Nintendo has acknowledged a flaw in the DS Lite that could leave some with a cracked case. Some DS Lite handhelds are showing cracks in the left hand side of the case near the hinge, just above the power connector. Nintendo claims the flaw is rare only affecting 0.02% of the total number of DS Lite handhelds shipped.
It seems unlikely that 0.02% is an accurate number, especially since pictures were spotted at a Nintendo store of DS Lites with cracked hinges. Either way, they will fix it for free as long as it’s under a year old.
