1, This Serial Native Accessory Converter (SNAC) is the USB3.0 version that allows you to connect console-specific input devices to your MISTer. Connecting original controllers is achieved by using individual adapters. 2, Looking for zero frames of input latency? SNAC provides this when connected to the MISTer FPGA 10 board. This potentially offers the best experience for gaming enthusiasts or speedrunners who demand precise gameplay with original controllers without lag. 3, SNAC also works with light guns such as the Zapper, Super Scope 6, and Master System Light Phaser, but an analog CRT screen is required to use the consoles' original controllers. 4, For MiSTer, SNAC support is enabled in the following cores including SNES, Master System, / Drive, CD, 7800, and TurboGrafx-16/ TurboGrafx CD. The appearance and color of products from different batches may vary, which does not affect their use.
