It's a long story ... I corrupted my save by extracting a .sav file from the sky3ds flashcard, and when I put it back in, I got the typical corrupt starting error when using a save that is not my own. Later I reintroduced that .sav and injected it with JKSM to re-extract the main file, which is the one I have here.
I can open the main with the PKSM but everything appears unchangeable and the application crashes. That was the last hope I had of not having lost all the information.
Is there a program to decrypt (or something similar) the file? Simply looking at the pokemon information I had is enough.
thank you very much for answering me so fast!
