PC Engine CD-ROM² System Adapter AD-IF30 Since I don't have the main unit, I tested it by powering it on for about a minute with a Famicom (NES) compatible system that has the same DC9V voltage, but this does not guarantee functionality. Overall, there are scratches, small stains, and small dust accumulated in the grooves, indicating aging and deterioration. Please assess the condition based on the images provided, including the above-mentioned damage. It will be packed in a medium-sized cardboard box for Yu-Packet Plus shipping.
