I've recently acquired a DSiWare title and was looking to have a little fun hex editing the save. Looking through the forums and using Google, I know that DSiWare saves are stored in TWLNAND and have located the data folder holding the save.
My question is: Is there anything special needed to dump and inject the save other than copying and pasting it from NAND to SD and back again? All the threads I found were from long before FBI 2.0 came out with the ability to access files on NAND and while I can make changes and still load the modified save in the game, none of the changes I made show (or I'm getting the offsets wrong). Also, some data I expect to find in the save is not there, so I'm thinking it may be encrypted in some way?
