I want to test out my SNES an my LCD but i don't know how to complete this circuit doohicky. I am using a PSOne Screen and I am getting power from the PSOne's second regulator. I attached the stuff as it said in ben's book but i don't know how to complte the circuit. (ex: i don't know where to get the ground form the SNES and where to hook it up on the PSOne)
PS: I don't have the controllers attached.
I'm not 100% sure, but on my psxp I just soldered a wire to a ground terminal on the playstation and then connected it to the ground wire coming in to the psone screen for power.
Someone please confirm, or expand on what im saying before you try this.
