That looks like it would do the trick, but it also looks like a daunting endeavor. I'd have to modify the design to work in my case with a full size NES case. All those mini jump wires between contacts is going to suck for me too. Plus I have no idea what those other parts (diode, resistor, capacitor, etc) are used for. I wish I knew more about electronic circuits. That's why I liked the Mausberry circuit so much, plug in, put the wires where they need to go, and you're done (after getting the script obviously). The PowerBlock was useful too because you just attach it to the GPIO pins. I still think doing something like the Mausberry would work best, but I'm not sure if they can support the amps. Waiting for them to reply.
