As mentioned in the other thread, I don't think you need to use the save game exploits any more. Have a look at http://wiiguide.co.cc/ It is using something called a bannerbomb. As soon as you try to access the SD card with the software loaded on it the Wii tries to open a banner message and the code on the SD card uses this to launch itself and bomb the process and hack the Wii. Very smart if this method works.
