evandixon what do you mean by that? I have checked in my "Battery" folder and there are no .sav files in there. If you mean to make a .sav file I did, edited it, then tried to import it back in to Desmume and the import failed (I checked various options on the import screen and they all failed, even the 512bit option which was the size of my file). Could my ROM be bad, idk what is wrong at all.
