This GB is the very first one made. Even though it is not in color it was amusing at one time. At the time when it came out, it had the same games on it as the nes but in black and white unstead. Everyone thought it was handy because they thought it was the first nintindo on the go but they soon realized that it was not in color. The sound is great for such a old thing and the graphics since its in black and white r ok but a little blocky. The only reason i gave it such a high rating is becaus i loved all of the zelda,mario,metroid,and other games on it.
