Hi. So, I finally have a setup that will allow me to to capture direct feed of NES games from an RGB-capable system. That’s good! The games look beautiful on my LED television, and they capture cleanly on my computer. However: There is one glaring gap in my newfound capture abilities, and that is my inability to properly capture light gun and R.O.B. games.
The lack of R.O.B.s games is no big, since there were a whole two of them, they can be played without R.O.B., and they are kind of terrible. The lack of Zapper games, though… that’s bad. I’ll miss out on being able to capture classics like Duck Hunt and Gumshoe, and that’s not cool at all. I could probably rig a Game Genie code to allow every shot to register as a hit, but that seems crummy and inauthentic.
So, I’m wondering if there’s a way to split my video signal and share it with a standard CRT television. I know it’s possible, but the challenge here would be to do it somewhere in the chain of connections before it hits the upscaler and becomes converted to a digital signal. Here’s a crude diagram of my setup (sorry it’s so rough, all I have on hand at present is a marker, an index card, and a phone camera):
I feel like the optimal strategy would be to plug the Mini-DIN-9 into a passthrough Mini-DIN-9 cable that also splits to composite video. This adapter wouldn’t need sound cables, since the audio connection is a separate RCA feed from the RGB video-out, just a yellow video connector. It seems like it should work, and the reading I’ve done online reveals people with similar setups using a similar approach. But the problem is that I can’t seem to find such an adapter like that for sale anywhere online.
Thus the questions I have are:
1. Would this in fact work, allowing me to capture HD video while simultaneously getting a lag-free signal to a CRT so light guns would function correctly?
2. Is there somewhere I can buy a Mini-DIN-9 passthrough cable that doubles as a splitter for composite video? Or else just a Mini-DIN-9 splitter and a Mini-Din-9-to-composite adapter? Whatever would work.
3. If no such thing exists, is there some sort of online service that creates weird custom cables on demand?
Thanks! I’m basically in over my head. Obviously.
