MiSTer SNAC Adapter - PC Engine / TurboGrafx-16

The MiSTer SNAC Adapter for PC Engine / TurboGrafx-16 is a specially engineered solution that addresses the unique, high-speed communication requirements of the PC Engine controller system.

While standard SNAC boards work for many consoles, the PC Engine's intricate controller accessories—such as the auto-fire switch, 6-button controller, TurboTap (multitap), and PCE Mouse—demand faster signal timing.

This adapter was specifically designed to overcome the limitations of regular open-collector SNAC boards, where the pulse rise time is not fast enough to reliably handle these advanced peripherals. It ensures true zero input lag and 100% compatibility with all known original PC Engine and TurboDuo controller hardware, delivering the most accurate experience possible.

Key Features :

• High-Speed Circuitry: Custom-built to meet the stringent timing requirements of the PC Engine bus.
• Full Accessory Support: Guarantees reliable operation for accessories that fail on standard SNAC boards (e.g., auto-fire, TurboTap, PCE Mouse).
• Zero-Latency Input: Bypasses USB polling for true, original hardware-like responsiveness.
• System Compatibility: Compatible with original PC Engine and TurboGrafx-16 controllers.

Compatibility Note: This dedicated adapter plugs directly into the User Port (USB 3.0) on a compatible MiSTer I/O Board (Analog I/O v6.1, Digital I/O v1.2, or newer).

This is a stand alone SNAC adapter does not need a level shifter to work.
