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:

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)
  • Male end of Mega Drive controller extension (or DSUB 9Pin Male connector 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.
