- jonthysell's SegaController library;
- Arduino (tested only on Nano boards, other boards may need the pin numbers in the code to be changed);
- Male DB9 connector.

Wiring Diagram:
After installing the "SegaController" library on your Arduino IDE, upload the code (SG_to_JAMMA.ino) to your board. If you experience random button presses, uncomment the first part of the "void setup()", which activates the software pull-up on the output connected to the JAMMA.
Huge thanks to jonthysell for their amazing library.
Also, thanks to pcbjunkie for their "ARDUINO GENESIS CONTROLLER INTERFACE", which served me as a starting point for this project.
