Debug mode:
Press C-Up, Up, C-Left, Right, C-Down, Down, C-Right, R, A, B when "Press Start" appears at the opening screen. A sound will confirm correct code entry. Use controller two to select the debug options. Press Start to cycle through the options, such as "Cheats", "Level Select", and more.

When you enter the code on the title screen and hear the horse, the Cheats Menu will be available but will have no cheats active (unless you they were previously activated or earned). Once you start or load a game/level, text will appear in the upper/left hand corner of the screen. Use controller two to control the debug options. Pressing Start cycles through the various lists of options. Use the buttons noted below to change certain values. Note: Debug mode does not save on the memory pak like the other cheats.

Multi-player debug mode:
Enable the "Debug mode" code as usual, then start a two or three player multi-player match. You can use the unused controller to control the debug menu. The best use for this is to use the warp to play the regular game with multiple players. . You can complete the game as normal or fight each other. When you die, you will just reappear because you are in a Dukematch.

Glitch: Talking guns:
On Level 2, The Streets, collect a powerful gun such as the grenade launcher, or something that destroys a large area. Enter the Dukeburger Restaurant. Equip your powerful weapon and if you want and kill the army man on the landing of the steps. Move into the corner of the landing very slowly and look into the top room until both army men are in your view. Shoot a few grenades at the army men until both are dead -- pick up their guns. Walk into the room -- as if the army men were still there, Duke will start to talk to them, and the guns will respond to Duke. Note: This also creates a hole in the wall that can be entered to reach a hidden Babe
