Upon trying to restore my missing Pokemon sun save, the game tells me that the "save data is not compatible with this version." I have a backup from several months ago that I tried to restore, but I had multiple save files I was using for different ROM hacks. Having not tried to restore it before, I don't know how to fix my save file.
I have read that there is some sort of protection against save restore using 'secure values,' and that I need a current save backup to get the secure value (as far as I understood it anyways) so would creating a new file, backup up the save, and then fixing the secure value restore my save? All I really want is my Pokémon from the save, not the actual save, but I can't figure out how to open the file to extract the 'mons without first restoring the save. I tried using PKSV to access the data, but all of the boxes show up empty.
How can I extract my Pokémon from an old savegame [or] How can I restore an 'incompatible' save?
