DaemonBite Sega Controllers To USB Adapter
Introduction
This is a simple to build adapter for connecting two 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 (one port version):
| Controller | Samples | Average | Max | Min | Std Dev |
|---|---|---|---|---|---|
| Original 3-Button Mega Drive Controller | 2342 | 0.75ms | 1.28ms | 0.24ms | 0.29ms |
| 8bitdo M30 Wireless 2.4G | 2348 | 4.54ms | 8.05ms | 2.22ms | 1.31ms |
Parts you need
- Arduino Pro Micro (ATMega32U4)
- 2x Male end of Mega Drive controller extension (or DSUB 9Pin Male connectors and some wires)
- Heat shrink tube (Ø ~20mm)
- Micro USB cable

The Mega Drive gamepad interface is based on this repository : https://github.com/jonthysell/SegaController but almost entirely rewritten and a lot of optimisations have been made.
