【Operation Confirmed】NEOGEO AES Console Set (One Owner) D Button Defective

This was carefully stored at my parents' home.
I brought it back to my place and looked forward to playing it someday, but I can't find the time to play games, so I've given up and am listing it for sale.

Please check the images.
The D button does not work.
If you have any questions or need confirmation, please ask before purchasing.
This item is about 30 years old, so please purchase after reviewing the following and the images to your satisfaction.

[Main Unit Set]
Recommended for those who value the box, styrofoam, etc.

●The main unit, controller, and cables have all been confirmed to be working.

※Note※
The included controller's D button does not work, so it is recommended for those who can repair it or already own a separate controller.

●Memory Card
Comes with box and instruction manual.
I didn't know how to confirm its operation, so I'm including it as a bonus.
I think this is a good deal as memory cards alone sell for over 7,000-8,000 yen on Mercari even without confirmed operation.
