This is a project I have been wanting to revisit and make a more professional version.
I originally did this project because there were many people out there using the controller to hook to their MAME devices and were doing some horrible conversion by snipping off the connector and doing a wonky solder to a disassembled USB game controller. I couldn't fathom destroying so rare of an object to save a few bucks to get it to hook up to a PC.
My first go at this project looked like this:
Something that irked me as I learned better processes is that my cable really needed some stress relief, didn't need so thick of wires, and really needs a case to protect it inside a cabinet.
Upgrading it to use a Teensy 3.1 would be nice as well, though Teensy 2.0's are still available.
