[REQUEST] "movies.arc.sig" file for Nintendo 3DS Movie Player

Morning' guys !
Today I'm asking for a little thing, and hope that someone will be able to help...

First, a brief description of the item itself: The "Movie Player" is a not-for-resale Nintendo 3DS cartridge, which was produced in october 2011. This cart is not a game, and more acts like an app. Nintendo used it to run videos directly on the console's screens, mostly during the original Nintendo 3DS launch.
Few stores had them in the early months. The video was just launched, and then the console placed behind a glass just for the public eyes. Then it was abandonned little by little, for more interactive demos in kiosks. If you're curious, a rom of this cartridge was also released ages ago (but without more infos about its usage).

Now, according to recent documentions posted online, we know that the console needs a certain "movies.arc.sig" file placed on the console SD card. Put it in your console, insert the Movie Player cart, and boot your console up. The sig file should being read and the video imported, ready to play.

Since I don't have any Nintendo's rep in my friend list, I really hope that someone here do have this kind of file. The video in it doesn't matter. Thanks a lot for any help / info / files you can find!

 

Also looking for this!

 

I have this card. Also I am looking for any content. In the cartridge there is a very interesting feature - Auto-startup application when the console is turned on

 

You can also find the auto-boot feature on the EUR OOT 3D demo card and probably other demos too.
