How do you erase your catz clan account

I figured it out. When you turn on the DS and select the DS game to play, the first thing that appears from the game is "Licensed by Nintendo" with a white background. When that is on the screen (its there for about 3 seconds) that's when you push the button combo L, X, B, SELECT all together at the same time. Then it will ask you if you want to start a new game or not.
