Hey, we already got a topic on that: http://www.zfgc.com/forum/index.php?topic=38237.0 OHNEVER MIND.Anyway, I'm quite surprised that this problems seems so "common" in comparison to whatever errors previous Nintendo-consoles returned. I read about it on TinyCartridge, too. You might be right with your guess about DSi- and flashcarts, FISSURE. But apparently, this seems to affect normal 3DS-games as well.
