Star Fox 2/Controls
From StrategyWiki, the video game walkthrough and strategy guide wiki
You can select the control mode on the character selection screen by selecting the D-pad icon () and cycling up or down through the modes. There are four modes: A, B, C, D. Modes A and B use the same buttons for the same actions, so do C and D, the only thing that changes is that in modes A and C the flight controls are inverted on the Y axis (pressing will make the ship / aiming steer upwards and pressing will make the ship / aiming steer downwards), whereas in modes B and D they are not.
