Vampire Killer SCC

Who hasn't enjoyed Konami's MSX2 game Vampire Killer, it's a classic. The 1986 game, has an amazing soundtrack with tunes worthy of whistling throughout the day. Published before Konami gave us SCC music, Vampire Killer had to do with PSG. While it rocks on 3 channels, everyone was curious how it would sound if it came with SCC. Over 30 years later, the soundtrack has been re-written to fit the answer. Vampire Killer on SCC steroids.

Jan van Valburg, known for The Great Gianna Sisters among others, has picked up the trade again. He has secretly been working on making Vampire Killer with SCC music. All the songs have been re-arranged with additional chords and melodies to take advantage of the extra SCC channels.

The new SCC music has been written in an MML-style language and then compiled into the Konami music format and written into the ROM. He had to reverse-engineer the Konami SCC music player to get this working. The source code has been made available through a mercurial repository on Bitbucket, and he hopes to release more information about the reverse engineering process and his custom tools in the future.

This Vampire Killer upgrade has been released as an IPS patch to the ROM version, or you can manually patch it using the Python patching script in the source repository. To play this on a real MSX you will need either 256K RAM, or a flash cartridge. Now, go nod your head while shouting "this rocks!!" \m/

This SCC patch already has FRS' TurboFix patch built in. Unfortunately it's not compatible with the Castlevania patch though, because it's based on a different version of the Vampire Killer ROM.

Not sure to what extent you're serious or not ;-) But to remove further doubts, according to what I've learned:

a) 悪魔城ドラキュラ Akumajō Dorakyura FDS was release *before* Akumajō Dorakyura MSX (Sep 26 & Oct 30 1986 respectively). For Europe, I believe, VK MSX (1987) came before CV NES (Dec 1988), not sure if NA's NES release (May 1987) did or did not predate EU VK release;
b) technically MSX never knew 'Castlevania', being dubbed Vampire Killer (in the West).

(Sorry for being a bit of a nitpick/wise-ass perhaps )

I will dedicate my next post to JH

-edit: interesting: on the back of the EU release there's the heading Dracula's Satanic Castle.
I see 悪魔城ドラキュラ Akumajō Dorakyura often being translated as Devil's Castle Dracula (bit weird IMO) I'd rather translate it as Demon(ic) Castle Dracula myself, but perhaps the proper translation would indeed be Dracula's Satanic Castle?

And the arcade version was called Haunted Castle. They sure tried a bunch of things before settling on a name for the west .

Quote:

It's fascinating to see how the [sound] file format changed from game to game, what all the different commands are that the music composers had access to, and how they used it to make their music. I intend to release more information about this in the future, and I also will release the tools I wrote to decompile Konami music.

Looking forward to that, seems like an interesting story!

@Ren: I meant that it was was the one TRUE first version of the series; especially now. (was actually jokingly not acknowledging the NES/ Famicom game even though it is good, but because I prefer the MSX version)

Yes, it is widely known that the FDS version is released before the Japanese msx version. But the MSX version was in development first. So the series originated on MSX; the Famicom team played catch up some time after start of development, then they both developed in tandem and then just happened to finish/ release first. And that is not surprising seeing levels and mechanics are greatly simplified.
I was not being literal about it being called Castlevania; at the time of the FDS and Famicom versions Castlevania didn't exist either since the name was thought up much later for the NES release. Kenji Hiraoka (founding director of Konami UK) was the one who came up with the the name "Vampire Killer".

15-01-2018, 21:32

@Randam Interesting. Now you mention it, I vaguely recall having heard about which/what was in development first. Where did you read/hear/get that?

If they indeed started on MSX, okay, that outweighs first publishing date ;-)

The story does sound familiar to me, but I'm not sure myself that was about VK :-)

If those are the facts, and seeing the number of CV fans, this must be mentioned somewhere in an article or interview out there? (And/or someone else here that is able to confirm this? )

Por Randam

Huh, Hideo wasn't a director for this series in the beginning?

JK: many of these stories are similar since often stuff got done simultaneously. Snatcher also got done mostly simultaneously with the PC88 version but in that case the PC88 version was the leading one and the one that got released the first.

You know, before I forget, as everything that can be said about this (mainly that it's amazing) has already been done so, I would like to point out what gives this like 100 extra bonus points for me -
The fact that the re-arrangements actually 'correct' the soundtrack in that it introduces the things that would give the NES version an edge over the MSX one.
Such as re-instating the introduction in "Wicked Child" and the more elaborate melody part in "Vampire Killer", which were dearly missed in the MSX version soundtrack.

18-01-2018, 21:28

Thanks man I'm really pleased that you noticed those things.
Before I arranged each song I listened to the NES version, and any other versions I could find.
I wanted the music to be different than the original MSX version, but I also wanted to stay true to how Konami intended it to sound.
Thanks for posting that.

Could this mean that the MSX version was made before than the NES version?

I always thought that the MSX version was finished before, but releasing on cartridge (production time) takes more time than on disk.

There is a little flaw in the sound routine. Bits 7 and 6 of register 7 are not always well positioned. This can cause problems with joystick on some configurations. Bit 7 must always be 1 and bit 6 to 0.

If you notice on the Youtube Video the SCC volumen change every time I trigger a SFX(PSG). That not happen with Turbo R this test was done
using MFRSCC+SD, SNATCHER SCC (256KB SRAM) , ESE-RAM(512KB SRAM) the negative thing at least for me the PSG output from Turbo R was little bit lower than SONY HB-F1XDJ.

In summary internal Mixer from some MSX Computers are different so not STANDARD INSIDE. ;(
