After I did the system transfer (for the dsi downgrade) I realise that I forgot to backup my saves and NAND. I have all the files in my sd, is there any way to recover my Pokemon Moon save?

I can't because the 3ds is not reading the sd gamesUse JK's Save Manager?

Use FBI and reinstall Pokemon Moon, then try backing up possibly. Load the backup from one SD to the other.I can't because the 3ds is not reading the sd games
Insert the old sd on the "new transfered" console. Run jksv to extract the save. Install the game again on the "old" 3ds. Inject the save there.I can't because the 3ds is not reading the sd games
Thanks!Insert the old sd on the "new transfered" console. Run jksv to extract the save. Install the game again on the "old" 3ds. Inject the save there.
