DS troubles

Okay, I've had my DS lite for a while now, and got an M3 and nopass with it. However, a week or two ago, my ds got dropped, with the m3 and nopass in it. Both popped out, but nothing seemed to be broken. However, now whenever I try to run ds ghames off my m3, it hangs randomly. Real ds games still function perfectly, as do gba games, as does the gba mode of the m3 adapter. I've taken both the M3 and nopass apart, and both seem completely intact. So, why does my ds keep hanging? I can't play ouendan like this!

Oh, I wonder. You've just narrowed it down to being the passcard, you stupid piece of shit. Try borrowing a friend's passcard, see if the hanging stops. Also, try yours in his.
