Ok, I have used the 3-in-1 for a while, love it. However, I've gone through the games I wanted to play on it for GBA. Is there a way to blank out the last game on the card? Empty, like the way it arrived? I know it isn't a big deal to have a game on there that I'm not playing, but it helps me keep track of all the stuff I'm playing if I go to load the 2nd slot and get a "no cart" message... just saves a power cycle. Thanks.
