There have been a lot of complaints in this thread, ironically, about the thread itself. I think it's great that it's still going as it serves a purpose: It's a great diversion while we ALL wait to see what will happen next.
Is it a CRC check? Is it a bug? Is it several different things combined?
Will firmware programmers find a way around it, or will someone have to patch the ROM? What if neither of those options solves the problem?
Why would R4 care about this? Haven't they already made a boatload of money? At this point, they can still sell their product and say that it works with almost 100% of commercial games. That will change if this is a deliberate attempt at anti-piracy, as other companies will likely adopt similar methods.
What did you all expect? I mean, if this is deliberate, then it's way overdue. Right now, DS flashcart piracy is far simpler and cost effective than anything similar has been for any console EVER. Of course the game manufacturers are interested in anti-piracy measures--just look at this thread, with all of the views and comments. This is just over one game!
All I'm really saying is that something will happen, one way or another. The R4 has been showing it's age lately, and the newer flashcarts are looking better all the time. It may just be a good time to upgrade...
