This feature allows you to move favorite Pokemon, Legendary Pokemon, and many of the other tools that you have found useful in other versions.
Team Aqua and Team Magma are heavily involved in the game and after waking their Pokemon a battle begins that the player must stop. The Battle Frontier contains 7 buildings that each contain a different style of battle, rental Pokemon, random rooms, tournaments and more. Having played the other Pokemon games, I found that this one provided the most challenge and entertainment. It was especially fun to be able to trade versions and be able to breed Pokemon. This took a little practice and some reading on the Pokemon boards, but once you have developed a technique you can quickly increase your Pokemon. I quickly learned that breeding two different Pokemon could lead to unexpected results. If you enjoy Pokemon, then Pokemon Emerald is a natural, and great next step in your gaming.
