Wired-Up Retro released this interesting video that looks at details of Atari 2600 controllers that have remained hidden from many an Atari fan. You are about to find out what very few people know... and it's all for the sake of fun
Here's a summary of some of the secrets that will be revealed in the video...
1) the Atari CX-22 Trak-Ball has a desirable feature that the later-released black CX-80 Trakball doesn't have. In fact, there are other 2600-compatible trackballs that have this feature as well...
2) The combo paddle/joystick 2600 controllers made by Sears and Coleco are not as effective to play paddle games on a light sixer or heavy sixer unless you have a particular item to use with the controller. There are some people here who may have never known about this.
3) Omega Race is a two-button game requiring a special "Booster Grip" to properly play it. Some may not have that Booster Grip, but there is another way to play the game... and a controller from another gaming console is the key.
4) There's a particular mouse that can be used to play 2600 games, but there's a trick that you have to know in order to make it "active".
