NEC PC Engine Core Grafx Works perfectly. I have confirmed its operation using my own software. Button operations work without any problems. Instruction manual is missing. The AV cable is not original, but it is new. The outer box is faded, but the main unit is in good condition. Please understand that this is a used item, and purchase accordingly. #PC Engine #Core Grafx I apologize, but to avoid any trouble, I do not allow holds on any of the items I am selling. Also, due to work commitments, it may take a little time to ship the item. Thank you for your understanding.
