Any way to extract and rebuild GT3's VOL file?

[60fpshacks]

Just as the thread title says.

I have a way to encode music for the game and I would like to add custom music to it.

Yep - I figured it out a few years ago, based on adeyblue's prior work with GTVolTools. The tool is available here.

Thank you much. I have been looking for this for a while. Any luck on getting GT4 Retail to extract and rebuild?

GT4FS will do that.

I have that tool, but can it rebuild as well? If it has that option I must have overlooked that in the txt file.
Edit: I had an older version of the tool. I will update to the newest.

I was wondering if you knew if there is a tool to decompress GT3 and GT4's ELF files.

I tried custom music on both GT3 and GT4. It won't play. It seems to have some other data that probably needs to be updated in order to play other music. I am guessing it has an external file that checks the file size and/or checksum.

I checked the interleave of both a file from the game and my custom music file and the interleave is the same. You can play the ads files on foobar2000 with the vgmstream plugin.

No idea, executable modifications aren't my strong point. I do know though that they have a ton of code outside of the main executable (in core.gt3 in GT3, I forget the filename for 4), but I don't think there are tools for that yet either.
