Gmr_Leon: Could any of you that own the GOG version see if the soundtrack's accessible somewhere in the game files? I'm a little split right now between this and the Steam version, with the only edge the Steam version having being its more recent patch and the soundtrack availability.
If you could and would, you'd have my gratitude! =)
Well, I can tell you that on the Steam version, the soundtrack is locked away in "bgm.xwb", which isn't readable by user end players - it's a big wave bank you'd need to open with DirectX tools. I've no reason to assume the GOG version's file structure would be any different.
Remember though that the soundtrack is NOT included by default in the Steam version, so in total you're paying around $15 for it on Steam for the game + soundtrack, compared to $10 on GOG for the game. Considering that the so-called "official" soundtrack is far from all the songs in the game, with the fan soundtrack from years ago being far more exacting, you might be better off just nabbing the game for $10 on GOG, waiting for them to patch it to 1.01b here (if they haven't already) and looking into the fan compilation OST, which has 47 tracks to the "official" OST's mere 25.
