If you are running a back up ROM on cart, the .sav file is just another file sitting there like the .nds file you threw on there to play. If you are running an original cart, you can either use an AR code to see it, or you can make a back up ROM of your game and look at the sav file. The AR code for the secret id is Google-able. Activate it and I think your money is your secret ID. The back up ROM process is lengthy I guess (never done it) but supposedly straightforward. Look here: http://www.drakx.org/?p=18#comments HTH.
