My TV only has one composite input and I hate switching cables every time I want to switch between my Genesis and SNES. Is there such a cord in which I could plug in the two inputs from both composite cables (Genesis and SNES) and just input the cord into my TV? Thereby avoiding switching cables constantly? Please note I am looking for a cord or a cable. I am NOT interested in switch boxes or anything that involves me flipping switches. Does such a cord exist, and if so please provide a link to where I can buy it (preferably ebay).
