About 20 years ago, I received this item from the store owner when the store closed down. It was a demo unit. Therefore, the outer box has a magic marker "✖️" on it, as well as some dirt and damage. The contents have been opened for inspection, but it is said to be unused. Also, I have not checked the operation at this time, and I do not own the corresponding game console or software, so I cannot confirm its operation. It has been stored in a cool, shaded storage room, and as of now, there is no damage or soiling to the 64DD unit or the terminals of the accessories. We would appreciate it if you could understand the circumstances before purchasing.
