You can exploit the N64 controller's "Neutral position reset"; feature easily in this game. What you do is hold down on the control stick, then simultaneously press L+R+Start. What this does is set the "down" position on the joystick to neutral. So what happens when you press up? You go REALLY FAST! Problem with this is that the neutral position is now "Down." To fix it, just let the joystick go neutral, then press the button combination again. This works GREAT in the first hidden level, "Outpost Omega" when trying to do the switch puzzle to get the artifact.
