Unpackers
- Main article: PAK file format.
These tools let you explore and/or unpack the .pak files containing the Arx Fatalis game data. Resource listings for all known editions of the game are available in the ArxFatalisManifests repository.
arxunpak
Arx Libertatis comes with the arxunpak command-line tool to unpack Arx Fatalis .pak archives.
You can run arxunpak without arguments (for example by double-clicking the executable) to unpack all resources to the unpacked subdirectory of the Arx Libertatis user directory, for example %USERPROFILE%\Saved Games\Arx Libertatis\unpacked on Windows or ~/.local/share/arx/unpacked on Linux. If you installed the Arx Fatalis data at a non-default location you might need the --data-dir option to point to the directory containing your .pak files.
arxunpak will only extract those resources seen by the game - for example the old scripts in data.ṗak are hidden by the patched scripts in data2.pak. To access the unpatched resources specify the archive to extract as an argument to arxunpak:
arxunpak data.pak
More information is available using the --help option and in the man page.
ArxPak
ArxPak is a GUI tool to view and extract the contents for Arx Fatalis .pak archives.
Note: When you specify a directory to extract data, the program will actually place all files in one directory above (on the same level as the specified directory).

It was the de-facto compression for games from around Y2K, like Arx Fatalis

arx-header-size

This is needed, because the files are partially compressed and this number can be given as an offset for node-pkware

Debugging
Arx Libertatis script console
- Main article: Script console.
Arx Libertatis 1.2 and newer comes with a script console that can execute any command supported by the Arx scripting language. Make sure to use the latest development snapshots.
In debug builds and development snapshots the console can be opened using a configurable hotkey (` by default).
In release builds the following cheat spell opens the console:
Aam Mega Stregum Comunicatum Spacium (create increase magic control field)
You do not need to have the runes to cast this spell. Casting the spell once unlocks the console, after which it can be opened using the normal hotkey.
Arx Libertatis debug views
- Main article: Debugging.
Arx Libertatis 1.2 and newer comes with several debug information displays and views that can be cycled through with the F11 and Scroll Lock keys. Make sure to use the latest development snapshots.
arxsavetool
Arx Libertatis comes with the arxsavetool command-line utility to view, extract and modify Arx Fatalis and Arx Libertatis .sav archives. The following actions are supported:
Extract all save data to the current directory. This will create one file for each entity named after the entity ID, one lvl* file for each level (that you have visited), one player file, one pld file and one globals file. See the wiki page describing the save file format for what these binary files do.
arxsavetool extract <savefile>
Add one or more files to a .sav archive. If the file already exists in the archive it is overwritten.
arxsavetool add <savefile> <files>...
Fix save file errors (fixes problems caused by bugs in old Arx Libertatis versions - back up your saves before!):
arxsavetool fix <savefile>
Change the in-game name of a save file:
arxsavetool rename <savefile> <newname>
View save state:
arxsavetool view <savefile> arxsavetool view <savefile> <ident>
where <ident> is pld, globals, player, lvl followed by a 3-digit level number, or an entity ID.
For all commands, <savefile> is the path to a .sav file or a directory containing a gsave.sav file.
If you installed the Arx Fatalis data at a non-default location you might need the --data-dir option to point to the directory containing your .pak files. More information is available using the --help option and in the man page.
