Pokémon HeartGold & SoulSilver

Pokémon HEARTGOLD AND SOULSILVER

Pokémon HeartGold Version (Japanese: ポケットモンスター ハートゴールド Pocket Monsters HeartGold) and Pokémon SoulSilver Version (Japanese: ポケットモンスター ソウルシルバー Pocket Monsters SoulSilver) are paired Generation IV remakes of the Generation II games Pokémon Gold and Silver.

Much like how Pokémon FireRed and LeafGreen revisited the Generation I story of Kanto, HeartGold and SoulSilver retell the story of Johto, with the player's starting town being New Bark Town. While the games feature several expansions in key areas, the overall plot follows the same direction as the original Gold and Silver. Some aspects exclusive to Crystal are also included. Like how FireRed and LeafGreen could link up with Ruby, Sapphire, and Emerald to complete the Pokédex by trading regionally exclusive Pokémon, HeartGold and SoulSilver can link up with Diamond, Pearl, and Platinum to obtain Pokémon unavailable in Johto and Kanto (such as the Sinnoh first partner Pokémon) and vice versa.

Kris, despite being the female counterpart of Crystal's player character, is not included as the female player character, with a new character instead taking her place. Whether she is chosen to be the player character or not, this new character will still appear in the game. The unselected protagonist will take a pseudo-rival role similar to the unselected characters of Ruby, Sapphire, Emerald, Diamond, Pearl, and Platinum.

The games were released on September 12th, 2009 in Japan, February 4th, 2010 in Korea, March 14th, 2010 in North America, March 25th, 2010 in Australia and March 26th, 2010 in Europe (this excludes the Netherlands, and the Flemish part of Belgium due to an in-game save error, with the patched copies later released on April 2th, 2010).

Game director Shigeki Morimoto aimed to respect the feelings of those who played the previous games, while also ensuring that it felt like a new game to those that were introduced to the series in more recent years. The games have received positive reviews from critics, and as of March 2014, the games' combined sales have reached 12.72 million, making the two games combined the eighth best-selling DS video games of all time.

In HeartGold and SoulSilver, the Pokémon in the first slot of the player's party can follow them in the overworld, echoing a mechanic in Pokémon Yellow where Pikachu follows the player. This mechanic was also used in a limited fashion in Pokémon Diamond, Pearl, and Platinum when the player is in Amity Park with a "cute" Pokémon. The player may talk to the Pokémon to see or check on how that Pokémon is feeling, and occasionally it may pick up items. Additionally, a pedometer was bundled with each copy of the games called a "Pokéwalker", which allows players to transfer Pokémon from the game into the device and walk around with them, earning "watts" in the process, which can be exchanged for in-game rewards.

A new minigame called the Pokéathlon uses the Nintendo DS touchscreen and allows Pokémon to compete in events such as hurdling. The Japanese versions retain slot machines found in previous games, while the international releases of the titles replace the slot machines with a new game called "Voltorb Flip", described as a cross between Minesweeper and Picross. Another new item, the GB Sounds, changes the background music to the original chiptune music from Pokémon Gold and Silver.

A new mechanic in the Safari where the player can customize areas to increase the rate of wild species to appear was also added. The entire mechanics will be unlocked after having gained the national Dex, completed two quests by the Safari administrator and automatically answered to each of his calls (one-each 3 hours of game).
