Pokémon Emerald Tips

Long but worth it!
When you are able to go to the Battle Frontier Keep battling until you have a lot of battle points. Then go trade them in for things like protein and hp ups. Then go sell them. If you have 70 battle points and sell them all, you will end up with $343,000! It takes a long time but worth it do things like battle dome or Battle Tower Single so you can get multiple Battle Points every time you enter.
