Akumajou Dracula – Famicom Disk System 1st Playthrough

This is the Japanese Disk version of the first Castlevania game. There are many small changes between this and the English cartridge versions. Among them are switching sides of the disk, graphics that were later censored in the English version, some some changes to how power-ups drop, and a save system. Some games for the FDS had extra music channels, but I couldn't tell with this one. Anyone notice a difference in the music?
