Added

  • Firmware verification for ZIP archives and folders of loose NCAs using bundled fw/hashes/*.json size and SHA-256 references, without keys or extraction.

  • Firmware checks fetch current hash references from GitHub only for detected or explicitly selected firmware, with no disk cache and a visible bundled-reference fallback during outages. Repeated firmware checks fetch again; pure game folders make no request.

  • Automatic firmware detection in folder integrity checks, firmware version/result details, and CSV export. Missing, changed, extra and duplicate NCA entries fail verification.

  • Selectable title metadata sources: Tinfoil, regional GitHub TitleDB with persistent offline cache, and configurable NLib API.

  • Firmware mapping for master-key revision 0x16 to 23.0.0. Its CRC32 reference was derived from a local key file and is not an independent upstream confirmation.

  • Added validation results for prod.keys and title.keys to the settings window.

  • Added detection and reporting of missing master_key_XX revisions in outdated prod.keys files.

  • Added CRC32-based validation of known master-key revisions through master_key_16.

  • Added malformed-line detection for key files.

  • Added structural validation of Rights ID and title-key pairs in title.keys.

  • Added an estimate of the newest supported firmware based on the highest valid master-key revision.

  • Added a warning when a key file contains a newer master-key revision that this application version cannot validate or map to a firmware.

  • Added localized validation messages for English, German, French, and Spanish.

  • Added automated tests for key-file validation, firmware mapping, and unknown master-key detection.

  • Added anonymous FTP support to the existing HTTP/HTTPS key downloader.

  • Added editable default Sphaira FTP locations for prod.keys and title.keys; customized addresses continue to be stored in the application settings.

  • Downloads now use a temporary file and only replace the destination after a successful transfer.

  • Added parsing of main.npdm from program NCAs.

  • Added a program-security assessment based on signed ACID file-system permissions, including safe, unsafe, and dangerous classifications.

  • Added the ACID signature state, raw permission mask, and authorized service list to the program details.

  • Added base title ID, required master-key revision/key generation, minimum application version for DLC, and NCA distribution type to the title overview.

  • Added package-structure detection for Scene releases, CDN rips, converted packages, Homebrew packages, and incomplete NSP/NSZ/XCI/XCZ files.

  • Added package file size and an estimated NSZ/XCZ compression ratio with reconstructed uncompressed size.

  • Added detection of the system-update version contained in an XCI/XCZ update partition.

Fixed

  • Solid NCZ reads now cache the decoded prefix in a temporary file, avoiding complete decompression restarts on backward/random reads and improving the likely bottleneck behind issue Myster-Tee#52.

  • Block NCZ decoding respects compressed block boundaries; block lookup, short reads, EOF handling, zero-length reads and disabled caching are corrected or covered by regression tests.

  • Online rename failures (including HTTP 503) fall back to the local NACP title when available.

  • Unrecognized additional key names are reported as localized informational notices; malformed key data remains a warning.

  • Prevented a double release of the LibHac main.npdm file while loading program-security information.

  • Added a defensive size limit so malformed NPDM files fail safely instead of destabilizing file loading.

  • Snapshot NPDM security data inside the protected parser block so UI bindings cannot trigger delayed parser failures.

  • Batch preview errors no longer replace otherwise valid package and integrity results with Unknown.

  • Exception details and stack traces are now included in the application log for actionable diagnostics.

  • Fixed a crash when the program-security fields were displayed by explicitly using one-way WPF bindings for read-only values.

  • Batch integrity results now include the underlying NCA error and identify broken NSZ/NCZ Zstandard streams as corrupted or incomplete compressed data.

  • Batch integrity results and CSV exports now include the detected package structure.

Notes

  • ZstdSharp.Port remains at 0.8.8; compressed NACP titles remain supported.

  • Firmware references ship with the application and work offline. ZIPs repacked with different compression are valid if all NCA contents match. Local /test/ data is excluded from Git.

  • Validation: solution build and 94 automated tests (including nine firmware tests). Real firmware archives were not used for these tests.

  • The firmware shown for prod.keys is the newest content firmware supported by its keys. The exact firmware on which the file was dumped cannot be determined from the key file.

  • title.keys can be checked for valid structure, but title-key values cannot be compared against a universal list of expected values.
