What are some Pokemon Emerald cheats?

There are other good cheats other than that!

You should always start with the beginning of the game!

• First-In order to do this cheat you have to have a second gameboy,something to connect both of them,and another game (sapphire,emerald,etc..)
• Second-In the beginning of the game,help Professor and take any random Pokemon he gives.Battle with the Pokemon and win.
• Third-When he gives you that Pokemon after you win go to Oldale town after he talks to you and blah blah.
• Fourth-Once in Oldale go to the PC and trade that Pokemon with another Pokemon.Make sure the other person trades you a Pokemon they don't want!
• Fifth-Restart the game and battle that Pokemon attacking professor again.This time select another Pokemon than before.
• Sixth-If you keep doing this than the other game will have all three Pokemon you could have started with.
• Last-When you are done,re-do the game and play it and trade back those other Pokemon you traded in the beginning of the game.

Now you all three Pokemon!
