The new kit should handle both the scoop of the old disc tolls and the file conversions for audio.
I won’t raw post the audio but if you have an iso file and legal copy of the game, I have verified the voice lines get extracted/converted to mp4 clips that pair with cutscenes.
Most music is a sound font.
Edit: one caveat that I tested on a US copy of the iso. Let me know if you try it on a Japanese one and get an error.
