What it is

Jedi Knight: Dark Forces II (1997) and its expansion Mysteries of the Sith were LucasArts’ first-person Star Wars shooters on the Sith engine, a 32-bit Windows program built around DirectX.

OpenJKDF2 “is a function-by-function reimplementation of DF2 in C, with 64-bit ports to Windows 7+, macOS 10.15+, and Linux” (OpenJKDF2 README). Its files are organised as closely to the original as possible, guided by symbols from a related game. DirectX dependencies are replaced with SDL2 and OpenAL.

FAQ

How do I play Jedi Knight Dark Forces II on Windows 10 or 11?

Use OpenJKDF2 with the files from your own copy (GOG or Steam). It is a reimplementation of the game in C with a native 64-bit Windows build using SDL2, OpenAL and OpenGL instead of the old DirectX code.

Does OpenJKDF2 include the game?

No. The README says it does not include any original game assets and that a valid copy of Jedi Knight Dark Forces II is required, available from GOG or Steam.

Does OpenJKDF2 play the soundtrack?

Yes. It plays the original soundtrack from Ogg Vorbis files, mainly as shipped with the GOG and Steam versions; disc soundtracks can also be loaded from a MUSIC folder.

Which platforms does OpenJKDF2 support?

64-bit Windows, macOS 10.15 or later (Intel and Apple silicon), 64-bit Linux and ARM64 Android, plus a 32-bit Windows build for older systems, and experimental Nintendo DSi, Dreamcast and WebAssembly builds. An iOS port is not started.
