Doo-doo doodoo doo-doo. That is the Game Boy rendition of the Rugrats main theme, only this time with more explosive poop jokes.

Placeholder Screens

Special Reward

Your new unsoiled diaper!

GameShark code 010511DE will start the game in a placeholder screen.


Rugrats The Movie SGB Unused GAMEWORLD.png

GameShark code 01060EDE will start the game in another placeholder screen. This screen only exists in the original monochrome version and was likely intended to display after completing a level. Pressing any button will not affect the screen.


Rugrats The Movie GBC Unused RGBer.png Rugrats The Movie SGB Unused RGBer.png Rugrats The Movie GBC Unused RGBer Signal.png Rugrats The Movie SGB Unused RGBer Signal.png

GameShark code 011511DE will start the game in a screen for testing the GBC palette settings. Unfortunately, you can't change the palette settings. Pressing the A button will bring you to a secondary screen where the game waits for a signal from a developer console.

Chapter Screen

Reading chapter 9, how are you doing?

GameShark code 011711DE starts the game in a chapter screen. There were originally going to be level chapters. A palette was only programmed for the monochrome version though the screen only exists in the GBC version, oddly.

Hidden Credits Screens

There are two credits screens present in the ROM that were cut for unknown reasons.

THQ Screen 1

Unused Super Game Boy Palette

A little contrasting, please! Rugrats for Virtual Boy!... No, not really.

The Game Genie code 330-47B-809 420-48B-F7B will load an unfinished palette that doesn't contrast too well.

Additional Planned Palettes

Located at 0x04C213, 0x04C223 are two PAL01 commands that are remnants of two additional planned palettes, which are black because the RGB values are all 00. Game Genie code 230-47B-809 420-48B-F7B will load the first unused palette, while 130-47B-809 420-48B-F7B will load the second and 330-47B-809 420-48B-F7B will load an unused PAL_SET command.

The listing starts at 0x04C213:


ICON_EN Oddity

For some reason, the game disables palette and controller settings then re-enables them a few commands later. This may hint further that additional palettes were planned. Game Genie code 004-E6B-2AF will leave palette and controller settings disabled.
