  Identify cables on your cable

  Depending where you got your cable from, the wire colors probably won't match with mine, so you have to map each pin with a wire color.

  Multimeter probes don't fit so grab another wire to probe each pin. With multimeter set to continuity, in one hand hold a wire (on one end of the cable) to the multimeter probe. With the second hand (and a lot of dexterity) hold a short wire pressed to your multimeter probe and try to plug it into each pin in the connector side of the cable until you find the connecting pin.

  Write down which pin is connected to which wire. You can find pin numbers on the wiki page: https://en.wikipedia.org/wiki/Atari_joystick_port. Note that the view is as looking at your commodore/atari port, not at the cable! So when you count the pin number on your cable, you have to mirror it!

  Soldering

  Solder the SNES connector as (NOTE: SNES pin numbering starts from the square side, and the last pin number is on the rounded side) to the Arduino pins:

  • 1 -> 5V
  • 2 -> A0
  • 3 -> A1
  • 4 -> A2
  • 7 -> GND (on the other side of 5V pin)

  If you printed the enclosure, now it's the time to pull the cable through the hole on the bottom.

  Solder the cable to the Arduino pins:

  • 1 -> D12
  • 2 -> D11
  • 3 -> D10
  • 4 -> D9
  • 5 - not connected
  • 6 -> D8
  • 7 -> VIN
  • 8 -> GND
  • 9 -> not connected

  Check the pictures if you're having trouble.

  Flash the firmware

  Open Arduino IDE, connect the board, select the COM port and board "Arduino Nano".

  Get the code from the github (link in the links section) and flash it. It's the snes2c64.ino file you need.
