At the level select screen with the globe, highlight Russia and press Right. Hold X + Down/Left before the Japanese mission details appear. The globe will begin to bounce through the levels. To choose a level, release the buttons when the desired level is selected.
On the final level (Japan), when the shield generator is blown up, walk into the center of the explosion for a hidden level and the true ending of the game.
