3DS Recorder 1.1.0 records the whole 3DS with Luma3DS, sends it to your phone and adds a 30-second Replay
3DS Recorder records both screens and the sound of any game or the HOME Menu on a 3DS with Luma3DS, turns the video into an MP4 on the console and sends it to your phone over Wi-Fi. It left beta on November 13 and 1.1.0 adds Replay, which saves the last 30 seconds.
