Pokémon HeartGold and SoulSilver

Pokémon HeartGold and Pokémon SoulSilver are 2009 remakes of the 1999 Game Boy Color role-playing video games Pokémon Gold and Silver, also including features from Pokémon Crystal. The games are part of the fourth generation of the Pokémon video game series, developed by Game Freak and published by The Pokémon Company and Nintendo for the Nintendo DS. In commemoration of the 10th anniversary of Gold and Silver, the games were released in Japan on September 12, 2009, and were later released in other regions during March 2010.

HeartGold and SoulSilver take place in the Johto and Kanto Regions of the franchise's fictional universe, which features special creatures called Pokémon. The basic goal of the game is to become the best Pokémon Trainer in both the Johto and Kanto Regions, which is done by raising and cataloging Pokémon and defeating other trainers.
