If you used Raw Dump to create your image you should have a .iso file that is ready to go. If you used one of the older applications or some other method that produced a ".wii" or some file type other than a .iso you'll need to convert it to a .iso using either Rawdump 2.0 or Unscramble 0.4.
If you are unsure whether or not your file is scrambled you can run the unscramble function of either of those applications. If the file is scrambled they will unscramble it, if the file is not scrambled then they wont harm it.
Another way to check is to look at the file sizes
- If the file is 4,699,979,776 bytes, it is unscrambled.
- If the file is 4,700,012,544 bytes, it was unscrambled with unscrambler 0.4 (unscrambler adds 32,768 bytes to the file).
- If the file is 4,736,698,368 bytes, it is a raw file and must be unscrambled.
