Dreamcast Controller HKT-7700 Visual Memory HKT-7000 SEGA Dreamcast Sega * I do not have an operating environment, so I have not been able to confirm the operation. I feel that there are no problems with the buttons and the feel of the controller, but please consider this as a reference only, as it is my personal opinion. I was able to confirm that the visual memory works by inserting batteries, but I have not been able to confirm it by connecting it to the main unit. Therefore, I would appreciate it if you could understand that this item is being sold as junk.
