Adapter to use Megadrive controllers on a Saturn?

[The Expanding Man]

I have a 3rd party arcade stick to use on a megadrive/genesis.

Anyone know if there is a commercial adapter to use a megadrive controller on a Saturn?

I have a similar adapter to use PS1/2 controllers on the Saturn.

Thanks.

I do not know of a commercial adaptor, but according to gamesx (link), Megadrive and Saturn controller ports are possibly pin-compatible, though I have not tried it myself. If this is true, then as long as you can get the proper connector from a 1st/3rd party controller or extension cable, you should be able to make a trivial adaptor just by wiring straight through to a standard male 9-pin D-sub.
