# Galaxy on Fire 2: matching reconstruction of the Android Abyss Engine library

> Galaxy on Fire 2 reconstructs C++ for the Android game's Abyss Engine library, libgof2hdaa.so. Its NDK r18b build compiles ARM objects, links a shared library and compares functions and symbols with the original; notes record unresolved type and control-flow matches.

## Requirements & limits

- The original Android ARM32 libgof2hdaa.so is required for comparison.
- An x86_64 Linux host or an x86_64 macOS environment is required; Apple Silicon runs the toolchain through Rosetta 2. CMake obtains NDK r18b.
- The reconstruction remains a work in progress with unmatched functions.
