This download contains nothing from Halo 2: no game files and none of the game's program code. The recompilation is made on your PC from your own copy of the game.

How it works

  1. Unzip anywhere you can write to (about 10 GB free) and run OpenHalo2.exe.
  2. Choose your Halo 2 disc image (Redump .iso / XISO) or the default.xbe of an extracted copy. It must be the original retail disc.
  3. Open Halo 2 lifts your copy of the game's program into C, checks the result against the code this release was tested with, and compiles it with the bundled LLVM clang. This happens once and takes about 10–30 minutes.
    • Compiling needs Microsoft's C runtime and Windows SDK libraries. If Visual Studio or its Build Tools are installed, those are used. Otherwise the build asks you to accept Microsoft's licence and downloads them from Microsoft (about 85 MB) with xwin.
  4. The game starts. Always start it through OpenHalo2.exe.

Gameplay is the same as 0.1.0, which has been withdrawn because its program contained recompiled game code.
