Cheat Menu
Go to the password screen and input the word "special". You'll hear the sound of Prince being hit and nothing else will happen. Exit this screen and start a new game. Pause the game and then press buttons in this order: B, Y, Up, Down, Left, Right, L, R, then press Start + Select to enter the cheat menu. In the cheat menu you have level select, sound select and boost meter, which increases by one, as many times as you wish, the maximum ammount of life you have. Also, during any battle, if you press X, the enemy you are facing will die. Note: this code does not work for the PAL version of the game.
Maximum Bottles
There are two sections and two bottles in level 3. After taking the bottles, display the current password, and restart the level using that password. You will be able to take the same bottles once again until the maximum number (15) is accumulated. Note: Since only two hours of game play is allowed, spending excess time in this level may prevent successful completion of the game.
Skip to Last Level
Begin a new game, drop down two screens and run to the right to find a guard. Purposely lose to the guard. Press Select to obtain the current password when the "Press button to continue" text is displayed. Reset the game, select the continue option and enter that password. Game play will resume on level 20 with the previous amount of time and bottles.
