I haven't made any modifications. Operation has been confirmed. There are no issues with the Joy-Cons. The included accessories are the dock, HDMI cable, Joy-Con charging stand, and Joy-Cons only. Everything works fine, but there are scratches on the back of the main unit. Please refrain from purchasing if you are concerned about the environment of use, as it was used in an environment with electronic cigarettes. I will clean it.
