I edited my Shield save file with pkhex and injected it back with Checkpoint on my emuNAND. After this the game always froze when starting. As I did not have a backup of the save file, I deleted the game data in the Switch settings. However when I start a new game, it keeps freezing when I reach the point where I can move. Any ideas how to fix?
Edit: found the backup in the bak file, injected it and still not working. Used different saves, it's still freezing everytime. I think something messed up my NAND, will rebuild the emuNAND tomorrow.
How is this possible? How can a save file injection corrupt my emuNAND?
