I bought Ruby cause I liked Groudon and it was the popular version IMO.
I bought Pearl cause I liked Palkia and it wasn't the popular version IMO.
I am buying Heart Gold because I like Ho-Oh and it is the popular version IMO.

Looks to me like it is the demo from a store and the big blue cable is the security cable.
