Touhou Meltdown BGM

Replaces the meltdown music with 東方核融合 (Nuclear Fusion) from Touhou 11: Subterranean Animism when the Apparatus is pulled.

Features

• Harmony patch on LungProp.EquipItem — only triggers when a docked apparatus is pulled
• Does NOT trigger on maps where apparatus is already undocked/unpowered
• Fades in music over 1 second
• Suppresses FacilityMeltdown's default music
• Fades out when ship is leaving
• Stops on return to main menu
• Works independently — does not require FacilityMeltdown (but works alongside it)

Installation

Place the TouhouMeltdownBGM folder in your BepInEx/plugins/ directory.

Config

• Volume (0.0 - 1.0): Adjustable in config file
