MiSTer SNAC Adapter - SEGA Genesis / Mega Drive

The MiSTer SNAC Adapter for SEGA Genesis / Mega Drive provides the optimal way to experience SEGA 16-bit, 8-bit, and add-on cores (Genesis, Mega Drive, Master System, Mega CD, 32X) on your MiSTer FPGA.

By connecting directly to the I/O Board's User Port via the Serial Native Accessory Converter (SNAC) feature, this adapter delivers true zero input lag, ensuring your original controllers perform exactly as they did on the authentic hardware. Key Features:

• Authentic Zero Lag: Bypasses all USB layers for the most responsive, delay-free control.
• Wide SEGA Core Compatibility: Works with original controllers for the Genesis / Mega Drive, Mega CD, and 32X cores.
• Controller Support: Compatible with original 3-button and 6-button controllers, as well as light guns.
• High-Quality Construction: Typically features a fully soldered PCB with an ENIG-surface finish for durability and quality.

Setup (Summary):

1. Ensure your I/O board is compatible (v6.1 Analog or v1.2 Digital or newer).
2. Connect the SNAC Level Shifter Board to the User Port via the extension cable.
3. Connect the SEGA SNAC Adapter into the Level Shifter Board.
4. In the Genesis core menu, set the Serial input option to SNAC (and adjust Swap Joysticks if needed).

This adapter (which typically uses 5V logic) requires the use of a MiSTer SNAC Level Shifter Board to safely interface with the MiSTer's 3.3V User Port. and you will find it here.
