Quick notes for people reading this thread: This is not about U.S. released titles; and not about the planned (but ultimately dropped) port of Castlevania II: Simon's Quest to the GBC (which would've been neat).

Did this series have a fourth installment? I've been hearing of a GBC version of Castlevania II: Belmont's Revenge (arr) for a while now, but haven't been able to track that down. Why? I recently got ahold of volumes 1-3 (would post link, but it doesn't seem to work for some reason...) and I wonder if I'm still missing something.

Link so everybody can see what I'm talking about:
