Pokemon Emerald Guide (Battling,buildings,items, buttons)

Battling: wild pokemon: wild pokemon will jump out at you in tall grass or water. You can surf on water later. You can't now. The pokemon you will see change the farther you go. Once a pokemon jumps out at you, You will have to throw out your pokemon and come to a menu of four things:
Fight: This brings you to a menu of your pokemon's moves that it can do. A pokemon can have 1-4 moves. Moves can inflict damage on a pokemon. If you inflict alot of damage on one pokemon, it will faint, and you win the battle. however, If the other pokemon makes your pokemon faint, you lose and get transported back to the PC Center you last used. Same with trainer battles.
Pokemon:This will bring you to a list of your pokemon. If you want a different pokemon to come into battle, select this, select the pokemon, and select shift.
Bag:This will bring you to a list of items that you have. You can select any item you want to give to your pokemon. Look in the items section of the guide.
Run: You should do this when your pokemon are either tired, or weak against the pokemon that jumped out at you. You will have less chance of getting away the weaker you are against them. You cannot do this during trainer battles.
