Mario Kart: Double Dash!! Tips

Double Dash!!
Here's the way to make a double dash:

You must play in co-operative mode with a friend. When the race begins wait until Lakitu's light turns green. Your friend and you must press the "A" button at the same time. Eventually, you'll get a double turbo called "double dash". This only works if the two players press the button at the right and same time!
