<systemDescription>The CD-ROM² (pronounced CD-ROM-ROM) is an add-on attachment for the PC Engine that was released in Japan on December 4, 1988. The add-on allows the core versions of the console to play PC Engine games in CD-ROM format in addition to standard HuCards. This made the PC Engine the first video game console to use CD-ROMs as a storage media. The add-on consisted of two devices - the CD player itself and the interface unit, which connects the CD player to the console and provides a unified power supply and output for both.
It was later released as the TurboGrafx-CD in the United States in November 1989, with a remodeled interface unit in order to suit the different shape of the TurboGrafx-16 console. The TurboGrafx-CD had a launch price of $399.99 and did not include any bundled games. Fighting Street and Monster Lair were the TurboGrafx-CD launch titles; Ys Book I and II soon followed.</systemDescription>
