Released in Japan in 1988, the NEC CD-ROM² CDR-30 is the groundbreaking add-on that brings CD-based gaming to the PC Engine during the early CD era. This accessory expands the console’s capabilities with larger games, animated cutscenes, and enhanced audio far beyond HuCards. Known for its compact design and early multimedia approach, it becomes a defining upgrade for players seeking deeper experiences. Players and collectors value the CDR-30 for its pioneering status, its importance in Japanese retro gaming history, and its role in launching one of the industry’s first CD game libraries. It pairs with the IFU-30 interface to operate properly.
