Dead pixels..... meaning.... when you turn on the game and start playing, are there little black spots on the screen where there should be color changing pixels.
The game screen displays thousands of tiny little pixels which combine to display the game graphics. In old hand held systems, dead pixels can be a problem. If there are one or two dead pixels, its not a big deal (almost unrecognizable). But if the number of dead pixels reach the hundreds or thousands, then it will effect the game play
