No Export for You: The original PC Engine version, thanks to the failure of the console's American counterpart, TurboGrafx-16. The game's inclusion in Dracula X Chronicles for the PSP and later its stand-alone re-release for the Wii Virtual Console would remedy this.
Woolseyism: Believe it or not, the audio for the cutscenes sound different between the PSP release and the original PC Engine version. This is most notable during the Annette's Fate cutscene where Shaft in the PC Engine version teleports into the chamber, while in the PSP release he walks in unnoticed. The music in each of rescue cutscenes are also different depending on the platform; the PC Engine music uses a clavicord for the scenes where Tera and Iris are rescued, carried over into Maria rescuing Annette, while the PSP music offers a mix of both flute and piano.
