Pokémon Emerald Version

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.

Gameplay
The player controls a Pokémon trainer, whose general goal is to traverse around the Hoenn region and conquer a series of eight Pokémon gyms to earn eight Gym Badges, then take on the Elite Four, defeat the Pokémon League Champion. The game features the third generation Pokémon, but also adds some second generation Pokémon that were once limited to Pokémon Colosseum. The National Pokédex is also available without trading. The game adds Battle Frontier, where the player can enter a variety of areas with different Pokémon competitions.
