I haven't played this in years and I pop it in for a go yesterday. I always assumed the music was redbook, but upon closer inspection, it appears to be produced using the Saturn's chip. Alls I gots to says is Wow. If I were to compare this to what was produced on PSone, like FFVII or some of the non redbook stuff on Wild Arms (which was really good, actually, but paled compared to the full orchestra stuff they had), I would have to say Saturn was capable of a lot more than the Psone was. I always assumed the PSone had better sound hardware. I guess now I know better.
