I just wanted to ask, if there is someone who know something about this:

In a frensh forum, there is a user who bought Pokémon FR Diamond version (eBay...). Now his problem is, the game ID is ADAJ-B714D00B instead ADAF-F23BEADC, so no one code works.
I thought that it could be an updated version, but it's a lil bit strange. ADA->J<- means that the gam is in japanese, right? Could it be a fake version?

Ty.
