The Haunted Mansion
Developer: High Voltage Software Publishers: TDK Mediactive (US), Take-Two Interactive (EU), Yuke's (JP) Platforms: GameCube, PlayStation 2, Xbox Released in JP: April 28, 2004 (PS2) Released in US: October 14, 2003 Released in EU: March 5, 2004 (PS2/Xbox) 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.

Level Select

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.

Platform	Button Combination
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.
