All Multiplayer - 5G (Original Achievement)
To get this Achievement, you can use two methods.
1. Use two controllers and play through all 4 maps (Emerald Hill, Casino Night, Mystic Cave, and the Special Stage)
2. Get a friend to play with you if you don't have a 2nd controller and go through the 4 maps listed above.
Now you don't have to complete the races, you can just start up the race to the point where you can move and then back out.
