Most of the soundtracks are missing songs that are in the previous releases. As for poorer sound quality, I didn't come across that; it all sounds better to me, on the older CDs. I haven't listened to and compared the later stuff, though, so maybe there's something off with them.
I'm actually considering offering up the various songs that aren't included in the box set. Well, everything until and including
Castlevania (64). Beyond that, it's mostly more than just a few songs missing per soundtrack, so it'd be easier just to download the full soundtracks.
Edit:All right, guys (and gals). I compiled a rather odd assortment of
Castlevania tunes from official OSTs that didn't make it to the big box set. I ripped them all to VBR 320kbps MP3, all from CDs I own. One thing to note is my copy of the two-disc
Akumajo Dracula X CD released in '93 is a Son May bootleg. It sounds good, so I suspect the sound quality is the same as the official CD, but just in case it's not, I thought you should know.
Another thing is I'm not covering any post-
Castlevania (64) games, save for the
Symphony of the Night songs from the PSP version of the game (just to have that soundtrack complete). For the rest of the incomplete soundtracks, it's much simpler just to download (or, preferably, buy—monetarily support the things you enjoy, please) the full OSTs, since most of them are two-disc collections. For the
Akumajo Dracula X: Chi no Rondo soundtrack, I recommend the album
Akumajo Dracula X Chronicle Original Soundtrack (you can even download it from iTunes for $10), since the sound quality's improved over the original release from '93, and it includes the chiptunes plus cool bonuses.
Right. Here's the download link -

—From Akumajo Dracula Best—Simon's Quest (NES version) - The Silence of the Daylight
Simon's Quest (NES version) - Bloody Tears
Simon's Quest (NES version) - A Requiem
Dracula's Curse - Darkness and Tension: Dead Beat/Nightmare/Encounter
Dracula's Curse - Ending: Evergreen/Flash Back
Arrange Version - Distant Triumphant Return (Beginning) —From The Legend of the Devil's Castle—
Arrange Version - Bloody Tears —From Dracula II—
(These last two songs I actually ripped from the
Castlevania 20th Anniversary Deluxe Music Collection CD that came as a preorder bonus with
Portrait of Ruin, since I think the songs sound a little clearer on this CD than on
Akumajo Dracula Best. Also, the "arrange version" of "Bloody Tears" is nothing more than the version of the song from
Haunted Castle, but for completionist's sake [it has a different runtime and sounds different from the other CD versions], here it is.)
—From Akumajo Dracula Best 2—Belmont's Revenge - Castle
Belmont's Revenge - Journey to Chaos
Belmont's Revenge - Castle #2
Belmont's Revenge - Faith
—From Akumajo Dracula X—X68000 Arrange Version - Moon Fight
X68000 Arrange Version - Mother Earth
X68000 Arrange Version - File Load BGM
X68000 Arrange Version - Theme of Simon
—From Akumajo Dracula ~Gekka no Nocturne~ Original Game Soundtrack—
(Symphony of the Night OST)Prologue
I Am the Wind
—From Akumajo Dracula X Chronicle Original Soundtrack—Nocturne (English version)
Serenade of Sympathy
(These are the PSP
Symphony of the Night songs.)
—From Symphony of the Night PSX game CDs—Dracula's Castle (Remix)
Dracula's Castle (Remix - Japanese Intro)
(These are the "track 2" songs that are featured on the game discs. I own both the US and Japanese versions, which are different only in the intro—one in English, one in Japanese, and spoken by their respective voice actors for Alucard—but I felt it was fun to include both.)
—From Akumajo Dracula Apocalypse Original Game Soundtrack—
(Castlevania [64] OST bonus tracks)Melodies of Castlevania
Invisible Sorrow
A Night in Peace and Quiet
—And Lastly—I've included the entire
Oretachi Game Center: Akumajo Dracula Music CD album, since it features the
Haunted Castle music as it is in-game, with no post-production (unlike what's provided on
Akumajo Dracula Best Music Collections Box and
Konami Game Music Collection Vol.1).
43 tracks in all.
I hope this is useful for somebody. :p I've set up playlists on my iPod to have the "complete" soundtracks (complete insomuch as what's been released officially), and decided I wanted to share this with others who might not have the tunes. I actually think, in regards to the older games, that the music on the OST box set sounds better than the original CDs. It's probably just a slight mastering difference and nothing more—a simple levels boost—but it makes things just a little clearer and better, in my mind. Thus I've set up playlists for these games primarily using what comes in the box set, and filled in the blanks with the missing songs present on the old OSTs.
