That byte at every offset 8 of the extracted files (in reality it's offset 0 because the first 8 bytes are the PSF header) reminds me to an adpcm codec I have already seen but don't remember what.
So it's not pcm.
Are you really sure it's the PC version?

Eh no, I prefer to stay out from audio stuff.
Check with hcs if he has ideas about that codec.

Here's stereo PSF decoder I made for you. Yes, its cutsom codec, very similar to PS ADPCM. Different number of nibbles and no flags.

Only works with stereo. Let me know if you need mono.
Also, no sample rate is in the file, so i write it as 44100, although some of them are 37000 or about that.

Segmented files look like stereo segments 1 second each.

after extracting segments its possible to load them all in order into editor, so they will be kind of complete set of music parts, which will play together:
