Hacking Problems with Etrian Odyssey 2 Untold save backup/transfer

[Aroth]

So it seems Etrian Odyssey 2 Untold does something strange with the save data and it prevents transfers or backup/restore.

I was using a scene rom and decided to buy the game so I could use it with Powersaves, then went to transfer the .sav file to the cart and upon boot it said "deleting corrupted save data".

At first I thought maybe it had something to do with the rom having a null header so I started a new game on the cart and backed it up, then backed up the cart and moved it to my GW sd card (renamed .3dz too). When I loaded the newly created rom (with my unique header) and tried to load the save from the backup i just made (using the same unique header) I still got the "deleting corrupted save" message. I suspect the game uses the contents of the extra data it puts on the sd card to verify the save and if they don't match it declares it "corrupt".

EDIT: NVM I figured out what was wrong... feel like an idiot for not realizing it beforehand. Anyone know if a way a was ever figured out to use 6.0.0+ retail saves in GW mode?

If you have a console/friend with console/whatever means with 6.X+ then run the game on there, use SDF to get the decrypted save and import it on the older firmware console then that might do it.

Oh hey, I did the same I used NTR to transfer the save easily. How're you enjoying it?

My only console capable of using anything is a N3DS XL with 9.0 Sys and 9.4 Emunand. Only ever used GW, so I'm not entirely sure how to go about using SDF (I know I can't use it with GW because SDF only loads in GW Mode and retail carts only load in Classic Mode.)
