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:
|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|

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.
