If you want to talk about something, perhaps you should use a better video, not only in terms of quality, but of content. Whoever made it lazily slapped it together with the intent of selling the machine. Also, things with that many games on them tend to be crap.
Well, those are copied versions of classics, such as Pac-Man, Galaga, Donkey Kong, Centipede, Mr. Do, and some obscure games, like Van Van Car, Jumpin' Jack, Shao Lin's Road, etc.. The PCB was made in 2004 by a Taiwanese company, which most people don't know the name of, and there is many different forms of artwork for the machine. There are 55 original games, and there are 5 duplicated games. The 5 games duplicated were Pac-Man, Ms. Pac-Man, Jr. Pac-Man, Pac-Man Plus, and Galaga.
