Can you add hearts or stamina to your save editor the online one doesn’t allow for thisThanks a lot for this. I'm pushing the update for this as soon as I'm finished. Until more saves from varying game versions is available, I only can guess the game versions based on existing source code (The current assumption seems to be that your save is from v1.3.0 of BotW). After I update it, my program will instead try to guess it, if it fails it will ask the user if they want to use it anyways and then if so convert it.
EDIT:
I will also not be adding save editing as the online save editor I was going to port from anyways already supports Switch saves. It seems pointless in my opinion to remake something that already works fine
