Well, I do not think that such a booter exists...
I have seen this Wii AR before (youtube vids etc.) but never managed to obtain it.
At a first glance, it looks to be encrypted. My guess is that Datel probably did this to stop us homebrew type of folk from messing with it, and mainly to prevent people from getting this Wii AR for free.
(Datel really likes peoples' money, even if they stop product support not long after releasing said products, or are using freely available homebrew exploits to get said money, but I digress.)
Unfortunately, I do not have the knowledge to try to decrypt it I am afraid...
However, if someone were to decrypt it, it should be possible to boot it however you wanted to then.
