Update for future internet users: It was the PCB. I picked up another copy and it works fine. One of the superguns I bought (the more expensive one) is definitely dead too though which complicated the diagnosis. It's a shame to throw the PCB out but it seems like the cost of repair would...

OK it's not letting me edit the above post, but I checked all 5 chips labeled 74299 at pins 10, 17, and 20 with the black probe at 10. Red probe at pin 20 yielded ~4.96 for all of them, and 10 to 17 was fluctuating which is apparently normal and a logic probe is needed to get a more detailed...

Update after removing all socketed ICs and spraying with Deoxit: View: https://youtube.com/shorts/YgQXhv3jvjQ I'm getting color changes when I gently flex the edge connector using the adapter (see above video). It's green/black at its lowest position, orange-ish in the middle, and the usual...

STC, this is a fantastic piece of info that I couldn't find anywhere else. Generative AI told me the board was legitimate - it's almost as though those things are fallible machines trained on internet (mis)information. I feel more secure in my job already! I'll apply this knowledge when...

Hi all, Pleased to join this community. I'm going for the world record in Tiger Heli, so I need a working PCB. I shoulda hired a rocket scientist because it's one of the hardest things I've ever done videogame wise (getting my setup to work, not mastering the game. You can read the drama...

Thanks for the replies, gang. Yes, the PCB was sold as working. I have a 60-in-1 PCB that I got for about $35 and that at least is displaying correctly with the same setup although the up button does not work (might be the controller). I bought that and all the superguns and cables as new, so...

Hi all, I have had a lot of issues getting a supergun/PCB setup going. After ordering two each of superguns, PCBs, and finally monitors I’ve finally gotten the game to display something but it’s unfortunately too garbled to be playable. The color issue is modified, but not fixed, by selecting...
