In the final mission of the story mode you'll find yourself battling Big Smoke on the top floor of his crack den. After the battle you'll have the opportunity to have free roam of his establishment (after completion you can come back anytime you want). Use your camera or sniper scope to zoom in on the videogame system Smoke is playing when the mission begins (note that there is no T.V. in here but he's playing lol). If you zoom in on the controller you'll see the buttons colored similar to that of a PS2 controller. However you'll notice the top two buttons are labeled "C" and "J" and the bottom two are labeled "M" and "D". I assume these represent lead character C.J. and his client Madd Dogg the rapper. The system itself may also be named after CJ. This is all made more significant by the fact that I cannot see this on any other game system in the state of San Andreas. It may exist but I've yet to see it.
