Need help fixing my game by changing my location with ar for pokemon Heart Gold

[Monkey D. Luffy]

I saved my game in the mystery zone, and now when i try to start it the screen goes black. After pressing continue on the main menu, it just goes black. I want to try changing my location with pokesav, but i dont know how. I have it for heartgold, but need help using it. Any other ideas are also appreciated. Thanks

Okay, ive been doing a little work and have reached a new stage. i made the code, but when i press L+R the screen goes white and the game reboots. What to do know?
