Tottoko Hamtaro: Tomodachi Daisakusen Dechu — About this game
Visit Hamtaro at different times for greetings and playful condition checks. The desk begins with a personality book, while other books and functions appear as you keep playing. Add people through the book and review their cards, including the reverse side. Later tools compare compatibility and display rankings. The original cartridge can exchange friend cards by infrared; its main activity remains a single-player profile and fortune-telling experience.
