The Japanese version of the game is called "悪魔城ドラキュラＸＸ Akumajō Dorakyura Daburu Ekkusu" - which in English literally translates to "Devil's Castle Dracula Double X". The American version, however, is simply called "Castlevania: Dracula X". Likewise, the Australian & European versions were renamed to "Castlevania: Vampire's Kiss".

There are also several differences between the titles screens of the three games. The Australian/European version does not have blood on its title screen. The Japanese version also uses two religious crosses in its "Double X" title, rather than a single red X used by the American version. The "PASS WORD" option is also spelled incorrectly in the Japanese version, but was later corrected as "PASSWORD" in the International version.

In the Australian/European & Japanese versions, the boomerang cross weapon looks like a religious cross, but was replaced with a regular X-shaped cross in the International version. This was likely done to avoid any religious complaints.
