I recently purchased an otherwise nice original model DS unit to be able to play GBA games comfortably. The only cosmetic issue is that the top screen lens/frame/window has some deep scratches. I've been able to locate an entire replacement shell, or a replacement for the LCD screen inside, but I have had no luck with the simple lens/frame/window. Does anyone have a source? I've even found ones that fit the DS Lite, but they will not fit the original DS screen (too short). Nintendo offers zero replacement parts.
