How many Nintendo ds games would fit on a 2GB memory stick?

I've seen an ad selling: "Nintendo Ds R4 Card with 2GB mem Stick and 500 games which includes: R4 TF Micro SD Adapter; USB MicroSD card reader/writer; Protect case; Manual CD; all for $70. Is this a good deal? Can 500 games really fit? What questions should I ask if I were to purchase? Thanks in advance for you... show more I've seen an ad selling: "Nintendo Ds R4 Card with 2GB mem Stick and 500 games which includes: R4 TF Micro SD Adapter; USB MicroSD card reader/writer; Protect case; Manual CD; all for $70.
