【Included Items】 Main Unit x 1, Made in Japan (Late Model) Nintendo Official Controller x 2 Nintendo Official Stereo AV Cable x 1 Nintendo Official AC Adapter x 1 Super Mario World (New Battery Replaced) Powers on immediately, operation confirmed. The main unit and controllers are provided as-is, with only disassembly and cleaning (no bleaching) to maintain their current condition. (To prevent deterioration) The controller's internal circuit boards have been cleaned with anhydrous ethanol to remove dirt, and the internal rubber pads have been replaced with good ones if unusable. All controller button operations have been tested with Street Fighter ZERO 2, confirming all button functionality. (Including the Select button) The main unit's terminal parts have been maintained for easy startup. (Contact restorer applied) The software has only been polished. The main unit and controllers have been polished with a dry towel sprayed with silicone shine spray. Regardless of capacitor values, all 10 electrolytic capacitors inside the main unit have been replaced with long-life, new electrolytic capacitors from Nippon Chemi-Con and Nichicon. (Replacing only some would cause the remaining old capacitors to fail sooner) The AC adapter has been replaced with long-life, new electrolytic capacitors from Nichicon. The plug and the terminal part inserted into the main unit, which are prone to poor contact, have been polished with an abrasive to improve contact. Maintenance has been performed so that the power turns on when inserted into the main unit's DC IN, eliminating the need to search for the power-on position. After completing the capacitor installation inside the main unit, the circuit board contacts were cleaned with a dedicated circuit board cleaner, and then a moisture-proof coating agent was applied. Stereo AV cable, S-terminal cable, and RGB cable are all Nintendo official products, and video and audio have been confirmed to work correctly, so any cable can be used. (HDMI operation has also been confirmed) If there are any problems with audio or operation, I do not list the item. To prevent a decrease in value, it has been fully maintained to be played in the same condition as when it was released, without bleaching, painting, or modification. Main unit test passed.
