Recently, I just got a shiny magnemite in Heartgold, and I went back to see if I could train it at Mt. Coronet to evolve into Magnezone. I haven't played Pearl around a year, so when I started my ds with Pearl in, the start up screen froze. It seems that when I put that particular game into my ds (not any other game, I've tried ), it freezes to where the little boxes that float from the o in nintendo stop moving, along with everything else. I've cleaned the gold strips at the end of the cartridge with rubbing alcohol, waited for it to try, but sadly, nothing changed.
Hoping for a possible solution , (contacting Nintendo is my last resort)
