Sega Saturn joystick pinout and Megadrive adapter


There are a lot of pinouts listed for the sega saturn joystick connector out there on the web, but most of them use nonstandard naming for the pins, and have missing pins. Here's the complete pinout naming and how to reroute the pins to make the Megadrive adapter.

This is the Sega Saturn male connector on the joystick:

Note: The Sega Saturn is expected to recognize and work with Megadrive joypads, and multi-tap, but the Megadrive games won't recognize any of the Sega Saturn buttons or even the controllers at all.
