This is too complicated, i'm just wondering, can i get a .CIA with my save from CFW AND use that same .CIA with my own retail save on my Gateway emuNAND?
Sorry, did not understand what you are saying.
okay it's not that complicated, as I finally got it to work.
It's just a pain in the ass to execute cause CFW is buggy.
Here is how I got it to work:
1. Have different SD cards
Use a different SD card for CFW.
2. Install CFW.
I followed "Part 2" of the steps here:
http://gbatemp.net/threads/tutorial-4-5-sysnand-4-5-cfw-9-4-emunand-without-gateway.378721/
Except that I did not install devmenu/bigbluemenu.
I
ONLY installed savedatafiler that works for CFW.
3. Use SDF to backup retail carts
Once in CFW, I insert retail cartridge, and back up the user save. (bottom screen, left tab, top most option (might read as "CTR"))
If need to back up more than one cartridge, exit SDF -> change cart -> enter SDF
4. Insert CFW SD card onto PC, and copy the entire "FILER" folder
The root of the SD card, should have a folder called "Filer".
copy it, as it contains all the backed up, decrypted saves.
5. Paste "Filer" into GW SD card, and import the saves!
Enter Savedatafiler on GW.
bottom screen, third tab.
It will show a list of entries, which the last values are usually the title id.
(Example user: <some values> :
00000308<- the underlined values are the title id. this example is mario kart)
when you move up and down on d-pad, different items will be highlighted.
To import the save to the cia game, just press R+A (import this user save data to SD Card)
I got my Asphalt 3D progress transferred over, like finally!
Note: I made my Asphalt 3D cia to have the correct save size (128KB).
Not sure if this will affect importing, if save sizes are different.
Probably not though, as I assume SDF will encrypt to fit the correct size..?
