I dunno.....it might be a good idea to give him time to work out any possible interface bugs between FF7Music and the PSF plugin first, then apply his experience on FF8, but seeing as though he mentioned in that other thread about having some 15,000 word report to do, I don't think now would be a good time to ask, lol.
Another thing would have to be filesize. At this point, to use the FF8 PSF files on FF8, you'd be required to download roughly 28mb of data, and then use whatever PSF interface that would be thought up to do it; while in the meantime you can get roughly the same amount of quality with Samuel's DLS, which is also a 28MB file (due to the compression), and already works with the existing music playback system....
Essentially, I'm saying that using FF8 PSF files for BGM playback would be a lot more reasonable an idea if/when they manage to convert it to .miniPSF format, since that may decrease the file size by some degree.
