I bought my DS just before Christmas, it's the Mario Kart pak.
I was playing Metriod Prime Hunters today, shooting at Gorea in the final battle and I'm using the right hand stylus control. The left shoulder button being my fire button. It ain't firing anymore? It's gone dead.
Anyone else got this problem and what do I do? take it back to the shop where I bought it? I don't have the receipt. Will Nintendo replace it? It's only six months old!!!
