Does anyone have a copy of Metroid Prime Hunters for the DS...

that they bought new, but opened up?

I recently bought a supposedly new copy from an Amazon seller recently and opened it up today and notice that there is a glossy "discoloration" (It looks like it could be a stain) next to the gba game holder inside the game case; I couldn't take a picture of it, but I edited a ds case picture I found online to show where the discoloration (See below). The area I am talking about it outlined in yellow.

My DS is being repaired so I can't check if the game cartridge has any old files on it until I get my DS back.

But, I've had problem with marketplace sellers passing off used games as new before. And since I overpaid for this game, I want to make sure I didn't get ripped off (I know there is probably no 100% surefire way to do this, but I can try).

Could anyone with a copy of this game take a look at there's just in case this is just intrinsic to the case itself? Thanks!

What kind of plastic was this supposed new game wrapped in? Resealed games tend to have a very different type than a factory sealed game, that would be the first thing I'd check. If you haven't thrown it out yet, try to get another sealed DS game and compare the the two plastic wraps.

It had the Y-fold seal, but I have purchased at least one other game before that had the Y-fold seal, that had old saves on it.
