loading the game with the 248, 249 and 250 cIOS's.
