Downloading from the Wii Shop Channel
Once you have downloaded the first Super Mario Bros. Game for NES on your Wii, there is a cool cheat you can do. Whatever you last end up as in the game like dressed in a fire ball suit or Mario with wings that's what you'll be when Mario runs across the screen when downloading a game. So if you last end with a fire ball suit, you can shoot fire balls when downloading a game.
Please do not be rude to others, what may be obvious to you may not be to the person asking the question.
