System Shock 2 has an item that is a portable game system, and one of my favorite is Overworld Zero. Does this game exist independently outside of System Shock 2?

ps: I spend so much time in game playing this my co-op buddies rush to grab all the game systems and trash them to prevent me from playing...

    This is at least halfway a software recommendation, if not most of the way.
