MiSTer SNAC Adapter - NeoGeo DB15

The SNAC (Serial Native Accessory Converter) NeoGeo DB15 Adapter is the ultimate solution for enthusiasts seeking an authentic, lag-free experience on the MiSTer FPGA platform. By utilizing the USB 3.0 User Port on the I/O Board, this adapter provides a direct bridge between your original hardware and the FPGA core.

The PCB is crafted with ENIG-surface finish (Electroless Nickel Immersion Gold) for superior quality, ensuring long-term durability and high-speed signal performance.

Key Features:

• Absolute Zero Latency: Unlike standard USB encoders, SNAC connects directly to the MiSTer FPGA core, bypassing the OS/USB polling layer to deliver 1:1 native input response.
• Standalone Design: This is a standalone SNAC adapter, meaning it does not need any form of level shifter to run properly.
• Original Hardware Support: Fully compatible with original NeoGeo AES/CD 15-pin (DB15) controllers and arcade sticks.
• Broad Core Support: Supports compatible DB15 cores, including arcade cores from Jotego and other cores that support ENCC (Enhanced Native Controller Compatibility).

To use this adapter, you will need a MiSTer FPGA system equipped with an Analog or Digital I/O Board.

Software: This adapter requires a special version of the NeoGeo core which can be downloaded from https://github.com/MiSTer-DB9/Distribution_MiSTer/tree/main/_Console.

Important Note: SNAC adapters are designed specifically for MiSTer FPGA systems. Please DO NOT attempt to plug this into a standard PC, laptop, or generic USB hub, as it may cause electrical damage to your devices.
