The Serial Native Accessory Converter(SNAC) board and adapters allow for interfacing cores with their native accessories(controller, zapper, etc). The SNAC also provideszero input lag for the controllers/accessories. The SNAC connects tothe USB 3.0 port on the IO board. Note: the Genesis/SEGA CD/32Xadapter requires an Analog IO Board v6.1 or Digital IO Board v1.2.

Connect the SNAC board,adapter, and extension cable to the USB 3.0 port on the IO board

Atari adapter requires a stereo cable and ADC inputfor the paddle controller

Jumper pins on the IO board should be set to IO and not 3.3V (required for Genesis/SEGA CD/32X/Master System adapter to work)
