NES Game Genie, with Manual/Codebook + Eight Code Update Booklets

Description

I am selling our sons’ huge collection of video game consoles, games, and accessories.
This listing is for the NES Game Genie, the Programming Manual and Codebook, and eight code update booklets.
Volume 1, Nos. 3 and 4
Volume 2, Nos.1-4
Volume 3, Nos. 1 and 2
The programming manual has some bent corners and page edges, but no writing or tears.  There is shelf-wear on the cover.
The first two update booklets have a little wear, with some rubbing.  There's a small tear at the bottom of the cover on #4.  Volume 2, #2 has the reorder form cut out of the back cover.  The others are all perfect.
My son tested the Game Genie when he was at home.
This is a non-smoking household and always has been!

I am listing a lot of games, and am willing to work with you on combined shipping if you buy more than one. eBay requires immediate payment on buy-it-now listings, but if you buy another before I ship the first one, I will refund some of your shipping cost. Or, if you let me know which one(s) you want, I can combine the listings with a lower shipping cost.
