I think that's where I got my info from. (What magazine is that anyway?) Since the MSX2 version came out about a month after the Famicom Disk System one, I guess I filled in the gaps of what IGA said to mean, "Vampire Killer was in development first." But with the Konami website stating Vampire Killer is a remake or unique port, I'd be more willing to accept that information over what IGA said, especially since it sounds like he's talking about the MSX2 game having come out first in Japan, which isn't true; he must have gotten his facts mixed up, or else completely misunderstood the question.
