I would rather wire up the expansion audio in my NES than do something quite as ambitious as creating a passthrough cable like in that original pic. There are also much cheaper alternatives to the Castevania 3 cart that will not be missed if used for a donor cart, like Madara. I'm not sure if Madara's PCB would fit inside of a 5 screw NES cart though since it's bigger than Castlevania 3's PCB. I think it'd fit, although in the worst case scenario, the grippy indent on the cart might need to be partially dremeled away.
