The Haunted Mansion (GameCube, PlayStation 2, Xbox)
|The Haunted Mansion|
High Voltage Software
This game has a hidden level select.
Thankfully based off the actual ride rather than the movie, The Haunted Mansion is a surprisingly decent Luigi's Mansion clone with some pretty good atmosphere.
During gameplay, hold Right on the D-Pad, then enter one of the below codes (depending on platform) to add a level select to the pause menu.
|GameCube||X, X, B, Y, Y, B, X, A|
|PlayStation 2||Circle, Circle, Square, Triangle, Triangle, Square, Circle, X|
|Xbox||B, B, X, Y, Y, X, B, A|
The way the level select is set up suggests that the rooms were to be visited in a different order as the Toy Room is normally visited after the Trophy Room, the Children's Room is visited after the Museum, and the Gallery is visited before the Observatory.
