I hate my DS Lite. The right shoulder button doesn't works anymore, the power switch doesn't springs back in position + it's hard to move, and my top screen gets red and green flickering stripes, sometimes directly when I turn on my NDSL, sometimes after a few minutes. What should I do? Repair this one? Buy a new one, repair the broken one, and have a spare NDS? Or buy a PSP? Or do nothing and just live with the fact I can't play games wich require the R Shoulder button to work?
