Enter "?TJL BDFW BFGV JVVB" as a password. Then the game will begin on level one. Now pause the game to access a new "Features" menu that allows level selection, invulnerability, map mode, health boost, and weapons/ammunition. You can also access the "warp to fun" levels 25, 26, and 27. Once enabled, the health boost and weapons/ammunition options may not be disabled. The invulnerability option will be disabled on level 32. Once enabled, the features menu will appear when any saved game is paused until the Nintendo 64 is powered off or reset.
Destroy all the barrels on Level 1 to access Level 32. The warp is in a secret room behind the starting location of the level. Save the first barrel to be destroyed last.
