What are the rules? Your playchoice version has a timer and is the same as the Nes version, isn't?
The timer has nothing to do with the game play.
When you threw in a quarter you added 300 "seconds" on the timer.... the picture was taken before i put it on freeplay... now it rests on 9990 seconds all the time...
The Play Choice is a "NES in a Box" (or close to it...)
But i think the version you have is pretty close to mine.....
