The Bigs might be fake.
the artwork is horrible with the main title logo covered up everywhere.
I don't think a commercial release would be that bad (still possible though).
Since Madden is fake i wouldn't surprise me if his was fake too.
madden 07 is fake or its a burnt copy intended to play on a modded system.
the bottom white curve is a dead give away that it uses a custom printed cover.
none of the commercial releases (at least that i have in th U.S.) have that curve.
Also, there is no ESRB rating on the disc.
Unfortunately i think you may have gotten jipped!
edit: I typed "DVD ROM D9" into google and it had a bunch of links describing it as a type of backup disc.
Which confirms that they are indeed fakes.
