I am sorry, but at this time the error can not be fixed.
The only fix that works is "Indiana Pwns" but it would have to already be installed on the wii, which is doubtful.
The only this you can do is autoboot many NTSC-U games, many will play but not all. Then wait, wait, wait and wait some more until a fix is made available. It will probably be fixed someday, but it will probably be awhile.
When a fix is found, I will post the solution HERE-
