I have made the twin Saturn controller adapter for the PC but have a small problem. It works fine with the regular controller but does not operate with my wireless adapter and controllers. I had the same problem with my Sega Genesis adapter. It works fine with the regular controller but does not work with the wireless Genesis unit. All the pins on both of the adapters are correct and I have checked them several times. My conclusion is that the IR unit is not getting the power it needs to operate since the led that flashes to signal a button press or directional pad movement does not light when any of the buttons on the pad are pressed. And they do work on the actual machines , so it is not faulty equipment. I know that the PSX controllers with force feedback require an external power supply to get that feature to work. Is it possible that the IR units need an external power supply as well? And would this be possible? What pins require the additional power and at what voltage and amp. Thanks.
