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?
