One of two things:
1) you have a bad dump. If that's the case, you're up a creek, and need to redump the game. (you can check if its bad by checking the MD5 hash)
2) It's just that point in the game where it's creating a savefile. It's a pretty slow part on the first run, and if the first run was interrupted the save file became corrupted. You need to delete the Wii save file and try again.
