IIDX Substream Club Version (GE984)

This is the club version of IIDX Substream. This allows linking with Dance Dance Revolution Cub Mix v. 2. This allowed DDR players to play exclusive songs available only when a DDR and IIDX cabinet linked and helped push the popularity of IIDX at the time. Aside from this added ability, this version seems identical to the Japanese release. Much like the internation and Japanese version of Substream, this requires its own dongle to boot and cannot share a dongle like IIDX 1st Style allowed.
