While Ubisoft eventually released Version 1.06, many core community mods were built strictly for the v1.05 framework. Version 1.06 introduced multiplayer lobby changes but accidentally broke several single-player scripting hooks and user-interface mods. Therefore, obtaining the original "Patch 72" variant of patch.dat and patch.fat is the definitive way to achieve a stable baseline for heavy modification. Why Players Hunt for the Original Files
Why has the number "72" become a colloquialism for these files? In the community, it is often associated with the file size (often roughly 72MB in compressed form for the primary patch payload) or an internal versioning header visible only via a hex editor.
In the context of Far Cry 3 , the patch.dat and patch.fat files are hierarchical. They do not contain the core engine executables; rather, they contain the "patch" data that overrides the base game files located in common.dat . This system allows developers to push updates without forcing players to re-download gigabytes of static data. The "72" identifier likely refers to the internal build number or the file size characteristic of the original release, distinct from later versions that patched in features like Far Cry 3: Classic enhancements or removed licensed music tracks.
The phrase is typically associated with a specific mod or "repack" configuration often found in community forums or file-sharing sites. These are the actual data containers
The patch.dat file can be quite large (often over 200 MB), as it contains all the modified assets from various post-launch updates. In contrast, its index, patch.fat , is relatively tiny (often just a few kilobytes in size).
When you see patch.dat and patch.fat in your game folder (usually located in bin or data_win32 ), these are the files the game reads to "overwrite" the original game data. If you want to change how much damage a Shredder SMG does or remove the HUD, you modify these two files. The Significance of "72" (Version 1.05)
Some older mods specifically require files from because the v1.06 update (released years later) changed the way certain files are handled. If a mod crashes your game, you may need to use a v1.05 restoration guide to replace your patch.dat/fat with the older versions.
If you made a backup before modding (which you should always do), simply copy those original files back into the data_win32 folder. Introduction to Modding with Patch Files
