Despite what you hear the occasional Acekard user complaining about, it's about 99% fixed. There's the occasional crash, someone mentioned they experienced two black screens from the beginning of the game to the Elite 4, but it's nowhere near the 22, or 3 event limit that the rest of us run into. The same poster also mentioned one of the crashes was likely due to his card shifting in his pocket since he didn't crash in the middle of an event. I'd be damn happy if I could cruise through the game with 1-2 crashes.
Also, to all the current posts going on, I've been following these posts all day long. If you want to see where people got somewhat productive, check out some of the posts in the page 100-120 range. The problem might lie in an overload in a section where the system should be reading in 16 bits, but only reads in 8 bits and therefore can't load the image. That's the most interesting piece of speculation I've seen in the last 12+ hours.
