Final Battle - Master of Darkness (SMS)
Final Battle is the boss background music for when you fight Dracula in Master of Darkness.
Vampire: Master of Darkness (GG)
The song is track 13 in the SGC file and rendered on the Game Gear's SN76489 chip.
Master of Darkness (SMS)
Since the Master System / Mark III use the same audio chip as the Game Gear (SN76489), the music sounds identical on each.
The Nintendo Wii port is just an emulated version of the game, so it sounds identical.
