Let's walk through a typical modding scenario. We'll use a fictional game called "Adventure Quest" that uses a JSON save file stored in %USERPROFILE%\AppData\LocalLow\CoolGameCo\AdventureQuest\savefile.json . unity save edit

// A single instance for easy access public static SaveManager Instance get; private set; // Save the updated data EditorUtility

// Load the saved data file = File.Open(Application.persistentDataPath + "/playerdata.dat", FileMode.Open); PlayerData loadedData = (PlayerData)formatter.Deserialize(file); file.Close(); Early versions of Vampire Survivors used a plain JSON save

A checksum is a digital fingerprint. When a game saves, it calculates a hash of the save data and appends it to the end of the file. When the game loads, it calculates the hash again. If you changed your gold from 100 to 99999 , the hashes will not match, and the game will reject the save.
