Pokémon Diamond and Pearl Versions/Compatibility

Trading exists between Diamond and Pearl Versions through the Nintendo DS's internal wireless connection. It connects to, in the same manner. s received from and its sequels are also sent through wireless. Diamond and Pearl also have the ability to connect to the using Nintendo Wi-Fi Connection, and can also connect to Wii consoles. Due to improvements in international linking, some can have foreign Pokédex entries.

Diamond and Pearl also maintain backward compatibility with the Generation III games; however, standard trading is not allowed. A player's Pokémon may be permanently transferred via Pal Park, and some Pokémon that could previously not be caught can be found using the dual-slot mode.

Also, by connecting to the Wii with a Nintendo DS, players can copy their party Pokémon to their copy of Pokémon Battle Revolution, as well as My Pokémon Ranch. However, only Diamond and Pearl are compatible with My Pokémon Ranch, while Diamond, Pearl, Platinum, HeartGold and SoulSilver are all compatible with Pokémon Battle Revolution.

Generation IV is the first generation with regular Korean releases; every single main series game since Diamond and Pearl have been released in Korean. However, non-Korean versions of Generation IV games did not include a way to view Korean characters, and therefore Korean versions of any Generation IV game can't normally trade with any non-Korean game. If a Pokémon with a Korean name or Korean Trainer name was somehow traded to a non-Korean game, the data for their name would be converted to something else. In Diamond and Pearl, empty spaces were used in lieu of Korean characters. This was changed to dashes in Platinum&mdash;and subsequently HeartGold and SoulSilver&mdash;likely to prevent any issues that may come from a completely blank name.
