PS4 Save Validator

The PS4 Save Validator provides deterministic validation of PS4 save data across multiple titles and regional formats for QA, development, and backup workflows. It analyzes the save file header, computes core hashes, and checks consistency against the selected title and region. Users supply a save_file, a game_title, a region, and a firmware_version; optional inputs enable deeper checks against known-good hashes or cryptographic signatures. The tool outputs a structured validation report that highlights pass/fail status, checksum values, detected issues, and actionable remediation steps. It is designed to integrate into automated QA pipelines and supports export in JSON or CSV formats for traceability. This approach helps teams quickly identify corrupted saves, tampering attempts, or mismatches that could cause load failures or progression loss. The validator emphasizes determinism and repeatability, ensuring identical inputs yield identical results across environments. It does not perform decryption or bypass console protections, and relies on locally available references to avoid privacy concerns. Unique value comes from cross-title and cross-region consistency checks, which catch subtle tampering patterns that single-title tools may miss. Typical use cases include regression testing of save-related features, migration verifications after firmware updates, and validating backups before archival. The tool is compatible with NA, EU, and JP save formats and uses standard region codes, enabling consistent reporting across teams and regions.
