Super Castlevania IV Uncensored is a modified version of Super Castlevania IV, likely fan-made, removing or altering content deemed objectionable. The original game is known for its generally mild content, and this suggests removing religious or cultural references. Gameplay should be the same as the original title with only minor differences. The creation of this modified version is independent of the original developer, Konami.
