I'm sort of hijacking this thread as a place to post my thoughts on the game and the project as they come to me.
So, the music:
I uploaded the soundtrack to my mp3 player today, and with a bit of bass boost, I came to realize that the PSG songs in this game, which pretty much make up the whole soundtrack, are great. I've heard a healthy share of PCE chiptunes, and this stuff is both well composed and well programmed. The songs compliment the atmosphere of each area and event very well, to the point that they really enrich them. I encourage anyone to try to appreciate this as they play the game.
Some people might be disappointed that there aren't more redbook music tracks. It may be alarming that the final boss fight has the only in-game BGM to come from the CD. However, I think they made the right choice in using the PSG for most of the music. See, there are 52 PSG tracks, totaling to 68 minutes without any looping (based on the soundtrack CD). But wait, between the title screen, intro, ending, voiced cutscene tracks and other stuff, there's 54 minutes of redbook on the game disc already. So, instead of trying to cram in too much and forcing you to listen to the same few songs for the entire game *cough*emeralddragon*cough*, you instead get to enjoy 6 or so unique tracks for each of the games 8 chapters spread over 10 hours. None of it gets old.
