I have figured out a possible way to fix a 003 wii that currently has the USA system menu and setting.txt stuff. I am using a hacked ( but not fakesigned ) copy of SSBB to trigger a "bug" in the recovery menu and then it will boot the retail copy of the disc. My hacked iso is 7.1GB, but i think this will also work with a 500MB iso. This means that, in theory, anybody with a modchip may be able to fix these wiis. Though, I have not bothered to burn this disc to test, so I only know that it works running from a wode. The problem is, I don't have a korean wii to test this out on. Does anybody have one they would like to donate to the cause? I will gladly send it back when I'm done with it.
