This is instructable is a modified version of http://www.instructables.com/id/SNES-Teensy-USBPS3-Gamepad/ , which uses a standard SNES controller.
You will need the following items:
Super Advantage Controller
Teensy 2.0 USB Board (http://www.pjrc.com/teensy/ )
USB Cable (http://www.pjrc.com/store/cable_usb_mini_b.html )
Solder and Flux
Needle Nose Pliers
Knife or Blade
Mounting tape (or any double sided tape)
Step 1: The Super Advantage Joystick
Step 2: The Teensy USB Board
First, we need to put our program onto the Teensy. Download the Teensy loader application at:
Next, download our USB/PS3 program for SNES from:
This file is the program we are going to run on the Teensy. It tells the Teensy to behave like a PS3 controller. If you are a programmer, feel free to grab the source code and make your own modifications. I also have a hex file that tells the Teensy to treat the SNES gamepad like a USB Keyboard, which is useful for some Android tablets that have USB input, but don't support gamepads.
Now that we have the loader application and the hex file, we need to put the hex file on the Teensy.
Step 1: Connect the Teensy to your PC
Step 2: Press the reset button on the Teensy
Step 3: Select the hex file you downloaded above with the loader application.
Step 4: Press 'Program'
Step 5: Wait a few seconds...
Step 6: Press 'Reboot'
Step 7: Wait a few seconds...
Step 8: You are done programming the Teensy!
Additional instructions for connecting and programming the Teensy can be found at http://www.pjrc.com/teensy/first_use.html .
Step 3: Preparing the wire harness
1. (Upper Left) Use a blade and cut down the middle of the rubber stopper (KEEP FINGERS AWAY FROM BLADE!)
2. (Upper RIght) Cut the cable off at end of the stopper.
3. (Lower Left) Strip the cable at the other end of the stopper.
4. (Lower RIght) Use some pliers and pull the cable housing out of the stopper. You can cut away as needed to make room for your cable.
Step 4: Soldering to the Teensy
White Cable (VCC) -> Teensy VCC
Yellow Cable (CLOCK) -> Teensy PB0
Orange Cable (LATCH) -> Teensy PB1
Red Cable (DATA) -> Teensy PB2
Brown Cable (GND) -> Teensy GND

You can test your new gamepad in Windows 7 by running "joy.cpl". Highlight the controller and select 'Properties'.
