Wild Choppers Cheats (Nintendo 64)

To defeat the boss in Mission 6 easily (the big green plane) make sure you have plenty of
the fat
  green missiles. Then you want to get underneath the plane and shoot as many upward as
possible at a time. Do this a while and he will die easier than trying to get a lock on
him. For the other planes,
  buy some big red locking bombs and just shoot a bunch of 'em at him.

While playing, press Z + C-Up + C-Down, then launch a homing cluster at your opponent. If
it hits,you will see the president jump out of the plane.

At the "Press Start" screen, press C-Up seven times for level select.

Beat level 7 on expert mode to get the alien disruptor.
