Mario Kart: Double Dash!! Cheats For GameCube
Turbo Boost after Lakitu Retrieval
If you fall off the track or get stuck underwater for more than a couple moments, Lakitu comes to pull you out and place you on the track again. When he picks you up, wait until just before you touch the track again, then press the acceleration and you'll get a turbo boost if you timed it correctly.

Mushroom City Quick Boosts
As you may have noticed on the Mushroom City course, among the traffic are vehicles shaped/colored like the Mushroom items. If you run into them, you don't spin out like you would against other cars; rather a Mushroom is thrown from the back for you to collect/use for a quick boost!

Pipe Plaza Glitch
In the balloon battle mode on the Pipe Plaza map. if an enemy hits you into a pipe with their weapon, and you are thrown through the pipe then you will not lose a balloon. Instead, you will come out of the pipe with stars around you and it will appear as though you just drove through the pipe.

Japanese Contest code
After completing a Time Trial race (When it says Retry, Change Track, etc,), press L,R,L,R,X,Y,X,Y,Z. The code that pops up was for a Japanese contest. Totally useless, but it's interesting that they forgot to take that out.

Mario Circuit Goomba Boosts
If the Goombas on Mario Circuit are hit with a turtle shell, they will be squished into the ground and a boost will fly off them. If a thunderbolt is used on the course, it will squish them all and there will be several boosts lying in that area. It doesn't work the same as the mushroom cars; if you hit a goomba they stay solid and you spin around a bit. Turtle shells are you're best bet.

Rainbow Road Falling Stars
You may have noticed there are a lot of stars on Rainbow Road. And many of them fall. And some of those that fall fall on the track. Where those stars fall, they turn into star items, just sitting there. Some of these are dangerously close to the edge, but if you can get one (especially when you're already near the front and there's no other way to get one) it's a nice bonus. Only problem is that they're the same color as banana peels, so be sure before you run over something yellow!
