Any news about the spk files? It would be very nice to have all the sounds of the game. I already done this thing for Star Ocean 5, but Anamnesis is too complicated for what I can understand.
Today I was trying to understand a bit how to open these SPK files, and apparently it is possible to decrypt them with SOADec_U2 or the slz BMS script. But, I still don't understand what kind of archive is this. The header is .ISF I'm sure they are archives that contain a series of AAC audio files.
Ok, with Nova File Extractor is possible to extract OGG files inside some SPK files, but not AAC. It's better than nothing. We can now extract every voices from the home, some dialogues and every enviroments sounds. AAC files are used for battle voices, sounds effects for skill, magic and menu.
