This is a Family Computer commemorating the 50th anniversary of Jump! I've confirmed that all buttons work without any issues. I've also confirmed that it powers on, as shown in the fifth photo. All accessories (including the controller, the main unit, HDMI cable, USB cable, and instruction manual) are included, so you can start using it right away. I haven't used it much since I bought it, so the condition is quite good, but since I'm just an amateur, if you're particular about condition, please consider carefully before purchasing.
