ROM Hack Converting WAV to SWAV

[SaitoKojima]

Hello.

A few friends and I are working on a dub for Megaman Star Force 2 and 3 (when it comes) to feature our own voices, instead of MMSF2's lack of voices and MMSF3's energy-lacking crap.


Actually getting it done won't be much of a problem, except for the fact that we don't know any sort of way to change our WAV format clips into SWAV, which is the DS standard for voice clips.


Does anyone know how to do this?

No tools for this that I know of* (midi to sseq is another thing http://kiwi.ds.googlepages.com/ ) but:

possibly http://ccrma.stanford.edu/courses/422/projects/WaveFormat/
http://www-mmsp.ece.mcgill.ca/Documents/Au.../WAVE/WAVE.html

a copy of audacity and a hex editor should do the trick.


*the above is roughly what I do when playing around but I have not checked tahaxan forums or the Chinese rom hacking sites in some time and hacking tools tend not to spread as much as general homebrew.

In all honesty, if I knew the right people I'd hand this project over to one of you guys and see what you could do.


But for now, thank you, I'll see what these pages can do to help.

Sorry for double posting but...

I wanted to bump this up in case anyone else knows some info on this.

Was doing some poking around and there is an SDAT repack tool available:

That does not really help you though as it is designed for those who already have the files in required format.

However I also have a link to the source code (looks to be largely C) to ndssndext:

It's strange... Something that seems so simple like this is so hard to get done.


Yet there's people who can make Golden Sun on GBA have full-voice acting when the game originally was never meant to be able to do that.


It's just really weird to me when I think about it.

SWAV is an ADPCM variant that is proprietary to Nintendo. No public format description exists that i know.

You'll need the SDK.

 

[SaitoKojima]

What's "the SDK?"

I'm not exactly too big on the whole ROM hacking gig, this is likely my first project ever.

you can examine for understanding swav format

Thanks for that, but I'm trying to the the opposite.

I'm trying to take WAV format files and insert them into the game so that they replace the original version's voice acting with my own. Not extract the game's voice clips out for listening and stuff.

 

[FAST6191]

Both theli and I were fully aware of this when we posted it up. I have not pulled apart swav2wav yet but ndssndext had a nice guide to building a WAV file which means you can strip the data and between what it reads, cuts and that specs listed you can go in reverse.

As for "simple like this is so hard to get done" it is not all that difficult just that most people who do it would do with a hex editor and the stuff linked up.

Try using Tinke, it has the feature to convert WAV audio into SWAV, then create the new SWAR and save the SDAT. I didn't test this feature but it should work

EDIT: This is the last version of Tinke with this feature: http://dl.dropbox.com/u/3981393/Tinke/Tinke%20rev83.zip

 

[Daviex]

Can you explain how to do this?

ok, i've inserted wav with Import button, removed Active Loop, but don't change anything O_O

I found problem.

When i go to import, it don't overwrite the file, but it only write with old voice.

Name is the same, and when i go to Save SDAT it corrupt file.

Well, the other version has a little bug, sorry, download again from here: http://dl.dropbox.com/u/3981393/Tinke/Tinke%20rev83-1.zip
1- Open the SDAT file to modify (you can open it from a game)
2- Select the file and click on the button "View"
3- Select the SWAR file and click on the button "Unpack"
4.- Select the SWAV to modify, click on the button "Import" and select the wav file to convert
5.- Click on the button Accept in the window (you can edit this values that are in the header of new SWAV file)
6.- Select the SWAR file again and click on the button "Pack"
7.- Click on the button "Save SDAT"
8.- If you have opened a game, you must click on the button "Save ROM".

EDIT: ok, I will look at the error you've said

 

[Daviex]

Hmmm, to me continue to crash and corrupt the SDAT when i go to save o_o

I send you PM, read
