Hidden Level:
You can immediately access the N64-exclusive "Gecques Cousteau"
(Titanic) level without having any remotes. When you first start
the game, go straight ahead to the arch that you can climb on.
Go halfway up the left side (the level will turn upside down),
stop, and go forward off the ledge. If you did this correctly,
it should let you walk off the edge and onto the top of the arch, where
you will see a platform. Jump onto this platform, and it will take you to
the entrance of the level.
