The business which [Eric Wright] works for just recently bought a Nintendo VS. It had Ice Climber installed as one of the titles however they asked the vendor if it was possible to switch it out for the Duck search ROM. They had the ROM however not a light gun that would work with the system. [Eric] suggested they buy it with Duck search as well as hack an NES Zapper to work with the VS cabinet.
Let’s take a step back for a moment. The Nintendo VS was a coin-operated gaming cupboard you would discover in an Arcade. luckily there’s rather a bit of info about the original hardware on the web. Some research study assisted him find that digitally the only difference between the arcade as well as house versions of the Zapper is that the sensor catch is inverted. This was fixed by replacing a transistor in the gun with a jumper wire. The next difficulty was figuring out exactly how to cable the gun as much as the second controller port. as well as lastly he patched the ROM to work with the inaccurate PPU as the right chip was not quickly sourced.
