IIDX 3rd Style (GC992JA C01)

This is IIDX 3rd Style, the sequel to IIDX 2nd Style. From 2nd Style to 3rd Style there was a dramatic shift in art direction. A brand new intro video is present and the user interface style is more refined than 2nd Style. References to the CYBER-beat-NATION are present on both the arcade B1 poster and in the intro video. Many more style modifications are avilable as compared to previous releases as well. Both 4keys and 5keys mode is dropped from the play style select screen. There doesn't seem to be any visible differences between this and the downgraded version B01.
As a side note, this is one of my favorite versions of IIDX :3

3rd Style was the last style to keep a lot of the original house, hip-hop, and JR&B licenses that made up that original staff concept of bringing high quality, mainstream music into the beatmania series. This was also the last IIDX game that Reo Nagumo had staff involvement in as Sound Supervisor. It also introduced the Light 7 and Light 14 modes along with some of the most insane Another charts of its day.
