You can use Visual Boy Advance for GBA Emulator.
It has the option for setting the cheats either Game shark or code breaker

ty vm much but i tried that and it doesnt seem to work

You may need a Master Code to be active.

VBA doesn't require a master code.Check your origination of the game, europe or american, and check your codes. If you have (EU) in your game, you will need european codes. Likewise, if you have (AM), (American), etc., you will most likely need an american code.
