Castlevania: Harmony of Dissonance – Definitive Edition is a combination of some other great hacks for the original game with some edits by N.Dpendent.
The hack contains the following improvements:
-Character outline removed
-Speed-effect is not blue but same as character colors.
-Menu is red and so are textboxes
-Damage makes you flash red and not green
-Death is gray instead of pink.
-Other minor color changes.
