So very stubbly.
This page is rather stubbly and could use some expansion.
Are you a bad enough dude to rescue this article?

Earthworm Jim 3D is the 3rd (get it?) entry in the series and is notorious for being lackluster. Help Earthworm Jim as he tries to save his mind!

Debug Menu


The below GameShark code will replace the in-game pause menu with a debug menu that allows for various debugging features and cheats to be toggled.

Version GameShark code
USA 81084DC0 1440
Europe 81084E5C 1440

The same pointer to replace the menu is located at 859C0 in the ROM.

You may need to reset the emulator/console in order to make it work. It is similar to debug menus found in Tom and Jerry in Fists of Furry and The Powerpuff Girls: Chemical X-Traction.

Alternately, you can apply the below code then when at the Press Start Button screen, press C-Up, C-Right, C-Down, C-Left, C-Up to enable debug mode which replaces the pause menu with the debug menu.

Level Menus

A standard level select. This one appears to be broken, however, as there's only one option, for the hub world.

Game Progress

View the progress of the currently active file.

Tools Menu

  • Audio Tools - Contains on/off toggles for the game's music, SFX, and digital signal processors.
  • Music Volumes - Presumably would adjust the volumes of all of the game's music tracks, but doesn't appear to do anything at first sight. Try adjusting any of them after changing to one of the DSP options in-game.
  • Video Tools - A simple menu for adjusting gamma, aliasing and dithering.
  • Debug Tools:
    • Realcam - Enables a different (unused?) camera mode controlled by the C-buttons.
    • Timer - Displays some colourful bars on-screen.
    • FPS - Triggers a simple frames per second display.
    • Heap Monitor - Shows several statistics for the game's resources.
    • Compensate - Unlocks the frames (game still shows 60FPS but everything is faster).
  • QA Tools:
    • Freezeframe - Freezes the game on the current frame.
    • Coords - Shows the player's coordinates.


  • Health/Lives/Ammo/Guns - Switches infinite health, lives, ammo, and guns, duh.
  • 20 Extra Marbles - Self-explanatory.
  • Collect an Udder - Ditto.
  • Brain Cut-scene - View said cutscene.
  • Kill Boss - Kills the boss, if there's one on-screen. Freezes the game otherwise.

The text for the debug menu, as well as some status and error messages, can be found at C4090 in the ROM.

Unused Text

Unused Level Names

Each map has a short and long variant of its name, for example "Boogie Nights" is the short version for "Boogie Nights of the Living Dead". There is an unused copy of the Poultrygeist Too names (The real names referenced by the game are stored elsewhere) which states that the long version of "Poultrygeist Too" is "Poultrygeist II: They're Back", which is stored at 0x800C1B9C in RAM.

0x800C1ABC Aggression Hub Unused name in menus for Memory Hub.
0x800C1AB0 Agg Boss Most likely placeholder for Psycrow fight.
0x800C1AA0 Hamburger Hill Placement indicates that it's the long name for "Agg Boss", name indicates old name for Fatty Roswell fight.
0x800C1A70 Final Boss Like Aggression Hub, hidden name for Earthworm Kim Fight for the menu.

Indication of a Fifth Hub

In the game's memory, there's some text relating to Objects in certain categories.

Address String Notes
0x800C0080 Aggression Objects "Aggression" was the old name for the Memory Hub.
0x800C0094 Brain Objects -

Unused Code

Normally at run-time, a call is made to function 0x80026858 which disables all debug cheats. However, at 0x80026820 is a routine that enables all of the debug cheats at run-time. This enables the debug cheats: Health, Lives, Ammo and Guns. It also activates two other things, however it's not clear what they are or if the game even uses them anymore. Apply the below code to re-enable this call at run-time to activate the cheats.

Regional Differences


In addition to the European version containing options to display the text in French, German, Spanish, and Italian, it also contains an option for a "language" called "Jibber-Jabber", which seems to be either an intentionally bad English translation or simply the localisation team having some fun.
