Released in Japan in 1988, the NEC PC Engine RAU-30 ROM² Adapter is an official expansion accessory designed to enable CD-ROM² System compatibility with the original PC Engine. It connects to the rear expansion port and acts as an interface between the console and the external CD-ROM² unit, allowing access to CD-based games and enhanced audio formats. By bridging the base console with NEC’s optical add-on, it becomes a critical component of the early PC Engine upgrade path. For players it unlocks an expanded game library and improved audio capabilities, while collectors value it as a key piece in the modular PC Engine ecosystem. Show more
