This circuit makes it possible to use Sega Saturn peripherals (controllers, mouse) on a PC through an USB port. One can either build an adapter (Using the connector from a Saturn extension) or convert a controller by wiring it directly to the circuit.

  • The Basic controllers (ABCXYZ, L/R and Start buttons). Tested with:
    Sega HSS-0101, Sega MK-80116, Super Pad 8 (P-400), Horipad SS (HSS-11)
  • The analogic controller. Tested with: Sega MK-80117.
  • The mouse (aka "Shuttlemouse"). Tested with Sega HSS-0102.
  • Should also work with the twinsticks.
  • Multitap not supported.
Thanks to USB HID compliance, the adapter works immediately on most modern operating systems without installing special drivers. Tested under Linux, Windows 7/8 64-bit, MacOS X and Sony Playstation 3.

This project is an implementation of the following open-source project: Sega Saturn controller to USB adapter project.
