Yeah, I catch you, Wymsy.
From how I see it, the problem is most likely caused by game abuse (i.e. instead of softly blowing on the outside metal stripes if it's not reading, blowing harder, or even spitting on it, which I have heard has been done, and not because of AR/GS codes). If something doesn't even read, AR or GS would have positively nothing to do with it (it's possible that the save data could be erased, albeit unlikely, but never cause the game to be unreadable).
I figured maybe he just got candy/dirt/whatever on the metal strips or his DS is being retarded.
That's what I think also. Softly blowing on it usually works 1st time, and occasionally second time, and I've never had to do it more than 3 times. Have him try that - softly
blow on the metal strips (with the emphasis on softly
), and if the game still continues to not read, I'd say that the metal strips have been damaged somehow.
