How To Install a Playstation cable onto a Multi-Console Cthulhu

How To Install a Playstation cable onto a Multi-Console Cthulhu
This Instructable will guide you through installing a Playstation or Playstation 2 style controller cable onto a multi-console 'MC' Cthulhu.

All of the information about the Cthulhu project is available online in the Shoryuken.com forums:
http://forums.shoryuken.com/showthread.php?t=162026

Please be quite aware that this Instructable applies only to the MC Cthulhu; if your Cthulhu was purchased advertised only for PS3/PC use, then you cannot add a Playstation cable and expect it to work. Upgrade chips are available if you would like to turn your PS3 Only Cthulhu into an MC Cthulhu. If you are unsure which one you have, plug your arcade stick into your computer with the Start and Select buttons held down. if you see a new device called 'Cthulhu Bootloader' get installed, you have an MC Cthulhu. If you only see your arcade stick show up as normal, then it is not an MC Cthulhu.

Before heating up the iron and jumping in without a plan, it is very important you take a moment to get to know what to expect. Let's start by getting to know your Playstation cable.

You can use any kind of cable that has a male Playstation end, like the one pictured. You can scavenge these from dead controllers easily, or purchase a Playstation extension cord like I've done here. If you have an extension cord, cut the female end off as close to the end as you can, so you are left only with the male end and as much cord as possible.

Remove about 1 1/4" inches (3-4 cm) of insulation off of the end, exposing the insulated wires from the cable. If there is any sort of uninsulated wire or metallic shielding, go ahead and trim it off next to the end of the main cable insulation. If you have any heat shrink tubing of the right thickness to barely go over the main cable insulation, go ahead and slide it on now so you won't forget it later. The heat shrink tubing is optional, but definitely makes for a professional looking installation.

Strip about 1-2 mm of insulation off of the end of each of the smaller wires, exposing the copper. Get your multimeter ready to check for continuity, and a small piece of paper and pencil to jot down what you find.

The first picture below shows the proper name for each of the wires in the Playstation cable along with their pin number. 'N/C' means not connected; we don't need to connect them to the Cthulhu.
Our job now is to identify which of the colored wires in the Playstation cable go to which of the pins on the end. I will give a listing of which color goes to which pin on the extension cables I have used; feel free to use this as an initial guide for your testing, but you MUST check each pin of the cable. The colors on Playstation cables seem to have a very loose standard; for example I've seen DATA lines be white in one cable, and brown on the next. Use this to try and get your pinout done quickly, but it is NOT a substitute for testing yourself. (The Cthulhu Column entry should be ignored for now. Get the pinout done before ever heating up your soldering iron.)

Color Purpose Pin # Cthulhu Column
Brown - DATA - 1 - C
Orange - CMD - 2 - B
Black - GND - 4 - G
Red - VCC - 5 - V
Yellow - ATT - 6 - D
Blue - CLK - 7 - A
Green - ACK - 9 - F

(Color pinout for the newer shiny blue cables I sell)
Brown - DATA - 1 - C
Orange - CMD - 2 - B
Black - GND - 4 - G
Purple - VCC - 5 - V
Yellow - ATT - 6 - D
Blue - CLK - 7 - A
Green - ACK - 9 - F

Once you've pinned out the cable, locate all of the rest of the wires that don't match the pins, and trim them short around the end of the insulation. They aren't needed.

Is this playstation console cable installation works to each and every versions? Or it may differ for every ps2 cable.

It's a small controller board designed to make it easy to use arcade-style joystick controllers on game consoles or PC. Toodles designed and sells it. You can get the PC/PS3-only version at lizardlick.com. The multiple console version will be available with them soon.
