NES Atari 2600 gamepad review. http://www.ClassicGameRoom.com Classic Game Room reviews the Nintendo NES Atari 2600 controller gamepad! This Nintendo controller (custom it would seem) has been modified to play video games on the Atari 2600! Since both buttons do the same thing it is not an ideal Atari 7800 replacement controller. Enjoy Nintendo classics on your Atari like Mario Bros. by playing them with an NES gamepad that has an Atari plug!
