# DaemonBite Sega Controller To USB Adapter
|
||
|
|
## Introduction
|
||
|
|
This is a simple to build adapter for connecting Mega Drive (Genesis), Master System (+ Atari and C= controllers) to USB. It supports 3 and 6-button Mega Drive controllers and 1 and 2-button SMS/Atari/C= controllers.
|
||
|
|
|
||
|
|
The input lag for this adapter is minimal. Here is the result from a test with a 1ms polling rate on a MiSTer:
