I have what it supposed to be a working SNES, but I don’t have a known working cartridge for it to confirm. I have some SNES bare boards I’m trying to asses, and some of them, when inserted into the deck, cause it to not boot at all- no power LED, no nothing. The only thing in common with these boards is that they have the extra pins on the sides. All of these boards are bad, for certain, but I’m wondering if this could indicate a fault in the deck? Any thoughts?
