I don't thnik it's some weird Chinese thing unless it has some form of odd content that's not regularly featured. My theory(which could be incorrect)is that your catridge is inserted at an odd angle or something. Maybe it needs to be clean? On my DS and GBA, I've had experinces where the game acts funny and does these things. Maybe you're accidentally and slowly moving the cartridge during play(or is this a DS game XD)? I suggest blowing it,cleaning it, or if you're REALLY desperate...licking it. Yes. I've found that too be highly effective(but I'd be careful about that if it's used >__<). I hope this can be of some help...
