you use a game shark
You can't just type cheats into the game. You have to have a cheating device that load the cheats into the game, and then gives you a button sequence to activate them. (This, method describes the Action Replay)
L+R for most
get an action replay and just activate the cheats you want its easy
not for emerald but for Pokemon silver for Gba
you can get arceus cheats
You need the action replay to activate the codes.
Go to www.cheats.it
No Pokemon game has cheats sorry.
you don't
Do you need a cheat for Pokemon crystal? cuz I have thoze.
you can't... there are unlockables and hints, but there aren't really cheats... if you have an action replay code thing, you can activate any cheats, and if you have an r4, all of the Pokemon games come with cheats, but with just the game there aren't cheats
Look up cheats put them in and then u push the buttons to activate the previously stated cheats while in the game
