A few months ago the calibration on Sushi K DS Lite went off, WAYYYY off. Sushi K tried everything to fix it: calibration, the toothbrush, the needle, nothing had any effect. So Sushi K bought a triwing screwdriver and opened her up to see if he could clean anything. she couldn't. Sushi K found replacements on ebay and opened it up to see how hard it would be to replace. In the process Sushi K broke the touch screen completely. That decided it for her, so Sushi K bought a generic replacement.
