List of Mario & Luigi: Partners in Time pre-release and unused content

This is a list of pre-release and unused content for the game Mario & Luigi: Partners in Time.

Localization preview

 * One scene featured Luigi being hit on the head by a washtub falling from the celling, a common gag in Japanese slapstick. Members of Nintendo's North American localization team, Treehouse, explained that the joke would not be familiar to American audience, and thus the washtub was changed to a bucket in the final game.

Press kit material

 * The game was originally named Mario & Luigi 2.
 * An early screenshot depicts Mario, Luigi, and their baby selves fighting two red shoe-clad Blooper foes (called Scoot Bloops) in the Vim Factory. Unfinished code for the Scoot Bloops remain the final build of the game (see below).
 * Another screenshot shows the brothers using a Mix Flower on two Boo Guys in Hollijolli Village, while Boo Guys were not present in this area in the final game and Mix Flowers do not look or act this way in the final game.
 * There are also screenshots of the four brothers using what appears to be a purple Spiny Shell as a Bros. Item. This item would act like a Koopa Shell, but would be hammered instead of kicked.
 * Baby Mario's initial artwork erroneously depicted him as having red shoes rather than his normal blue ones, although his shoe coloration would appear to have always been consistent throughout all of the actual game's programming.

Instruction manual

 * In page 27 of the instruction booklet there are two images of Mario leveling up, here instead of having "stache" he has "hige" (a Japanese word for mustache).

Debug menu & unused room
A debug menu can be accessed using the Action Replay code 94000130-fffa0000 + 1205e768-0000000c + 1205ef50-0000000c + d2000000-00000000. While save data is being loaded, the player must hold  + . One of the selectable rooms will have an unused Yoshi Egg, and an unused chat bubble with a heart bubble.

Scoot Bloop
An enemy name in the ROM, Scoot Bloop, was unused. In all versions of the game excluding the Spanish release and South Korean release, it has been translated. Sprites of this "Scoot Bloop" have recently been ripped from the game and its unused data was discovered. Apparently, Scoot Bloops attacked by ramming into the player. Due to the data being unfinished, battling them in-game and letting them attack will cause a Scoot Bloop to attack and not return, or freeze the game.

Miscellaneous
Although the Japanese version of this game only gives players the option to play in Japanese, it actually contains at least a partial script in English, French, German, Italian, and Spanish as well. These often differ from what would eventually be released in the European version of the game. A list of changes can be found below.
