The listing, 2 Mary-Kate and Ashley Gameboy Games has ended.
This are two games are used but I've gone in and deleted any info I can (there may still be some highscore or saved games I couldn't access from the main menu). I do not have any of the original packaging but both games are in great condition. For more info on the games themselves please read individual descriptions below.
Mary-Kate and Ashley: Girl's Night Out:
"A girls night out filled with hip fashion and some hip-hop dance moves. First, you've got to have the right look to get into the club. Then it's time to dance the night away. Girls Night Out will challenge you to repeat a series of key-press patterns to the game's music. Dance well and you'll unlock new dance moves, new songs, and even clothes. You can also rock the house by playing DJ for the club. The game lets you create and save your own music mixes from techno, house, and disco clips. "
Mary-Kate and Ashley: Sweet 16 - Licensed to Drive:
"Fraternal twins Mary-Kate and Ashley Olsen have their real-life 16th birthday celebrated in this Game Boy Advance title, which differs from its similarly titled console counterparts. The object in this game involves driving around town from an overhead perspective while running errands for friends and family. Completing these tasks earns players money so they can save up for the party to end all parties. Players must also drive safely, avoiding accidents and wrong turns, or risk losing their license by receiving three tickets from the police.
The driving scenes primarily involve delivering passengers within a time limiti. In between missions are a number of mini-games waiting to be unlocked, including both ATV and jet-ski races, an Earth Day celebration that has players racing to pick up trash, and a trivia contest to test a player's knowledge in a variety of topics. Three modes of play include Adventure, Arcade, and Multiplayer. A password feature lets players resume their quest for the ultimate celebration: a Hollywood movie premier."
