【Set Contents】 ◯ DUO-R Main Unit ◯ Arcade Pad (Controller) ◯ AC Adapter 【Bonus Items】 ◯ Xanadu: The Legend of the Wind ◯ Super Momotaro Dentetsu II ◯ AV Cable [Description of Items Included in the Set] Operation has been confirmed. The items are all as listed above. The DUO-R main unit has been lens cleaned, pickup adjusted, partially solder repaired, and gear greased. The backup capacitor has been replaced. (5.5v 0.047f → 5.5v 1.0f) ※ The backup capacitor (supercapacitor) is for save data power. It has been replaced with a larger capacity (new) one than the original. ※ Due to the original specifications, if the power is not turned on for a long period, it may discharge completely and save data may be lost. To preserve save data, please turn on the power for a few minutes every two months or so. The data retention period is considerably longer than the original. The controller has been maintained using anhydrous ethanol and contact spray on the internal terminal parts, but since there is no software available to me that uses six buttons, the operation of buttons III, IV, V, and VI has not been confirmed. Therefore, the controller is treated as junk for safety's sake. [Description of Bonus Items] The software used for operation confirmation is also included as a bonus. The software has been checked for initial operation. There are damages such as scratches, stains, cracked cases, and torn manuals. Accessories are missing. The AV cable was purchased new and used only a few times for operation confirmation. Operation has been confirmed, but it is a compatible product, so it is included as a bonus. ※ The bonus items are just bonus items, so there is no operational guarantee after purchase, and no compensation, returns, or refunds will be provided even if there are damages not mentioned. ※ There is a possibility that the software may not start depending on the condition of the software you have. ※ Although it is a maintained product, it is a very old product, so there is no operational guarantee after purchase. Returns, refunds, and transaction cancellations are not possible. Please purchase only if you can agree to this. ※ Discounts are only possible for multiple item purchases, and the discount will be the amount of shipping costs that can be saved by combining the items.
