This is a save NOT a game. This is a max super starter save. 

ALL WEAPONS/SHIELDS/BOWS HAVE INFINITE DURABILITY.

What you see is what you get.

For the Master Mode Save, all costumes obtained (check house at Hateno), near all max upgrades on costumes, all shrines done, all korok seeds obtained, all divine beasts beaten, all photos obtained, and all main quests/side quests done.

You are getting two saves with this.

To get this onto your Switch you'll need to go to your Cloud. 

System Settings > Select Data Management > Save Data Cloud Backup> Choose BOTW and backup and save data. Please turn off auto backup/download once this is done.

After I am finished you can go to the same option but now press Y to update to get the new save.
