Game Genie "video game enhancer" for the Nintendo NES. Allows you to enter a set of codes to change game parameters, grant extra lives and create weird effects. My favorite code to enter was "PIGPAK". Includes the Game Genie, manual / code booklet, and an unused flyer you could mail in for a subscription to receive new codes for new releases. Tested and working. Please check my other items, as I have many other Nintendo games listed for sale. Free shipping anywhere within the U.S. International shipping will vary by destination; please ask if interested. I welcome lower offers, especially if you are buying multiple items at once. To make a lower offer, add the item(s) to your cart and on the checkout page you will be given the option to name your own price. (If you are not seeing this option, it may be because your state requires sales tax. Bonanza is working on a fix for this issue, but you can also send me a direct message with your offer.)
