Disc 1 features arrangements of songs from Castlevania: Dracula X (aka Akumajo: Dracula XX (yes in Japan it was called XX), but also known as Castlevania V: Vampire's Kiss in Europe)
Anyways, to prove my point, here's a video from stage 5' where "Painting of the Phantom Ship" is the BGM.

So anyways, I added Castlevania: Dracula X to the Products and SNES to Systems since this game was for the SNES.
