Hello

Im not sure what I need to buy or were to get to downlaod DS games can someone let me know.

Are you trying to say you want the games you download from here on RomUlation to go in your DS?If so, you'll need something called a Flashcart, go do a google search on something called CycloDS Evolution, that's the best Flashcart everyone here on the forum agrees upon as being the best of its kind ;)
