Matt Reichert found a bug in the 400/800 version, and we suspect it's in the 5200 version. Here's what you have to do:
1. Beat the game once
2. While your remaining time is being added to your score (during the
congratulations screen) press reset.
3. Start a new game
What you'll see is that your time is still being added to your score, but it
uses the current timer (which starts at 9990). So you end up with mega bonus points and 0000 left on the timer. I haven't tried it yet but I would assume the timer would start up again eventually by itself if you sat there long enough. Anyway, once you get to the river scene you'll find out that you now have infinite air because the air meter is tied into the timer which is now at 0000. For whatever reason the timer gets reset once you hit the boulder screen, but it starts a 9990 so you'll once again get mega bonus points when you beat the game.
