Mario & Luigi: Bowser's Inside Story/Unused Field Maps
This is a sub-page of Mario & Luigi: Bowser's Inside Story.
This page features all unused field maps in the game. Field maps include 3d rooms, 2d rooms, and maps. Using the Action Replay codes below (only for the USA!), we can enter any of these rooms regardless of when we are inside or outside of Bowser, playing as Bowser or the Bros. To use them, you will have to combine use of multiple of them. Some correspond to the screen, others to the characters. For instance, if I were to enter one of these rooms as the Bros. and outside of Bowser, I would be using the Bros. code and the top screen code. The music for the room will only play when you use a loading zone that by default, takes you to a room with different music. The codes below contain "XXXX". Replace all of the occurrences with the desired room ID. To use these, hold the L button and walk into a loading zone.

Room 0x0000
A room in Plack beach. The room doesn't have any loading zones however, and there is a Bowser sprite in the center of the room, which can be controlled by entering the room as Bowser. There's also a non-functional air pipe near the top. The final version of this room is impossible to enter with Bowser without cheats, hence why this room typically loads when something non-intentional happens (e.g. going to the final boss with the Bros., rooms without a map, entering Bowser during the prologue in Peach's Castle..). Interestingly, when hammering the Bowser sprite, the screen flashes black and the camera moves to the center of the room, where Bowser is. Also, the room plays the "Shock!" music.
Room 0x0001
Same as x0000, except it plays the Plack Beach music, and the Bowser and air pipe sprite aren't present.
Room 0x0002
The debug room. Entering this room facing north will softlock, however entering south will not.
Room 0x0003
An unused room featuring possibly early Dimble Wood graphics and a blue pipe in the middle. The pads are incorrectly colored however, and a duplicate can be found north of the pipe. The pipe can be used however, both screens will turn black. However, you can still move interestingly, although you can't see anything. Opening the map directly causes the game to crash, however opening it from the Star menu doesn't. After exiting the Star menu, the game just softlocks, the screen will still be black. The room also plays the "Shock!" music. There is a non-functional loading zone to the right, does the same thing as the pipe. If the room is entered with Bowser, you can make the screens show again by switching to the Bros. then back to Bowser.
Room 0x0004
A large testing room for Bowser. Entering this room with him is a bit difficult however.. The room also has a black outline.
Room 0x0007
An unused room in the Pump Works, has a few very tall platforms and no objects or exits. There is collision however, and it does place you on the correct map (although it shows you're at the top left corner).
Room 0x004B
A room in Dimble Wood featuring the Tower of Yikk, suggesting it was originally meant to be found there instead of Blubble Lake. It has no collision, exits, or music. Interestingly, the tower's entrance is facing west, instead of south like it is in the final.
Room 0x01DD
A room that represents some test rooms inside of Peach's Castle. It has very simple graphics, and loads the interior of Peach's Castle on the map (which may not show until you use a loading zone in that area). It also plays the music for the interior of Peach's Castle. The top exit takes you to room x01DF, however the bottom exit takes you to room x01D7, which is used in the final. The bottom exit requires that you face north when entering it however.
Room 0x01DE
Another testing room inside of Peach's Castle. It has a wall in the middle which we can't pass, some raised platforms that are blue, and a hole in the ground that has hidden walls around it. The bottom exit takes you to room x01D7 as well, but you must be facing north to enter it. The top exit takes you to room x01E0.
Room 0x01DF
Yet another testing room inside of Peach's Castle. It features 2 pipes which are not functional, the bottom exit takes you back to room x01DD. The top exit takes you to room x01D7 as well, however you must be facing south to enter it.
Room 0x01E0
Another testing room inside of Peach's Castle. It has 2 pipes which are not functional, similar to room x01DF except they are on the other side. The bottom exit takes you back to room x01DE, and interestingly there are no other exits in this room.
Room 0x01EE
An unused map of Dimble Wood, showcasing the area around the giga-carrot. This map and the other unused Dimble Wood maps don't actually have the stars on areas that haven't been explored yet.
Room 0x01EF
Another unused map of Dimble Wood, showcasing the part in the prologue and the exit to Blubble Lake. In the final, the exit takes a turn to go up, however in this map it keeps going to the left. More interestingly, on the right hand side you can see a room with a slope in the entrance. That area depicts the unused room x004B. In the final, the used room in that location is room x004A, which doesn't have a slope.
Room 0x01F0
Another unused map of Dimble Wood, showcasing the part where Mario is stolen by Sockups.
Room 0x01FF and Room 0x0200
A room depicting the Tunnel near Bowser's Path. Both room x01FF and x0200 have no collision, no exits and are unused. The only difference between the two is that room x0200 spawns rocks on the path which then immediately break for some reason. They also shake the screen a lot.
