A set of 4 games: Super Mario Bros., Super Mario Bros. 2, Yoshi's Cookie, and Yoshi's Egg. I have kept these as a collection of retro games. Operation has not been confirmed. Super Mario Bros. includes a piece of the box that was included when I purchased it, so I will include that as well when shipping. Please understand that these are used items and may have damage, dirt, and odors on the boxes. Thank you for looking.
