Cartridge Only Unlike other game versions of the first Harry Potter book, the Game Boy Color rendition of Harry Potter and the Sorcerer's Stone is a traditional roleplaying game, complete with NPCs to talk to and random beastie battles to challenge you. The game begins with the receipt of an acceptance letter into Hogwarts School of Witchcraft and Wizardry. From there, you (as Harry Potter, of course) will go shopping for your school supplies, catch the train on the 9 3/4 platform, take a boat ride, and finally arrive at your new home.
