Specifications
The game was initially released in an updated cabinet with a new CPU core and a 32-inch high-definition CRT. The new dedicated cabinets are considerably less deep than their predecessors. An upgrade to current JAMMA DDR cabinets was made available in October 2006.
The CPU core is actually a modified PlayStation 2 with a hard drive upgrade and modified graphics processor to permit the HD signal display on the flat-screen CRT monitor. One of the criticisms about the arcade port of Dancing Stage Fusion was that it was essentially the home version game with only very slight modification played in an actual PS2. DDR SuperNova, however, is a whole new game made specifically for the arcade powered on a modified PS2. It has, however, been ported to a home version, though the home version and arcade versions have slightly different songlists (the main difference being different licensed songs for the arcade and home versions).
The game's user interface is inspired by Dance Dance Revolution Extreme 2, the Japanese counterpart Dance Dance Revolution Strike and its European counterpart, Dancing Stage MAX. The backgrounds of the selection screens rotate colors between red, blue, and green, and have a wireframe motif. The three main difficulties of normal gameplay, Light, Standard, and Heavy, were renamed to Basic, Difficult, and Expert.
