Do you mean dumping? You can try to use Rudolph's Wifi tool or Rudolph's Slot-2 tool which can be found in our download center. If you are going to use the Wifi tool, you must download small-ftp (I always use it when I dump Nintendo DS games). You can download small-ftp here. So extract the zip archive somewhere and run the exe file. Now go to Settings >> General and change FTP-port to 8080. When that's done you go to Advanced and tick off 'use local IP'. Now go to users and add a new one by clicking 'new'. Choose an own login and password. After you did that, choose the directory where you want to have the nds file (normally on your hard-drive (C:)). Permissions are LRW. So you're done now. Open the ini file which is in the folder of Rudolph's Wifi tool and edit it. The login, password and port must be the same as the ones on the ftp. Save it, start small-ftp, start the nds file on your flashcard and choose the option you want. Don't ask me how to do it with a Slot-2, because I don't have one.
