|Fast facts on the RAU-30|
|Made for: PC Engine SuperGrafx|
This short article is in need of work. You can help NEC Retro by adding to it.
Unlike the original PC Engine and many of its hardware revisions, the SuperGrafx is too bulky to fit into an Interface Unit, and thus communicate with the CD-ROM². The RAU-30 solves this problem by acting as a glorified connector cable, albeit one whose connector is PC Engine-sized. It is considered an inelegant solution to the problem - the Super CD-ROM² is designed in such a way that neither a RAU-30 nor a Interface Unit is needed to play CD games on a SuperGrafx.
