Is it possible to extract the save data from a retail DS game card into a .SAV file using a Supercard DSTWO? Or would I have to buy one of those "save dongle" things? If it matters, the game at the top of my list to get saves from is WarioWare D.I.Y., which uses a special save type that isn't used in most DS games; "NAND Flash". If the DSTWO can extract .SAVs, would it be able to properly extract all of the NAND Flash data? Thanks in advance for your help! 
Edit: In case this matters, the main system I'm hoping to use my DSTWO (I don't have one just yet) with is a 3DSXL, as of this writing on firmware "7.1.0-16U"; though I do have a DS lite and DSi at my disposal, but the DS lite won't play sound (the very tip of the end of a pair of headphones broke off and got stuck in there), and the DSi has a broken L or R button (I can't remember which), so while I can use one of them for things like updates and .SAV extracting if needed, I'll be actually playing games and such on my 3DSXL.
