IIDX Substream (GC983)

This is the Japanese version of IIDX Substream, a slight upgrade to IIDX 1st Style. Aside from some added songs, much of the game feels identical to IIDX 1st Style, including the intro video and the way the menu selection works. 4-key mode is still available, but the logo in the game start section has been updated. Much like the Japanese release of 1st Style, this has a warning stating that it is for use only in Japan. Unlike 1st Style, the dongle that boots this game cannot be used for the international release or the club version of Substream.

If everyone wonders how did he activate another difficulty for final stage music deep clear eyes, in the music selection, find a music which includes Another chart like GRADIUSIC CYBER, hold down VEFX button and press the white key as it changes the chart from 7KEYS to ANOTHER.
