I want to buy a Nintendo DS and buy a 2 Gig card for it. This is the website wich i want to buy it from: http://www.ombouwnederland.nl/shop/catalog...roducts_id=1142 Can i just download Nintendo DS Roms and put it on the card then play? Or rom games are only for the PC? If this is not true, do i have to download game's wich are not roms but other types of files? :/ Thanks.
