I found a glitch in pokemon D/P! Use the walk through walls cheat and go to darkmoon island or where ever darkrai's place is called. Keep going through a certain wall, and look for complete darkness. Go into the complete darkness and save there. Turn off the game and you are stuck there. I don't know how to get out though.
Maybe there is another cheat to get you out. Anyways, I didn't do this, my dad did. He played my pearl, but after he messed up, he fixed it!
I was so happy after he fixed it! Has this happened to anyone before.
