ROM Hack [Help] How decrypt audio files from 3DS Roms?

Link-59 · Jan 16, 2016

Hello !
Right now, I try to extract the music from the 3DS Roms. I have already managed to The Legend of Zelda Tri Force Heroes and Animal Crossing Happy Home Designer, but for other games such as The Legend of Zelda Ocarina of Time 3D, there are only files ".bcsar". So I extract these files with BCSAR Extractor. This creates 4 folders. 3 empty folders "[CSAR]" ; "[INFO]" and "[STRG]". The last folder, "[FILE]", contains other types of files: ".CSEQ" ; ".CBNK" ; ".CWAR" and ".CGRP".
For ".CSEQ" and ".CWAR" files, I use 3DS Audio Ripper. For ".CWAR" files, I still get little noises, sounds, but no music.
But for ".CSEQ" this does is create a "cseq" folder that contains only the same file size as ".CSEQ" precedent and called "0x0.CSEQ" ; So it does not do me when to use this file ...
How to convert ".CSEQ" files into a readable file? And files ".CBNK" and ".CGRP" ??
Thank you in advance to people who can help me!

.CSEQ can be converted into midis.
.CWAR are wave archives, they contain .CWAV files. They're mostly used for sound effects and instruments for the .CSEQs
I've managed to extract both formats, but the other files, I don't know fully.

oh God midis are horrible...
But how do I play cwavs?

Also I'm don't know shit about this but I remember something about "sound banks" from ripping sfx from n64 games. Maybe it's some kind of "sound bank". Then again I don't even know what a sound bank is

What? If you're talking about the actual sound output, that's the Microsoft GS Wavetable Synth.
Midis are just files which say "This is how these notes are arranged, which instrument bank is assigned to is, what its modules are and BPM"
Different wavetables have, well, different wavetables; different instrument banks. It's why midis made on Macs won't sound the same when copied over, because say Mac's #something violin may be MSGSWVS's #75 Recorder.

VGMStream or something, foobar2000 I've heard. Can't remember what people were buzzing about.

Is it exported to a .mid? That's what I was wondering

Yes.

Hmm interesting. I guess it's always cool to be able to switch the instruments around. Someone could make some really cool remixes with that

Depends on what the .cseq files actually contain. In XY/ORAS, they're mostly used for sound effects, battle sound effects and what I believe to be cry templates.

So wait.. I just extracted the stuff from Pokemon Super Mystery Dungeon. How do I get the midis from that? I have bcwav, scar, and cstm. I don't have any midis.
Edit: nevermind I read foobar2000, I'll try it as I have it.
edit 2: foobar2000 isn't working, probably because I'm missing a plugin.

Forgot the program name, I'll have to go to sleep now though. I'll look for it tomorrow.

Yeah, but you should find out what is streamed and what isn't. That'll give you a clue what you can edit.

Ok I got Bcwav to play in vgmstream, and exported to wav. Still can't figure out the csar/cstm (midi) stuff which I what I really want.

CSAR/CSTM are .BCSAR and .BCSTM respectively. Yes, they're the file you dumped itself and the CTR music streams found in nearly every 3DS game.

I've been searching for awhile, got a few programs too but I still can't figure out how to use csar(bcsar) or cstm(bcstm)
I did get the bcsar extraction tool, but the only thing I can use out of it is the banner sound for the game I have (PMD Super Mystery Dungeon). I do have a folder full of names of sound effects, but I'm not sure how to play those either.

--------------------- MERGED ---------------------------

Ok, I got a program called Every File Explorer that is able to play CSTM!

i think you can only play .bcwav with foobar2000 but u need this plugin first if u dont already have it https://www.foobar2000.org/components/view/foo_input_vgmstream

Yeah, I got that working after awhile but it still only played the banner. But now I'm able to play all the stuff with Every File Explorer. Still don't know about conversion to midi, which is what I really want. I can probably use audacity to record my PC sounds while EFE is playing the stuff though, but thats not what I really want.

You can use EFE? To play everything? Only one of the two formats play for me

No, when I said "all the stuff" I meant all the music that was in the game I was using. It had sound effects too.
