QJ.net: "Here's a new release of the anonymous Japanese coder's own gpSP mod. Keep in mind that this mod is different from the Kai releases, although some of it is based on gpSP Kai.
This release reportedly fixes some sound bugs found in earlier versions. For some reason though, I kept having trouble with the BIOS file. The BIOS I use for gpSP Kai doesn't seem to work with this one, so I couldn't really check the sound quality. Hope you guys have more luck."
