Not sure, I don't have the Saturn version.
This box is, presumably, "remastered" versions of
this,
this, and
this. What I want to know is how "remastered" they are, and whether
the later release of disc 4 in this box is identical (sans the bonus tracks of course).
Since that RayForce album came out alongside the game yet is entirely different from the PCB audio, I wonder if it's the "original" versions of the songs,
kinda like DonPachi.
