# DaemonBite Sega Controller To USB Adapter |

# DaemonBite Retro Controllers To USB Adapters |
||||
## 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. |
||||
This is a collection of easy to build adapters for connecting Mega Drive/Genesis (3/6-button), Master System, Atari, Commodore, Amiga (incl. CD32) controllers to USB. Support for more controllers is on the way (NES, SNES, NeoGeo etc.). |
||||
|
||||
The input lag for this adapter is minimal. Here is the result from a test with a 1ms polling rate on a MiSTer: |

||||
|
||||
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. |
||||
|
||||
## 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 |

## How to assemble (please ignore the switch) |

 |
||||
 |
||||
(The switch goes to pins GND-GND-2 even if the picture above shows it connected to GND-2-3) |
||||
 |
||||
 |
||||
## How to build |
||||
See the README files in the subfolders for build instructions. All the adapters are build around the Arduino Pro Micro. |
