Decompress / compress the SQLite database embedded in a Hogwarts Legacy GVAS save file.
Multiplatform rewrite of topche-katt/hlsavetool.
All windows.h / WinAPI / MSVC-only code has been replaced with portable C11.
| Platform | Library file |
|---|---|
| Windows | oo2core_9_win64.dll |
| Linux | liboo2core.so |
| macOS | liboo2core.dylib |
The Oodle runtime cannot be redistributed, but pre-extracted native builds are available here:
https://github.com/new-world-tools/go-oodle/releases/tag/v0.2.3-files
Download the file matching your platform and place it in the same directory as the
hlsaves executable (or anywhere in your PATH / LD_LIBRARY_PATH).
