Luigi's Mansion 3

Bugs

Unused Maps#

Sandbox_Powerups#

Present in the root of the RomFS. Replacing the files of one of the ScreamPark minigames with the files in this will allow you to load it. While nothing displays, RenderDoc can be used with an emulator to get a view of what the map looks like, which suggests it's a test map for the game's powerups.

Unused Graphics#

Colorful Shapes Icon#

Present 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#

Present in RomFS/init.data. As the text in the images suggests, these were used for UV mapping on in-game models.

Red Coin#

Present in RomFS/Scarescraper/Persistent.data. Red Coins were used in Luigi's Mansion: Dark Moon, but did not return in this game.

UV Wrap Texture?#

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#

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 Screenshots#

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-left and bottom-left corners.

Unused and Unheard Audio#

Luigi's Mansion Theme#

A very simple version of the Luigi's Mansion theme, likely a test track.

ScareScraper Time Running Out#

The ScareScraper "time running out" music is only heard for about 20 seconds, with the game cutting to a different track afterward and stopping it if you collect a timer item, but the track is actually about 36 seconds.

Fishook Phase 3 Ending Segment#

An unheard part of the Phase 3 music from the Fishook boss fight.

Level Select Menu#

Convert the NSO into an ELF in the 1.0.0 release of the game, go to 0x13B3648 and replace 2F456E67696E652F with 2F55736572000000. Next, using atmosphere add ini/buildinfo.ini with the string: "UseTestLevels=true" If done correctly, the user will be faced with a screen of folders upon boot, which each correspond to a level/floor. This menu can access test levels too. As seen in this video by Skawo. https://www.youtube.com/watch?v=IYn5mL_HYlI
