Mary-Kate and Ashley Pocket Planner (Nintendo Game Boy Color, 2000)

As the name implies, the Mary-Kate and Ashley: Pocket Planner turns the Game Boy Color into a portable organizer, incorporating several features common in popular Visor and Palm handheld "personal digital assistants." The cartridge features a journal, an appointment book, a calendar, a calculator, and an address book. This software isn't all about work, though, as it also contains games, music, and entertaining animations -- just the way that Mary-Kate and Ashley would want it. Important information can be infrared "beamed" from one Game Boy Color, or printed on the Game Boy Printer. A secret PIN helps keep information private. Prominently featuring the popular Olsen twins, the Mary-Kate and Ashley: Pocket Planner is designed especially for girls who are ready to get organized.
