Nintendo 3DS Cobalt Blue - Included: Case, Charger I confirmed the operation using the Monster Hunter game I had. I was able to use it without any problems, including switching to 3D images, button operations, and touch operations. I used it with films on both the top and bottom screens. There are some scratches visible on the film. Just in case, I have left the films on. If you wish, I can remove the films to check the scratches. Cleaning has been done simply. Please note that fine dirt, such as in the gaps of the buttons, has not been removed. The data has been initialized. This is my first time selling a game console. There may be points that I haven't checked. If you are concerned, please refrain from purchasing. If you have any other questions, please feel free to comment. Thank you.
