Thank you for viewing. This is a fully maintained PC Engine DUO, with the electrolytic capacitors replaced and the optical pickup adjusted. Both HuCards and CD-ROMs work smoothly. Furthermore, analog RGB (SCART) output has been added, and a double-shielded SCART cable is included so that it can be connected to video equipment such as a CRT or a scan converter. Also, by converting the save data backup memory to FRAM, save data can be retained almost permanently without a battery. Moreover, the save area has been increased to 16 times the original (16 banks). Images from the game are posted. These were captured with an HDMI capture device for game streaming. I am looking for immediate purchase, and due to the nature of the product, I cannot accommodate price negotiations, so please understand. [Included Items] ・PC Engine DUO main unit (maintained, RGB output added, FRAM custom 16-bank) ・Genuine game controller ・Genuine AC adapter ・Genuine AV cable ・Double-shielded SCART cable [Operation Check] ・HuCard, CD-ROM operation ⭕️ ・AV/HDMI video output ⭕️ ・Audio output (volume OK, left/right balance OK, no noise) ⭕️ ・Headphone output (volume adjustment OK) ⭕️ ・Game controller button operation ⭕️ ・Save function ⭕️ [Condition Notes] While there are few scratches for an item of this age, including the accessories, it is not a perfect item. There are scratches commensurate with its age. [Maintenance Details] We have brought together our know-how for maintaining retro PCs and game consoles over many years. ・Disassembly and cleaning of the main unit ・Replacement of all electrolytic capacitors on the main board ・Repair of deteriorated parts on the main board ・Board cleaning with isopropyl alcohol ・Disassembly, cleaning, and greasing of the moving parts of the CD-ROM drive ・CD-ROM drive focus/gain adjustment Considering that the lifespan of internal parts is about 10 years at the shortest, maintenance is essential to continue using it now, 30 years after its release. I think you can play it for 5 or 6 years, not just 2 or 3 years. Thank you for your consideration. #Yokomumu's PC Engine DUO Maintenance #RGB Output Added PC Engine DUO #PC Engine DUO
