based on the track title and executable name, it's presumably Jade Cocoon. Looking at the set at joshw...well, I can't open/play the files right now, but there's eleven psflib files and none of the minipsfs (?) are marked as such in their file name.
The associated NFO says: - Complete rerip using original driver. Added some additional tracks missing from the previous rip. Also, all tracks are in original untouched SEP format, which is why we have so many .psflib files.
- VGMToolbox used for data extraction, stub creation, timing, tagging, and automated PSF/MINIPSF assembly.
- PSF-o-Cycle v1.01 used for driver patching. See stub source in "src" directory.
- Thanks to 2ch-H for the original rip, it helped me find my mistakes. - Thanks to BiggsWedgeJessie for original tags, they helped me a lot.
The "src" directory isn't in the joshw set. It is in the same set at PSF Mirror #1, however, which also has the presumably correct files named as minipsfs. I'm probably missing something obvious, but I can't tell who made this set (since I can't open the PSF files at the moment).
