I haven't been able to confirm that they work. They seem to be in a generally usable condition. However, they've been stored for nearly 20 years, so I can't be sure. These are old Famicom games, so almost all of them have the owner's name written on the back. The games without names are: - DRAGON BALL Z III: Ressen Jinzou Ningen - Takahashi Meijin no Boukenjima (Adventure Island) - Taruuto-kun (1) (as shown in the 4th photo) The Taruuto-kun game in the 4th photo was purchased used about 15 years ago, and is the one that has been tested most recently. The games that don't have names written on them, but have the titles handwritten on the top are: - Golf - Kyuukyoku Harikiri Stadium Heisei Gannen Ban (as shown in the 3rd photo) I hope to have a pleasant transaction. Please negotiate considering the shipping costs. Individual sales are possible. Please consult about the price. The price is a temporary price for listing. I've sold some items, so I've updated the product profile and photos.
