On my way to U-Haul to pick up more boxes to pack, I couldn't resist checking the near by thrift stores. I found Action Arcade Adventure Set book with the disk. It is a book about creating arcade games in C. I don't know if it is good or not, but it is thick and was only 2.12. My other find was Superman (with the box, no instructions) for the Genesis. It was 3.99.
