This Disk Writer version of Famicom Grand Prix II: 3D Hot Rally, using the Famicom 3D System, likely offers more content or enhancements over the cartridge-based versions. The larger storage capacity of the Disk System could lead to additional courses, game modes, or other features. The core gameplay revolves around 3D racing, though still with the technological limitations of the time.  Nintendo's involvement in the game's production remains consistent.
