In its beta E3 2001 version, Luigi’s Mansion featured different ghosts than the final version. The 3 main ghosts (Orange, Pink, and Blue) were very different looking than their present day forms. The Orange ghost used to be a pink colored ghost featuring smaller eyes and mouth. The tall and thin pink ghost was once an orange lanky ghost with a huge nose. The blue ghost was originally a purplish colored ghost with smaller eyes and mouth. There was also another ghost that was scrapped from the final. It was colored dark purple, had a similar look to the pink beta ghost, and was only found in the hallways of the Mansion. Of what the ghost did was come up behind Luigi and scream; causing Luigi to yell in fear and fall to the ground. This would cause 50 HP to be drained from Luigi’s health and temporarily shrink his total HP to 50 as well. If the ghost still exists, it would have the same behavior as a ReDead.
In very early screenshots (all being the E3 version), there were shots of a timer in the Game Boy Horror, possibly hinting that the game was either going to have a challenge mode or a time limit, but was scrapped in the final version. It is said that if Luigi did not save Mario within the 24 hours he had, the mansion, along with mario, would vanish. In other builds, the Gameboy Horror also feature a Gameboy Camera-like effect, so it showed everything it could “see”. It is suspected that the Gameboy Horror had at first the time keeping function, and then the Gameboy Camera-like mode, and the onto a different version of the final’s GBH. The near final build had more of a cartoony icon set, while the final build has the more realistic icon set.
The Poltergust 3000 once featured a “heat meter”, showing of how hot it would get from sucking objects and ghosts up. Its gauge went from a level of 1 to 10. Once it got to 10, the Poltergust 3000 would burst into flames, and cause Luigi to collapse onto the floor, also having Luigi lose some of his HP. On the side note, the Poltergust 3000 was more squarish compared to the final’s version.
Other differences include slight changes in room designs, a beta coin meter, and many other objects. – [info from Wikipedia]
The ending screen would probably unlock to your file a “congratulations” image, or probably just an image for the ending, such as a picture in the wall. Three unused different looking sprites were found by Gabrielwoj, as can see below:
“luigi_b.bti_color/alpha”, probably with Bad ending, with low money. (B = Bad)
“luigi_g.bti_color/alpha”, probably with medium ending, with a good quantity of money. (G = Great)
“luigi_V.bti_color/alpha”, probably with perfect ending, with all the money caught. (V = Victory)
Thanks to SteamingBullet, Matthew Burke and Gabrielwoj for the contribution!
Miyamoto recently spoked about the Nintendo 3DS system, and said that the Nintendo Gamecube was capable of playin stereoscopic 3D video. He said too that they made a compatible version from Luigi’s mansion that with an accessory is able to display in special LCD TVs the game in 3D.
According to a issue in nintendo power,there was going to be a hidden boss ghost that was a generic austrailian hunter guy,and had dialogue that was on the lines of saying he wanted to Kill you and mount your head on the wall. He shot his rifle at you as you ran around the Safari Room.
