NEC PC Engine Arcade Card DUO

...back

The Arcade Card DUO was released late into the life-span of the PC Engine Duo line in Japan to give it a "boost" of power - this "boost" came in the form of the Arcade SuperCD.  Arcade Card games featured more detailed graphics and effects, better sounds, and bigger and better cinemas. This "DUO" version was used to upgrade DUO machines only.
