Very first post:hey have read a few pages here but I do not really understand how I can get the films in my 3ds. what program do I play them and how do I install it?
Put the sd card back in your 3ds and start the 3ds-camera application. There you'll find the videos....Ideally, plug in your SD card and choose the folder on it containing any photos/videos taken with the 3DS camera as the output folder, and then you won't have to manually copy any files.
