New version of MS-ADPCM?

[Savage]

Batman Arkham Origins Blackgate Deluxe Edition and Cabela's Hunting are using this "new" code, i can play Cabela's files with Vgmstream, but the game can't play the pcm files and Batman Arkham Origins Blackgate files can't be played.

Two points:
1. It is most similar to MS IMA, with lots of redundant data in frame headers to allow frame-accurate seeking.
2. I am not confident that decoding it as MS IMA, after rejiggering, is completely correct.

Sorry! thanks for the correction.
