I traded for the Sonic Shuffle that came with the Sonic DC bundle back in 2000 (2001? it seems so long ago!) The person let me know that it has a UPC instead of the NFRS note, but it came with the system.

I have no reason to doubt the person, and I planned on comparing the instruction manuals when I got it (everything else looks the same as the shelf version). Well, the problem is, I didn't look at my copy. It's still sealed, and I'd rather not open it. Does anyone have both the version that came with the system and the retail version that can compare and tell me if there are any differences?

I've got a complete collection, now I'm going for the packaging variations.
