    Hello all,

    I have been looking around the forum and online to see if I could find a pin out or at least a high quality photo of the back of the Legend of Zelda NES PCB but no luck. My question is this:

    On the back of the PCB just above the positive terminal there are two vias right next to each other and I'm not sure if they're supposed to be bridged or if I hit them with my soldering iron. If anyone could post a good picture or knows off the top of their head that would be incredibly helpful. Thank you!

    Here are the vias in question, I just grabbed the best photo I could from a google search as I'm not at home with my board.

    Thank you again!

    Edit: attached another photo.

    it would appear that both of those are already through the ground plane, a simple test would be to use some desolder braid, take off the solder, then test for connectivity with a voltmeter, if theyre already connected, then a bridge would make no difference

    In the event that anyone has this question and comes to this thread, I found that they are indeed bridged and the game runs fine!
