OK, I don't know if it's true but I found something in Redump.org:

The game is mostly in English.
This version supposedly works only with the System Card 1.0.

This version seems to work with all the official system cards.Found these codes for the disc but not sure where it's printed on disc/packaging if at all:
Juuouki (Japan) (HA10817)
Juuouki (Japan) (HA10109) - fixed ver.
All discs seem to have same data, same barcode, etc., the only difference is the CD inner ring and the number of data tracks on the actual discs.
Does anyone have any information on this second version and if there's any visual clue on the CD packaging to help distinguish one version from the other?
