Here are a couple of pic's of the boards. The 2 out side ones are Star Wars, and the middle one is a Empire. Looking at the 5 sets of boards, the small board is what has been added. Not sure on any other thing else. I can go back and look for more details if you need. The added board does say Atari on it. When i bought the 2 games it did have a instruction sheet with it to convert it from a SW. I can not find it right now. Hope this answers some of your questions. Darrell
