I've been looking around seeing how someone can export the sounds and voices from Dante's Inferno for PSP.
I'm thinking they would have to be from either the .sbk or .str files judging by how there's different names for the .str files from the different regional releases

I attached Lucifer's files from this game hoping someone can help out with this

These seem to just be renamed FSB4 files, renamed the extension to .fsb, and used foobar2000 with VGMStream (I use it for extracting audio from 90% of games) and it opened, but the files are structured one after another with header included, can't remember if that's normal but programs I have for FSB stuff don't seem to like it, not sure if there's a script for it, but by cutting each section out into an individual file (the sections are easy to find, just search FSB4 and you'll find the next header, then delete all bytes prior), you could import them all one by one. Primitive but if you can't find anything else, this seems to work. These formats feel familiar though, I think Dead Space games use them, or something similar, Gibbed.Visceral stuff might work, though likely not for this version of the game. (looked it up after writing this and it seems it supports the xbox version Idk about PSP)

Just use this script with Quickbms. Thanks EdnessP in Vgmstream website
