There is a saying: the drama stops where the buck also stops: where it counts, and where it hurts. There must be a reason why the video of the supposed PS3 ISO Loader "is no longer available", and that's because, in an important sense, there's no such thing to begin with.

Enter Nevada, QJ forum member, who is trying to clarify this entire issue over there. Long story short (long story in the forums, by the way), the videos are what we could call proof-of-concepts, a "Hello, World!" if you will, of the exploit that was found. Interpreting Nevada's post (and subsequent posts) in the forums, neither he nor those he had worked with (it's probably a team since he uses "we" at some points) intend to use the exploit to develop their own ISO loader. He even points out that Paradox is working on theirs, anyway.

It is possible that part of the confusion that arose over the exploit vids came about because the intent behind them was never clear - just a "Hello, World!" with no further development on the part of those who discovered it to flesh out into a loader. In fact, they "have informed Sony" of the flaw in question. Nevada goes further (verbatim):

infact for the sake of the argument, i'd like all of you to just assume the videos are fake if you've no intrest in them other than "omg i want to pirate games", to anyone who is actually intrested in running your own code without 'all' the hyperivsor restrictions, theres enough in the videos to give you a good start.
