These are what I bought. They don't look pirated, they seem to be by a pretty known soundtrack company.
Well, those are real soundtracks that exist, but, the ones you got, are bootlegs. They're made by Son May, I have plenty of stuff by them, though I prefer when I find the real thing. I believe all of Falcom's recordings(atleast, back then) are on King Records, not SM. Let's see, those are called Music From, I don't have those ones, not sure which arrangements those are.
