Deka Voice

Post by RosenkreutzXIII »

Hello there, recently I was ripping a Japanese exclusive PS2 game titled "Deka Voice." It's an interesting alternate 1920s crime-drama developed by Acquire that utilized the PS2 headset, Acquire also developed another microphone based game some of you may have heard of before titled "Lifeline" or "Operator's Side" as it's known in Japan.

Originally I was using a fairly simple program titled "PSound" which seemed to work fine as it ripped the BGM, Cutscene and Dialouge files and such with no apparent issue. Recently however, I noticed while watching some videos of the game on Nicovideo that there's a jukebox in a particular stage that plays music from the game in it. In the jukebox there's a longer more detailed version of a vocal song which otherwise only seems to plays in a cutscene audio file and thus has dialogue and SFX in it. This got me thinking that there might be more audio files buried elsewhere as I noticed that in addition to the non-cutscene version of that particular vocal song, that the main menu theme was no where to be found in the files I ripped either.

Thus, I was curious if anyone could try taking a look and see if there are more audio files or not. Below I've provided what should be all the files from the disc.

ADX folder: it's the AFS format supported by http://aluigi.org/bms/afs.bms and these archives contain ADX files which are CRI middleware files
DUMMY.DAY: another AFS archive like those in the ADX folder
DATA.VOL: it's a very simple format http://aluigi.org/bms/deka_voice.bms

There are no other files or archives.

Thanks a bunch, seems the missing audio files I was looking for where also in the BGM files I extracted with PSound, but for whatever reason PSound was unable to extract all of them like QuickBMS was.
