"DDR SuperNova" is the first in the series to support e-Amusement functionality. The service is used for Internet Ranking, updates, and content delivery. The service is not available outside of Asia. In addition, it was supposed to feature Link Data, designed to provide connectivity between the arcade and PS2 versions of the game, by means of a PS2 memory card. The reader was depicted in arcade flyers, but it was never released. This feature already existed in "Dance Dance Revolution Extreme" and several earlier releases, but used original PlayStation memory cards and readers instead, which "SuperNova" does not support. Supplier issues with Sony forced Konami to cancel the functionality. To compensate, Konami offered a coupon or soundtrack sampler for customers in North America who purchased the game in 2006.
