Picked up a DS demo today, but is it legit?

[Mattiekrome]

I was at Gamecrazy earlier today and noticed that they had a "Magical Starsign" with the NFS label on the back. I could tell there was something different about the label from the second I saw it, but just couldnt put my finger on it (The DEMO GPK line). I decided to go ahead and pick it up anyways, so my question to you demo collectors out there, is this a legit Nintendo demo, or is this a NFR label that somebody made in their basement? Its a pretty professional looking label if it is a homemade one

And here is the back next to a few of my other DS demos... (Sorry for th size, I hope it doesnt stretch the screen too much, but the detail goes all to hell if I shrink it down anymore)...

The magical starsign is not a demo, but rather a promo copy of the full game given out to certain employees (I believe only managers recieved it and it may have only been at game crazy). If it says demo on the back white label, its a demo. The sticker is, of course, legit though.

Are DS Demos worth picking up as of now?

I know of a local store that has the Meteos demo. It has the DIS- line before the rest of the code.
