So I decided I wanted to just get a bunch of master balls cause I'm tired of trying to catch Moltres. I used a cheat in GameShark for a master ball item to be purchased at any Mart. However, instead of that, I can't buy anything, ha. It just flashes and then the lady says "Can I help you with anything else?" Has this happened to anyone else? Is there a way to fix it? Thanks in advanced.
