: I've already hacked a DC stick to my arcade controls, and I'd like to do the same with a USB gamepad to interface with my Mac, however, the cheap one I've got kicking around here (Gravis Gamepad Pro) has one problem - each button has it's own ground. If I wire this up, I'll have to re-wire my Dreamcast controls (I'm going for a common set-up here so I can use the same controls with different hacks)
: Has anyone hacked a Mac-compatible gamepad w/common grounds?
I used to have a control panel setup like the one you want, inside the panel all the wires were separate including the grounds. The wires connected to a 50 pin cable. I had two cables that would plug into the back of the control panel, one connected to a PowerRamp which needed each button to have it's own "ground". The second cable connected to a PlayStation pad, I just took all the ground wires from the cable and tied them together to make one ground. So the trick is all in the adapter cables. Hope this makes sense.
