Pokémon Mystery Dungeon: Explorers of Time & Darkness
Pokémon Super Mystery Dungeon
This song works well when used in any indoor level. A castle, cave, ghost house, etc. (probably NOT for a switch palace)
UPDATE: Tacked on $F4 $02 to make the entire thing sound much better than before. I also changed a few things here and there a while back, but can't remember what exactly (it was probably ADSR or something).
