But it gets the job done......

Essentially neither the IPAC or the hacked controller will be passing current to the buttons/joys at the same time. Plus, if it is that big of a deal, i could always unplug the controller from the console anyway. (Did i ever even mention that it WOULD be hooked up to a PS2/XBox console via normal plugs/adapters? I dont remember. well I am!!!) I hope this clears up questions and hopefully does not open up too many more.

Well, both the IPAC and the contoller are "sinking" input (like Ed said). Meaning when the electronics see the signal being pulled down to ground, that triggers the button press. This means (like what is said) that both the controller and the IPAC are supplying voltage. In the original diagram it shows the voltage lines (from the respective devices) both going to the cherry switch. Like Ed said, tying these together could be bad news.
I would think you would want something like this: (sorry for the crappy MS paint image ::) )
Basically, tie all the grounds together and switch the voltage lines from the respective devices.
So Ed was right, but instead of the 2 contacts from the IPAC and the Hacked Pad being tied together, they are on different terminals on the switch, which means they are never tied together.

For me, I went to a computer shop and they were selling printer cables and serial cables for about 2 dollars each (since centronics connectors are a dead technology I guess they were cleaning house).
The serial cables were great. All the wires were in twisted paires (with matching color codes). So it was great to wire each button with matching pairs of wires on one end of the cable.....then wire to the keyboard encoder with the appropriate pair. (well, I tied all the grounds together but still the color coding helped here too).
This was the cheapest and easiest for me.
(plus I had waaaaaay more cable than I needed. I could wire up 2 more control panels with the cables I bought)

Sensei,
This sounds like a good option.. but what do you do if you require more wires than, say, a serial cable (db25?) has?
Can you use two db25's? And how does this effect the grounding of all the controls?
