Yu-Gi-Oh! The Falsebound Kingdom .pac Audio Container by TheFirstHunt at 6:47 PM EDT on June 10, 2024
I've done quite a bit of looking and while there do seem to be a couple of rips online, I have no idea if they're complete or not and was curious if someone would be able to convert the game's .pac files/extract the DSPs/audio from them? I'm not even good enough to consider myself a novice at dealing with that file format and from what I've seen it seems like it's a bit out of my wheelhouse. Any help would be appreciated!

The game already has a complete rip which you can find in places like here and here. There's also some uploads of the bgm on YouTube as well. This has also already been talked about here on this forum as well.

If you're curious about how to rip the music from the game yourself though, you can just use a hex editor to extract each of the Dual-Stereo DSPs and used vgmstream to decode the audio from each of the tracks (make sure they're in proper dual-stereo naming so they can be properly decoded as one track). Let me know if that answers your issue!

It does, thank you! I was aware of the other posts, and the rips online, but was worried they might be missing some short pieces like jingles or things that might be considered sound effects rather than music. That was the main reason I was trying to figure out how to do it myself. There's a grp.pac along with the str.pac, and the str.pac is the only one that seems to have been extracted/decoded online. That may be because grp.pac doesn't contain any audio, but like I said I'm not even a novice and can't make heads or tails of hex editing. For instance I don't even know how to begin using one to extract the DSPs from the .pac files. Even after reading the other post on this forum it doesn't make any more sense to me. So it might just be something I have to wait to do until someone can literally hold my hand through the entire process lol. Getting the DSPs converted is easy enough with vgstream though, so at least I'm capable of dragging a file onto another file I guess.

I dug out my old code for extracting the str.pac, creatively dubbed unpacman. It looks like this is a pretty simple format, but there's one major wrinkle that comes up in the grp.pac and system.grp (which I think contain sound effects): There can be multiple DSPs in each group, and their (otherwise standard) headers refer to positions in the overall group. vgmstream only handles the streams in str.pac, which each have a header specifying only one DSP.

There may be a way to handle this with TXTH, but it isn't straightforward enough for me to be able to deal with it tonight.

Thank you for pitching in @hcs! I wish you the best of luck with creating a TXTH for grp.pac and system.grp!

I was just in the middle of extracting some of the DSPs from system.grp and was hoping to upload them as soon as I was done extracting all of the sfx from that specific file.

I'd say go ahead, I don't know when I'll get to it

Thank you to both of you! I'm in no rush, I'm just surprised anyone at all cares about an admittedly mediocre game like this after twenty years anyway. I'm grateful for whatever either of you are able to turn up.

I've extracted all the sfx files from system.grp right here!

It took me a little longer to extract them because I had an issue around the 33rd DSP. I learned that there are more headers than DSPs, so I had to make sure that I paired the correct headers to the DSPs so I didn't mix any of them up.

I'm still trying to extract grp.pac, but it's going to take a very long time to extract all of the sounds until we have a TXTH for grp.pac to make it much more easier and convenient.

(***editor's note*** please be mindful of your volume! Some of the DSPs are louder than the others)
