Yeah, definitely try the Game Cube controller. You can still get a boost off the line, but the timing is really weird. You basically start gassing in between 3 and 2. And keep on the throttle, then quickly let off then push the throttle when he is in between 1 and green. If you get the timing right you will get a good boost. If not, you'll either burn out, won't get a boost at all, or get a really weak burst off the start. Either way, when you play online, any little boost off the start helps since most everyone runs the wheel and gets drifting in corners with random power up boosts.
And yeah, we'll see how that goes, hoping for the best though.
I added you online. But we can't race until you add my code.
