Sega Saturn controller to USB adapter

Posted on Feb 7, 2014

This projects makes it possible to use Sega Saturn peripherals (controllers, mouse) on a PC through an USB port. Using the schematic and firmware available on this page, one can make an adapter (Using the connector from a Saturn extension) or convert a controller (if it has enough internal free space). Thanks to USB HID compliance, the adapter wor

ks immediately on most modern systems without installing special drivers. Tested under Linux, Windows 7 64-bit, MacOS X and Sony Playstation 3. William Schneider sent me the following picture of this project assembled in a breadboard. He also confirmed that everything works fine with the Sega HSS-0101 controller, and that firmware version 1. 1 works very well with the PS3: The following mappings are available. To enable specific mapping, press and hold the corresponding button, connect the adapter (or power-up the console/computer), and release the button. On the PS3, the SLS (default) and SLS Alt mappings are usually the most suitable. They have been reported to work well for Super Street Fighter IV, Tekken 6, BlazBlue: Continuum Shift, Virtua Fighter 5, Arcana Heart 3, Hard Corps: Uprising, Soul Calibur, Disgaea 3 and Mortal Kombat 9. The signal labelled as "+5v (Inp)" in the above mentionned webpage is in fact a logic output used by the Analogic controller and mouse. This signal is part of an handshake mechanism used to transfer a sequence of values. In fact, these peripheral communicate exactly like the Genesis multitap do. For details: For the USB connection, just strip the USB cable and solder the wires directly to the board. USB uses standard wire colors, but beware of cheap cables built with non-standard color codes. A microcontroller is a component which must be programmed in order to do something useful. So here...
