I've had my store copy of Brawl sitting around all day because I've been waiting for an update. Well I got bored and threw it in to test it since I read on another forum I visit that a legit copy worked for someone. To my surprise, I put in the copy, had a prompt to update, and after that the Wii restarted and the Brawl menu came up. So before doing anything hasty like corrupting your Wiikey, just check to see if your copy works. I am so happy right now!
