A Fallout 4 Script Extender plugin that adds support for the new BA2 archive format introduced in NG update 1.10.980 to versions 1.10.163 and older. Fixes crashes, similar to Backported Extended ESL Support for Skyrim Special Edition.

• CMake and vcpkg are expected to be set up beforehand. Visual Studio 2022 is recommended.
• <preset> is f4se.
• <build_preset> is f4se-release or f4se-debug.

git clone --recurse-submodules https://github.com/Nukem9/fallout4-backported-archive2-support.git
cmake --preset <preset>
cmake --build --preset <build_preset>

• For developers, edit CMakeUserEnvVars.json and set GAME_ROOT_DIRECTORY to Fallout 4's root directory. The build script will automatically copy library files to the game folder.

• For manual F4SE installs, place BackportedBA2Support.dll in the corresponding Fallout 4\Data\F4SE\Plugins folder. An example path is: C:\steamapps\common\Fallout 4\Data\F4SE\Plugins\BackportedBA2Support.dll
