While the base engine does not use checksums (CRC32/MD5) to validate save files, developers implementing anti-cheat measures often inject scripts that calculate a hash of the save file. If the file is modified and the hash is not updated, the game detects tampering. An advanced editor must identify these scripts in the game's source code and recalculate the valid hash.
