All console controller. Possible?

[bobmonkfish]

Hello i was hoping that someone could help me in a technical question. 
 
I am doing as my Thesis Project a multi-controller. This comprises of research into the feasibility of designing a gaming controller that would be compatible with all the current gaming systems. Basicially a single game controller that can interface with Sony's Playstation 2, Nintendo's Gamecube and Microsofts Xbox.
 
I am just researching the project at the moment and was hoping that you could be of assistance?
 
I am wondering if you have any technical information as to the signals that are sent from controller to the console itself? Like are they digital or analog signals? What form are the signals in? and just any technical information regarding the controllers themselves. Encoding, decoding and compatibility between systems. Any information is welcome and appreciated.
 
Thanks for your help

It is an ongoing project which discusses many of the issues concerning different controls and how they are interfaced and interpreted by different consoles/computers.

I have this Soul Calibur II joystick made by Nuby...



...and it has plugs for PS2, GameCube, and XBox. So, all you have to do is hack one of these...

I've been doing it for years.

DC, USB, some psx pads, xbox all use digital signals. Not only that, most of them are active low, and also have a single ground for all buttons.

So, hacking 2/3/4 pads together is a simple matter of twisting the 'hot' wires together for each button. Then, also short all common grounds together. Lastly, you need to provide power to all pads in order to use any combination of them.

Here's an example....www.geocities.com/alainprice/ownzord3.jpg

It works on USB, Dreamcast, and the LED's count as a third system. It steals power from the pads, so no power supply is needed. All the wiring is passive.
