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.

Extract the complete folder and run:

PS4PKGViewer.exe

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

The release archive is a true RAR 4.x archive with a native archive comment, verified for PowerArchiver-style compatibility.
