Most Nintendo collectors probably either aren’t interested in test cartridges or simply can’t afford them. However, for the ultra-NES-collector who has to have everything, there is the NES test cart. These were originally used by authorized Nintendo repair center technicians to diagnose issues on systems and accessories. It seems that the price on these is anywhere between $80 and $180 depending on the particular cart and, of course, a bit of luck at the auction.
Does anyone know if the SNES ones are less common? I’m no expert on these, but I’ve seen a lot fewer of those.
