I recently used Gameshark's Pokemon Modifier code to get Celebi, Feebas, and a few other rarities. However, I don't really know how it works. I did what it said to do, and nothing happened. When am I supposed to use the code? In battle? In tall grass? In the menu? On my PC? Also, does the Pokemon just appear in my party/PC, or do I have to fight and capture it? Thanks.
