I have the new brighter GBA SP (the one with the backlit lcd like the ds lite) I just noticed at times if you look hard enough it looks like the screen is interlacing. Now I tried looking up specs or googleing gba and interlacing and find nothing. Is this thing interlaced or is somthing wrong with it? I ask cause my manual states if you see lines during game play please send your unit it for repair.
In case somone else is questioning this as I was. It is normal. I went bought a new one does the same thing took it back exchanged for another does the same thing, returned all and kept the one i already had.
