Set of 4 Pokemon games for Game Boy. - Game Title: Pokemon Red - Game Title: Pokemon Blue - Game Title: Pokemon Yellow (Pikachu) Thank you for viewing. I sell a lot of retro games. I enjoy playing and selling them myself. Please read my profile before purchasing. [Game cartridge only] These are products from about 30 years ago, but they work fine. I have confirmed that the software starts up on my Game Boy. Please check the photos as well as the description, as I provide as much information as possible.
