ok i know there is a thing for the nds to play many games on it idk what it is called it's like a memory thing but idk if u know what i am talking about just tell me what it's called and where can i get it

edit: topic title revised - gamecop

I think you are talking about flashcards. Buy one online.

Just Google "R4 DS" or "M3 Simply" or "SuperCard DS One."

ok i found it but wihch one is better and cheap because i don't have a lot of money to waste but i want to find something good.....i was looking at the super card lite and with the key thing but idk how would i be able to put games in it i don't see the connection thing or it doesn't even come with it
