Pac File

You can use the GUI/Graphical version, or for the command line (CLI) commands:

• Unpacking all files from a pack: FF16Tools.CLI unpack-all -i <path_to_pac> [-o <output_directory>]
• Unpacking a specific file from a specific pack: FF16Tools.CLI unpack -i <path_to_pac> -f <game_file> [-o <output_directory>]
• Unpacking all packs: FF16Tools.CLI unpack-all-packs -i <path_to_folder_with_packs> [-o <output_directory>]
• Pack a directory into a .pac: FF16Tools.CLI pack -i <path_to_directory> [-o <output_directory>]
• Listing files: FF16Tools.CLI list-files -i <path_to_pac>

Textures

• Converting .tex to .dds: Drag-drop files/folders or FF16Tools.CLI tex-conv -i <path>
• Converting to .tex: Drag-drop files or FF16Tools.CLI img-conv -i <path>

[!WARNING]

• 3D textures are not yet supported.

Nex (NXD)

• To SQLite: nxd-to-sqlite -i <path to directory> [-o output sqlite file]
• From SQLite: sqlite-to-nxd -i <path to sqlite file> [-t <table_list_separated_by_spaces> -o <output_directory>]

[!NOTE]

• When converting from SQLite to Nex, you can provide a table list to avoid converting all the tables if not needed.
• Use a SQLite database editor/viewer such as SQLiteStudio.
• Always check the Changelog for updated table column names.
• Refer to the table layouts here for the column value types. Note: this has been mapped mostly manually. Please contribute if something is amiss or you have figured out the column names.
• Nex can contain nested data, therefore arrays and other structs are converted to json strings.
• Nex can contain row sets that don't actually contain any rows. This information is lost between SQLite conversion, but should hopefully not matter.
• You may need to edit root.nxl from 0001 to reflect the number of rows (if you've added/removed any).

Modding

Method 1: Automatic Mod Loader

Use Reloaded-II and install the FFXVI Mod Loader.

Refer to this.

Method 2: Modding Manually

[!NOTE] You should use Method 1 if you intend to distribute mods, otherwise it is not possible for users to install multiple mods that edits the same pack contents.

You may choose to rebuild a .pac entirely, or preferably you can use .diff.pac files.

When packing an extracted folder, the output pack file should have .diff in its name. The game will load this file.

So if your files came from 0000.pac, the new pac file should be 0000.diff.pac.

[!IMPORTANT] You only have to include files you want to edit, not ALL the files from the original .pac.

If the extracted archive had a .path file, it should be present when packing.

If you are editing any of the language files (like 0001.en.pac), you should have 0001.diff.pac AND 0001.diff.en.pac. if you don't have the first one, the second one won't load. If you don't need to edit the first one, just copy it and rename it.

Extra Notes

Each pack file can contain a general embedded folder name. This is the case for 0001.pac, or nested packs inside 0000.pac.

For instance, 0001.pac has nxd has its embedded folder name. Which means that every file in that pack is inside a folder named nxd. Example: ability.nxd becomes nxd/ability.nxd

This can be tricky to handle, so the unpacker creates a .path file with the name of the folder.

The packer picks the path from this file accordingly. It can also be set manually with the --name argument, if needed.

NuGet

• FF16Tools.Pack
• FF16Tools.Files

Building

Requires .NET 8.0 (VS2022), Windows, DirectStorage support.

Format Documentation

• 010 Editor Templates
• C# Classes

Roadmap

• Return building/unpack progress
• Find a GDeflate library that actually works cross-platform

Discord

Acknowledgements

Vortice.Windows for having a usable DirectStorage wrapper/API.

• GisDeflate would break on a certain file (also doesn't have span interfaces),
• Silk.NET has 0 documentation, and would return obtuse windows errors such as 0x8004001 (not implemented). Very useful!
