Is doing something like this possible with that Save Data Filer program? I'm essentially interested in doing the reverse of the official save data transfer tool. Example: I own a game on a cartridge, then buy the eShop version a while later. I use save data transfer to get the data over to that version. After playing for a while, I decide I want to use Powersaves to give myself more items/money/whatever in my game. But obviously you can't use Powersaves on eShop saves. So assuming I still have the cartridge (which I do for some titles like Pokémon), it would be super convenient if I could reverse the process so I could use Powersaves, then save data transfer again. Is such a thing possible yet? I haven't had a chance to try any of this since I'm temporarily without a 4.x 3DS.
