Pokémon Emerald Version is a 2004 RPG video game for the Game Boy Advance. It is a third, "enhanced" version of Pokémon Ruby Version and Pokémon Sapphire Version, in the same way Pokémon Yellow Version: Special Pikachu Edition was an "enhanced" version of Pokémon Red Version and Pokémon Blue Version. It features limited ability to interact with the Nintendo DS, including interactivity with the DS game, Pokémon Dash.
