How do you use gameshark codes on GPSPhone? For Pokemon Leafgreen? - enter cheats gpsphone pokemon orange

Hello,
In the experiment, codes gameshark gpSPhone add [a Game Boy Advance emulator on iTouch / iPod.

I do not know if I use bad tricks [Pokemon Leaf Green], either because the cheats dont work, or crashes the game, or is it because I'm not quite sure if I'm doing the right way.

How do I enter codes / What are the codes for Leaf Green?
Sorry, I'm a noob.
Thanks
