These are a different codec to Xbox 360. This is ADPCM.
Using the FSB cutter from VGMToolbox will produce incorrect results as there are only three FSB files in this provided archive.
You'll have to manually split them using a hex editor or something as there's no other way to do it. The easy thing I guess is that the files are at rounded offsets so identifying them should be quite simple at least from the sample you provided.
This picture highlights what I explained above.

The three highlighted offsets, are where those three individual files begin.
After splitting them manually, use vgmstream to decode them into PCM WAV
