So I've been building my first supergun, and I based it around the Retroelectronik Progamer. There are a lot of things I've liked so far with this unit, and I do have things up and running with an undamned usb decoder wired direct to the screw posts. That being said, I ran into a bizarre snag when trying to use the db15 controller ports. I purchased saturn controller adapters from RGB, and after chatting with him for a moment he pointed to the fact that the progamer doesn't use the same pinout. If that was my only issue, this wouldn't be too bad as I could just cut traces and rewire the controller ins on the supergun, and I'd have problem solved.
But here is where things get really weird. When I plug an adapter into port one, the supergun won't even turn on. The second I unplug the controller from port one, it turns on then. If I plug it back in, the supergun shuts off. Once, I even saw a spark leap from the metal shield on the adapter to the metal shield of the port. Luckily, the adapters don't seem to have been broken from this.
I started poking around with a multimeter and discovered that the second controller port doesn't seem to be grounded at all, odd. Then I discovered that somehow the first controller port's ground (including the metal shield) is shorted to the 5v rail!
Has anybody else had any or heard of any similar issues with this supergun? Is this a thing that could just occur from a manufacturing defect? I tried to write the seller but for some reason support requests error out on their website, and I tried ebay and have gotten no response.
I suppose worst comes to worst, I can just tap the pins on the bottom of the saturn adapter and wire them into the screw posts on the gun since it seems those work at least. This is a less than elegant solution, but I'm not sure how to remedy the weird controller port wiring.
Super weird!
Any thoughts/advice are greatly appreciated.
