The American version of Wii came back from donkey kong to run on my Japanese version of Wii. Is the menu garbled?
Main.dol needs to be replaced. You can replace the main.dol in the image with Wiiscrubber 1.40.
Here is a modified main.dolgbatemp.net/t266029-donkey-kong-country-returns?. . & ampSt=45 If you can't change it, then find a modified one and download it again.
