UFC Sudden impact (PS2) GZMVS.RBB

[Game Ripper]

Hi guys, I hope you can help me with unpacking this bigfile with Sony 4-bit ADPCM audio in it. Needless to say I'll be very grateful for any help!
There're 2 files with RBB extension on disc but I probably need just this one as it holds most / all sounds from the game. Here you can find 11 MBs from file start & 11 Megs from its end, I hope this is enough to figure out the format. If extraction of contents is done properly I'll supposedly get hundreds of headerless tracks and I can take it from there (I guess, finding correct interleave value shouldn't be hard if tracks were split the right way).
Thanks in advance and good luck with this sound bank!

Stereo files may not sound correctly.

Thanks a lot, your script works just fine! BTW I wasn't quite expecting to get tracks extracted with their rightful titles so this is 1 more good feature of the BMS.
As for "stereo files may not sound correctly" - well I was prepared to set/tweak interleave value in resulting files so it's no big deal after all.
Big thnx again and goodbye!
