I can dump the SFX and voices for Valkyrie Profile 2, and I guess I'll do it for Star Ocean 3 since I've been meaning to anyway. It was Sony ADPCM last time I checked. BGM is a no go though. Check in with me next week though. It might take a bit to get through everything.
I don't have the Beyond the Labyrinth files, but I'm assuming they'll be in a BCSAR. How does the file system look?
