So very stubbly.
This page is rather stubbly and could use some expansion.
Are you a bad enough dude to rescue this article?
To do:
  • Look into the soundtrack/files and figure out which songs and sound effects are unused. With 600 or so of them, there are sure to be a few in that category.
  • These joystick icons. Are they unused?

Luigi's Mansion 3 is the third installment of the Luigi's Mansion franchise. Instead of taking place in a haunted mansion, however, this game takes place in a haunted hotel.

In this game, Luigi's friends are now permanent guests at Hellen Gravely's haunted hotel. King Boo dares Luigi to find them if he can.

Unused Maps


LM3-Sandbox Powerups.png

Sandbox_Powerups can be found in the root of the RomFS. Replacing the files of one of the ScreamPark minigames with the files in this allows you to load it, and while nothing displays, RenderDoc can be used with an emulator to get a view of what the map looks like, which it seems to be a test map for the game's powerups.

Unused Images

Colorful Shapes Icon

Kind of gives off 'old Windows icons' vibes, doesn't it?

This image can be found in RomFS/init.data. Although its exact use is unknown, it may have been a test image or a developer tool icon.

UV Map Test

UV MAP TEST UV MAP TEST: Electric Boogaloo

These two images can be found in RomFS/init.data. As the text in the images suggests, both images were used for UV Mapping on in-game models.

Red Coin


A graphic of a Red Coin can be found in RomFS/Scarescraper/Persistent.data. Red Coins were used in Scarescrapers in Luigi's Mansion: Dark Moon, but did not return for the third installment of the series.

UV Wrap Texture


This image can be found in the textures of RomFS/Hotel/Penthouse.data. It's unclear what exactly it is, but there is a possibility it was used for UV wrapping.

Scaling Texture

LM3 UnusedScaleTexture.png

An unused scaling texture in the file RomFS/Sandbox_Powerups/Floor01.data. It was most likely used to test how images would be displayed.

Developer Console

Is sucking the spirit of the deceased from their grave considered grave robbery?

Four bros, chillin' in a hot tub...
*Insert Super Smash Bros. Melee joke about breaking targets here*

In ScreamPark mode, selecting one of the three game modes will display a screenshot preview of its respective gamemode. However, for all three game mode screenshots, the game borders just barely crop out what appears to be developer console text in the top and bottom left corners.

Unused and Unheard Audio

Simple Luigi's Mansion Theme

There is a very simple version of the Luigi's Mansion theme in the audio. It seems to be a testing track that was possibly left in by accident.

ScareScraper Time Running Out

There is an unheard part of the ScareScraper time running out music. The unheard part starts at around 0:20 because at that time it cuts to a different track, and if you collect a timer item, it will stop the music.

Fishook Phase 3 Ending Segment

There is an unheard part of the Phase 3 music for the Fishook boss fight.
