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.

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: 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.

Cheats#

• 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.

Invisible Triggers#

Found in the Hub World, are a few triggers that allow the player to skip parts of the game. These are out-of-bounds and the player will require to use the superjump move in order to access these triggers.

Ending Cutscene Trigger#

Watch on YouTubeA debug trigger, meant for the ending cutscene after you beat Earthworm Kim, can be found on top of the hub world.

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.

Unused Intelligence Text#

There is some unused text relating to the intelligence system used to unlock levels.

Indication of a Fifth Hub#

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

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.

Localization Placeholder#

The US version only runs in English, but using GameShark code 800D2795 000? (where "?" is one of the below) to force the game to use a different language reveals that the game has placeholder text for the other languages.

0 - English
1 - French
2 - German
3 - Spanish
4 - Italian
5 - Jîbber-Jabber

Notably, the Jîbber-Jabber "language" only accessible in the European version is present and fully functional in the US game as well.

Oddity#

In the Windows version, Track_13 is duplicated as Track_14 in the game files.

Regional Differences#

Jîbber-Jabber#

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 Jîbber-Jabber, which seems to be an intentionally-bad English translation.

English	Jîbber-Jabber

Platform Differences#

To do: Save selection icons are different as well

The game was released on PC seven months after its N64 release, with some minor tweaks here and there.

Resolution Changes#

The PC version runs in 640×480, while the N64 version runs in its native resolution 320×237.

Title Screen#

The game's title screen is different on PC, removing the in-game demos and adding some options to the menu.

PC	N64

In-Game#

The PC version's sprites are pretty much cleaned up and some are changed, the textures are also in a higher resolution and are more detailed.

PC	N64

Music Differences#

The PC version's music is in a much higher quality than the N64 version. The soundtrack, while similar in the PC version, adds more tracks. Some songs were also trimmed down.

Falling#

The PC version has a different intro, and is much shorter than the N64 Version.

Death#

The PC version is two semitones lower and is a bit slower than the N64 Version.

Jumping Height#

The PC version adds more height to Jim's jump. As a side effect, this breaks the level design in various places.
