* The booklet's credits for these tracks is different than the official website's.  Since it is possible for the website to be changed, and updated with new information or corrections, the website's credits are listed here.
   -The booklet states that Track 1.61 is composed by Go Ichinose, not Junichi Masuda, which makes sense as Track 3.41 (the GBP version) is composed and arranged by Go Ichinose [this is the same on both sets of credits].
   -The booklet states that Track 3.07 was composed and arranged by Junichi Masuda; Morikazu Aoki had no role in its arrangement.
