after more than 2 years desperately looking for ways how to extract the ISO and get to the actual game I found a link to this place.
Louigi was that kind, wrote the script and make it happened in a few days! So thanks again to this great man and this site. You truly are awesome.
So following this thread https://zenhax.com/viewtopic.php?f=9&t=4388
here is the next challenge in front of this project.
What we discovered is that there are not exactly files what we expected. There is no DDS, PNG...etc or known audio files or any other "game" extensions that I could work with.
Just 2 folders: "0A" and "0B"
I found that "0B" is full of audio, but just as ".dat"
I tried to import those files as raw data in Audiacity. I can hear the game files somehow, but the quality is just very poor. Voices full of distorted noise in wrong speed.
Here are the settings in Audiacity that gives me best results:edit: Photobucket is not working, so I made a short video with the screens, so please take a look below...
Louigi already suggested that it might be ADPCM codec.
Here is what I found in some of those files, just by opening them with Notepad:https://www.youtube.com/watch?v=7OeTH8SPaGk
I uploaded one of the shorter files in attachment as Luigi suggested.

I'm looking very forward for all your suggestions guys. Any ideas how to make those files editable is greatly appreciated!
