Star Fox Adventures

Just keep pressing A like mad. Think of it like a Mario Party mini-game where all you do is mash A. A good way is to lay down the controller and tap the A button with both your index and middle fingers really fast.

Yeah all you need to do is press A as fast as you can until you win. I notice that if you mash "A" before the contest actually starts, you get an advantage than just starting. I would basically try to wrap it up in under 10 seconds, because it becomes more of an endurance test since you naturally slow down after a while.

mash the A button with the controller on the ground

Keep pushing the A- button as fast as you can. If this proves to be a major challenge (For Some Reason), buy or borrow a Turbo Controller and set the turbo to the A-Button.

I rapidly run a coin over the A button.

Rub a pen (non-ink end!) over the A button rapidly. That's what I always did.

If you don't knock the guy off in the first 10 seconds, let yourself fail and try it again.... there isn't much more that you can do.

This can press A like a loco. Also, there some Gamecube controllers with a turbo mode that can help to. Just press A button like crazy and you should win. Its a annoying part I know but you can do it.

Just take a smooth blunt object that fits comfortably in your hand (Such as a Chop stick, pen, Glue stick tube, Crayola marker, whatever works for you) and rapidly slide it over the A button from side to side until you win. Hope you have enough upper arm endurance cause you'll burn some calories!

The best way I've found is to let your opponent start to beat you, let him get a little tiny bit of a lead. Then the game will give you some leeway and you'll have an easier time fighting back, won't have to press A as fast.

When your pressing the "A" button, hold it like you normally would, tap it with your thumb, but when your tapping try not to have your thumb come off the "A" button, less energy is wasted, and odds are, you should win.
