Just to clear up GameCube Mode, when you put in the Konami Code a menu pops up saying Enable Game Cube Mode with an OK button. Then what looks like a code dump shows up, wait a few seconds and the Toasty guy from Mortal Kombat 2 shows up, and then random images start flying around the screen that you can point and shoot with the Wii Remote. Once they are cleared the credits show up. After words it takes you back to the main menu, no GC mode. Sorry!
