All items are as listed above. The DUO-R main unit has been lens cleaned, pickup adjusted, partially solder repaired, and gear greased. It is a maintained item. Backup capacitor replaced. (5.5v 0.047f → 5.5v 1.0f) ※ The backup capacitor has been replaced with a larger capacity (new) one for save data power. ※ Due to the original specifications, save data may be lost if the power is not turned on for a long period. To preserve data, turn on the power for a few minutes every month. 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. The DUO-R box has damage such as scratches, stains, folds, and tears, and is in poor condition, so please consider it as an extra. ※ The serial numbers of the box and the DUO-R main unit match, but the serial number on the box is discolored, making it difficult to confirm the number. ※ The inner box (styrofoam) is missing. [Description of Extras] The AC adapter and AV cable were purchased new and used for multiple operation checks. Operation has been confirmed, but they are compatible products, so they are included as extras. Only Tengai Makyou and Galaga 88 have been initially tested for operation. There are damages such as scratches, stains, case cracks, and torn manuals. ※ If the Hu card software does not start up immediately, adjust the insertion position of the software to start it. ※ The extras are just extras, so no operational guarantee is provided 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 own. ※ Although it is a maintained product, it is a very old product, so no operational guarantee is provided after purchase. Returns, refunds, and transaction cancellations are not possible. Please purchase only if you agree to these terms. ※ Discounts are only possible for multiple purchases, and the discount will be the amount of shipping costs saved by combining the items.
