Super Mario 3D World continues the brand new tradition of tacking "3D" on to the title of a completely unrelated Mario title. An enhanced Nintendo Switch version, titled Super Mario 3D World + Bowser's Fury, was released on February 12, 2021 worldwide.

Removed Test Stages


Located in /SystemData/MemorySystem.szs is a file named HeapSizeDefine.byml that defines heap sizes for levels. However, this does not apply to every single level, as there are 40 unused test stage strings located in this file. Many of the level names have staff names in them.

RPX File

The executable file, RedCarpet.rpx, also refers to a removed stage. The string exists beside the internal names of some used levels.

  • TestAndo07Stage
  • RouteDokanTourStage - World 6-1 - Clear Pipe Cruise.
  • KinopioBrigadeTentenStage - Captain Toad Goes Forth.
  • DownRiverStage - World 1-4 - Plessie's Plunging Falls.

Unused Music Tracks

To do:
Redc_bgm_Map01.my.32.dspadpcm.bfstm and STM_RC_BGM_PDOREMI_FAST.bfstm were also removed - are they used here?

All of the fully unused tracks here were removed from the Switch version's files.

Mario 'House' Music


This track's internal name is STM_BGM_TEST_BEATSYNC, suggesting it was for testing involving Beat Blocks. It's not referring to the "House" style of music, but maybe it refers to Toad Houses or Mystery Houses. The "02" in the filename suggests the stream was revised or had an alternate version(s) at some point.

World 2 Theme Duplicate

A standalone version of the World 2 theme. The game uses the copy stored in the second track of STM_RC_BGM_MAP01.bfstm. In the USA kiosk demo, it is no longer present.

Super Star Duplicate

A copy of the Super Star theme can be found in the music folder, which was presumably used as a test track. Super Mario 3D Land also has a duplicate copy of its Super Star theme.

Unused Portion of Banner Jingle

On recent versions of the Wii U system software, the Wii U Menu banner jingle only plays for about 8 seconds before the game starts automatically. Players with these later hardware revisions can hear the whole thing by removing the disc while the banner is displayed. The full track can also be heard on the soundtrack CD. And yes, the incorrect loop is part of the game.

Unused Object Settings

Switchboard Rails

The BlockRail objects used for the Switchboard platforms have two unused values for its color setting (RailColor). Red appears to be the default color of the models themselves, despite grey being the default parameter.

Red (1) Blue (2)

Grey (-1/0) is used as "0".

Unused Behaviors

To do:
  • Check if the Palm Tree/Block/Box behaviors are really unused, or just "inherited" code.
  • These behaviors may also exist in SM3DW + Bowser's Fury. If they do, add a note.

  • Palm Trees can be destroyed by Mega Mario.
  • Roulette Blocks can be destroyed by Mega Mario.
  • Pipes sometimes have their parameter set to be non-destroyable by Mega Mario, but these pipes are never used near Mega Mushrooms.
  • Cannon Boxes can be worn by Captain Toad.

Unused Graphics



ShadowTex can be found in various ObjectData texture archives. The text translates to "kage", which means "shadow".

SM3DW-Orange-Mario-Face.png SM3DW-Orange-Mario-Logo.png
An icon for an orange-colored Mario and a corresponding orange S logo, stored with the player icons. Their purpose is unknown, but could have been used for a "Super Guide" function, as featured in other Mario games such as New Super Mario Bros. U.

A hand icon, also stored with the player icons. Presumably, this was intended for a fifth player to control the "hand" (the one that can collect coins, hold enemies, etc.) separately with the GamePad, similar to New Super Mario Bros. U. It is also worth noting that unlike the in-game hand, which is a right hand, this icon depicts a left hand.

Internal Project Name

Super Mario 3D World's executable is internally referenced as RedCarpet. There is no other context to explain the rather... obscure project name, other than the prior game having an internal name of RedPepper. Other files in the game do refer to the project name, primarily abbreviated. The internal name is also reflected in the game's two-letter code "RD".

Filename Oddity

The castle music files are called *Castle01*, but there are no 00s or 02s.
