DS downloadable play is pretty much where you can download what another person with a DS has, you can use wireless conection to play games with another person with a DS, It's a cool system! You need to have some one else with a DS to use DS downloadable play, you need you or the other person to pick the option on your game, then the other person to wait with the connection by picking DS down loadable play button. (Sorry if my spelling or grammer's wrong, I'm tired! XD)
