Yes, I chose to remove the X in the title screen.
I chose to do this in order to keep continuity between Rondo of Blood and
Castlevania: Symphony of the Night's English localization (Symphony of the Night is a sequel to Rondo of Blood). In Japanese Both games had an X in the title.
Akumajō Dracula X: Chi no Rondo
Akumajō Dracula X: Gekka no Yasōkyoku
The X was removed in Symphony of the Night when brought over seas, so it makes since to also remove it in Rondo of Blood as well.
Besides, Konami has already given Rondo of Blood an official English name in the states, which is
Castlevania: Rondo of Blood, and if we where keep the X it would just cause unnecessary confusion.
Sure, the X was neat, but I think keeping continuity is more important.
