Luigi wins a mansion in a contest and his brother, Mario, goes missing there. It is your goal to search the haunted mansion to figure out where he is. Your weapons to protect you are a flashlight and the Poltergust 3000, a ghost vacuum. Capturing ghosts and collecting keys helps you progress in your quest to find Mario.

The author, solarplex, utilizes out-of-bounds glitches to skip 19 of the 23 Portrait Ghosts and all of the Boos (except King Boo), beating the whole game in around 10 minutes with TAS timing, or 8:28:52 with RTA timing.

This run plays the Hidden Mansion, a mode unlocked after beating the game once that increases the power of the Poltergust and allows skipping some cutscenes, to make the run more entertaining. We do not normally accept runs that start from dirty SRAM; see the rules for more details.
