What this patch tool does
Reserved Tool page for a future fully verified PlayStation Patch File implementation.
Format and input contract
No PPF file processing is enabled in Phase 20.
Integrity and compatibility limits
PPF 1.0, PPF 2.0, and PPF 3.0 differ in encoding/header/validation behavior; PPF3 can also include optional block validation, undo data, and a trailing FILE_ID area. A partial implementation would make a generic PPF Patcher label misleading.
Browser-local processing
When operational, Phase 20 reads only files explicitly selected in the browser, enforces bounded buffers, and does not silently upload patch inputs or outputs.
