NDS games help.

[ShadowsServant]

Hi all,
I would like some help.
I just bought a Personal Media Player for the Nitendo DS/DS lite.
The thing is I can't make it play any of the games I've downloaded.
It has a drag and drop system, when I put in the cartridge in the DS and open the file, it's empty.
It won't recognize any of the nds games....On the box it clearly says it can play games, videos and music. I'm disappointed.
Here is what the product looks like: http://www.nextag.com/DATEL-Personal...35/prices-html

If anyone can guide me so I can actually play some games on the blasted thing it would be greatly appreciated.

Thank you for your time.
ShadowsServant.

I returned the damn thing, turns out it could only play copyrighted material. Go figure.
That was a total bust.
