Maniac Mansion is a point-and-click graphic adventure game by LucasArts in 1987. It was ported into the Nintendo Entertainment System by Jaleco in 1991.

This game is about the Edison family: Dr. Fred, a mad scientist, Nurse Edna, the wife of Fred, and their son Weird Ed.

Maniac Mansion for the Nintendo Entertainment System was heavily censored prior to its release. This hack seeks to replace as much censored content as possible from the original Commodore 64 version.

The following changes are included:

Graphics and Gameplay

- The skeleton is added to the dungeon and the dungeon layout is updated to match the original (never before seen in the NES version)
- The Kill Thrill arcade game is restored (never before seen in the NES version), with optional patch for Douglas Crockford's Muff Diver
- The pennant is added in Weird Ed's room (only seen in a previous hack)
- The surplus body parts are now in Cousin Ted's room (never before seen in the NES version)
- The poster and calendar are back in Cousin Ted's room (never before seen in the NES version), with optional graphics and text patch
- The Disco Sucks poster is restored in Green Tentacle's room
- The shower text, for a good time, is restored
- The statue in the hallway is restored
- Green Tentacle kills the player after hearing the tentacle mating call recording (never before seen in the NES version)

Text Changes

- Edna: Dungeon dialog (should have tied you to my bed etc.)
- Edna: Phone dialog (heavy breathing etc.)
- Ed: He hasn't eaten in 5 years
- Dr. Fred: getting your pretty brains sucked out.
- Dr. Fred: The meteor is going to be pissed!
- Dr. Fred: You're going to piss off the meteor.
- Dr. Fred: Don't be a smart ass!
- Green Tentacle: think I'll kill myself!
- Purple Tentacle: Kill him.
- Meteor: Dr. Fred, release the women, all the women.
- Meteor: Prepare to die!
- Player: Damn! broke it! (for Ed's piggy bank)
- Calendar text in Ted's room
- Brain diagram's chewy caramel center
- SCUMM System and NES SCUMM version in credits

(Note that some of the above may be slightly modified here since romhacking.net does not accept personal pronouns in the description.)
