No operational check performed! The main unit and instruction manual are in good condition, but the box has minor issues. - Outer box (partially torn, but generally clean) - Main unit (clean) - Instruction manual (small wrinkle on the cover) (inside is clean) - Accessories (questionnaire postcard, warnings, etc.) Shipping via Yu-packet Post Mini. As described above, this is a complete set with all the main unit and accessories in good condition. However, I have not been able to verify its operation on an FC compatible machine (Columbus Circle). ~Added December 9, 2025~ I was able to confirm its operation on an AV-modified Nintendo Famicom!
