Pichu Event?

[pokefan1412]

Hi first of all I'm new and I'm sorry if this is in the wrong spot. But anyways I'm looking for an Action Replay code for Pokemon Heart Gold that gives you the shiny pichu from the game stop event (a short one if possible) and I don't know how to use my action replay disc thing yet so don't suggest me to use that unless you can also explain it to me. Oh and explain what the action replay code does too. Like if it deletes the first pokemon in your party, go to pokemart, delete a pokemon in box etc. Oh and this has already happened to me but please if you give me the code make sure its not a bad egg... It already has happened to me once and I got rid of it. If you can help thanks alot, if you can't thanks for reading this and maybe you can help in the future. Thanks for reading! :3
