Famicom and Disk System power on and function correctly. Verified by starting several games. This unit has been modified to connect via red, white, and yellow AV cables. It can be used if your TV has red, white, and yellow input jacks on the back. The included AV cable is a genuine manufacturer's cable, so unlike generic overseas cables, it is less prone to disconnection and is a sturdy cable. (See image) ※ The rubber belt has been replaced with a new high-quality belt used for repairing video equipment. Also, the head reading has been adjusted so that any disk can be read without problems. You can use it with confidence. ※ The top of the main unit has been repainted. This is amateur painting. There are also repair marks due to the painting. It is completely amateur painting, so it is not perfect. However, I tried to paint it carefully, layering multiple coats. ※ The front label is missing. ※ The directional pad on the controller has been adjusted to allow diagonal movements without stress. For example, the game character can spin around in place. ※ Both the Famicom and Disk System are USB powered. Working properly. (See images) However, when using an adapter that can accommodate two USB cables, the system did not boot when both were plugged in. (See images) ※ Adapter not included. If you don't have an adapter at home, you can purchase a 5V 2.4A USB power adapter at a convenience store or Daiso for 330 yen. ※ This unit has been confirmed to be working correctly. Returns are not accepted. Please understand this before purchasing. Thank you.
