PS4PKGViewer v1.6.6 — ChayahLabs List Contents Size Accuracy Update

PS4PKGViewer v1.6.6 — ChayahLabs List Contents Size Accuracy Update

This maintenance release improves List Contents size accuracy while preserving the original PS4PKGViewer behavior wherever possible.

What's new

• Fixed affected compatible PS4 Fake PKGs whose Image0 files could incorrectly appear as 0 Bytes.
• Existing non-zero List Contents sizes remain untouched.
• Zero-size files are corrected only when the exact inner-PFS path proves a logical size greater than zero.
• Genuine zero-byte files remain 0 Bytes.
• Corrected Properties > Decrypted-size from the final file list.
• The corrected aggregate is recomputed from the final PkgCabinet state, making repeated execution idempotent.
• Added in-memory PFS-size caching for fast repeated List Contents access.
• The size fallback is read-only and silent; if the PFS metadata probe cannot inspect a package, the previous Viewer behavior is preserved.
• Moved the PFS size-probe runtime into ChayahLabs.Runtime to keep the portable release root clean.
• Retains all v1.6.5 ICON0 compatibility work and v1.6.4 compatibility improvements.

Validation

• Hulu / CUSA00131: 11 false zero-size files corrected.
• FPKGi v1.10.0: genuine zero-byte Media/boot.config preserved.
• CUSA49956 sample: 157 false zero-size files corrected.
• WatchESPN / CUSA05214: existing valid sizes preserved.

Portable distribution

Keep ChayahLabs.Runtime together with the Viewer. PS4PKGViewer.bin is not distributed; it is generated locally as user configuration when needed.
