I have a very little bit of insight into how DirecTV's modern cards are implemented, and the fundamental technique does not rely on hardware --- in other words, if you had already been outfitted with a lab that could decap and image chips well enough to generate simulators, the fundamental technique involved would still be expensive to unwind.

BD+ has produced multiple titles which, during their new release window, had no high-quality HD rips torrented. But that's besides the point: if antidebugging and antireversing is such a lost cause, it stands to reason that BD+ should be completely broken by now. But, of course, it is not.
