And thanks for pointing to bzip3, will include it into my bruteforcing queue.

There is a big chance that this is not the case, because when analyzing the acoustic spectrum (with the spek program) the audio extracted from A0.dta (the largest of them) called: "07b_SarasTheme.wav" has 22Khz - typical PCM audio quality...
