28/09/2023: PCE RGB Adapter V2 Changes:

  • Stereo audio CD support integrated into design instead of previous manual hotfix.
  • CSYNC & CVBS are properly buffered for increased compatibility with monitors/scalers etc.
  • RGB lines are correctly attenuated.

Slots into the rear extension port of any PCE CoreGrafx/TurboGrafx-16 etc:

Sync/cables: This adapter has the benefit of being able to use CSYNC & sync on composite output.

CSYNC: A standard Mega Drive 2/Genesis 2 RGB SCART cable wired for CSYNC may be used, we stock these here.
Sync on composite: HD Retrovision Genesis 2 cables are compatible and composite video is able to be used.

Case: the case is designed for the PC Engine Core Grafx line of consoles, we cannot guarantee it will fit other variations of the PC Engine. For TurboGrafx, we recommend using the board only version of the adapter.

Case colours: whilst we try to accurately photograph as best as possible, please bare in mind that the colours may appear slightly different depending on your monitor/display.

Case only option: Only case and fixtures are included, no adapter PCB. Only fits the PCE adapter board that we stock.

Support bracket purpose: protects the PC Engine Expansion port when using a free-hanging PCB. Assists in avoiding the connector from making bad contact or bending, insert the bracket first, and then the PCB with the connector.

Shout out to Martin Hejnfelt for the design. Save yourself from cheap and badly designed Chinese made alternatives and grab one of these today!
