Just tried it and can confirm Kasumi's results. It makes me calibrate the screen, choose a language, name, date, time, and birthday. All the stuff that you do when you turn on a DS for the first time. Then it tells you it needs to shut off to save the settings. This transitions into the 3DS' 'power off' screen. I tried both pressing the home button and turning the 3DS off. In both cases when you turn the 3DS back on the firmware will ask you to go through the same process again. You can't get to the DS' menu to play Pictochat.
Exactly!
I might put a video of what happens soon!
