NEC PC Engine CD & TurboGrafx CD Guide

Definition

NEC PC Engine CD & TurboGrafx CD refers to discs released for the "CD-ROM²" add-on made by NEC for the PC Engine (Japan) and TurboGrafx-16 (USA). Units with the CD-ROM add-on built in were also released named the PC Engine Duo (Japan) and TurboDuo (USA). Despite the name "CD-ROM²" they are functionally normal CD-ROMs.

Ringcode / Revisions

There are standard revisions evident from ringcodes. For example, SAAS, SABS, SACS, SADS, SAES, etc.
If a disc has SADS at the end of the ringcode, edit the datname to include SADS to identify it / distinguish it from other potential revisions.
Example (RE) datfile version vs. non-RE mastering
