Fixes a bug on the 4th Floor (The Great Stage) that caused the game to freeze permanently during or immediately after the Amadeus Wolfgeist piano boss battle.

You should only install updates for a game you legally own.

Most people played Luigi’s Mansion 3 the normal way. They bought the cartridge, downloaded the official patches, and enjoyed the polished, whimsical horror of Mario’s terrified brother. But the "repack" community knew better. They knew that early scene releases were messy. They knew that specific updates fixed specific lighting bugs in the Boilerworks or physics glitches in the Unnatural History Museum.

PC emulators treat the base game and updates as separate legal files to prevent code corruption. Open your emulator of choice.

: Five new types of rare ghosts were added to the ScareScraper mode.
