HUNT FOR THE RED OCTOBER, THE Submarine power-up: To power-up your sub during the game, pause the game and then press A, B, Select, A, B, Select, A, B, Select, A, B, Select, A, B, Select, A, B, B, A. You can only use this once per game, so use it wisely. Jump levels: Another cheat which you can only employ once per game is this level skipping one. Pause the game and press A, B, Select, Right, Left, Left, Right, Select, B, A, B, B, A. Pause the game, then enter these codes (L = Left R = Right U=Up D = Down): START A B SELECT R L L R SELECT B A B B A START to skip to the next stage (you can do this once per game) START A B SELECT R L L R SELECT B A B B A START use when you have 0 subs left to get more START A B B A R D U L L START double point values U D L R U D L R U D L R A B B A Slow down auto-scrolling U U D D L L R R no auto-scrolling U D L R SELECT no "sliding" to a stop Full weapons: START, then A B SELECT 5 times, START. Note: If you wait to use the stage skip code until your Subs count reaches 0, you will have tons of 'em. The count will still say 0 when you continue playing, but after you lose a life it will say 10.. and it will go on and on for a VERY long time.
