This is an unopened Nintendo DS video game called Retro Atari. I do not own a nintendo DS and I have not opened it so I have no idea if it works but I do not have any reason to think otherwise. 10 original Atari games, including Pong, Missile Command, Asteroids, Breakout, Centipede, Tempest, Warlords, Gravitar, Lunar Lander and Sprint.
