Super Mario
This game is a Game Boy Color remake which includes the first two Super Mario games ever released: Super Mario Bros. and Super Mario Bros.: The Lost Levels (Super Mario Bros.: For Super Players). It also has many other collectibles, like images that could be printed with the Game Boy Printer, a calendar, and a fortune teller. Unlike other remakes, it was not developed by Nintendo EAD, but by Nintendo Research & Development 2 (also called Nintendo R&D2).
