WING COMMANDER UNIVERSE
A modern reimplementation of Wing Commander: Privateer, built around the original game data, authentic behavior, portability, modding and long-term preservation.
ABOUT THE PROJECT
OpenPrivateer brings the original Wing Commander: Privateer to modern systems. It uses the original game files and aims to recreate everything from spaceflight and combat to missions, conversations, music and cutscenes as faithfully as possible.
The original game comes first. Once everything works as it should, OpenPrivateer can build on that with optional improvements, modern features and modding support. Players who prefer the classic experience can keep it that way.
OpenPrivateer is a playable reconstruction of Privateer and its Righteous Fire add-on, running on the original game data. It is in public alpha.
Most of the original file formats are documented and cross-checked against the real game files, the original executable's own disassembly, and independent third-party tools.
A new game starts from the original's own starting data, and the bases work as they do in the original: the Ship Dealer with equipment, repairs and new hulls, the Commodity Exchange, the Software Booth, the bar, the Research Computers, the guild offices and both mission boards. Generated missions use the original's own encounters and objectives, run their mission scripts in flight, and pay on landing. The Privateer story campaign can be played from Sandoval's first offer to Admiral Terrell's closing credits, with its conversations, cutscenes and plot missions driven by the game's own scripts. Righteous Fire runs on the same engine and can import a Privateer pilot the way the original does.
Saves are compatible with the original game. The Mission Computer loads original
.SAV/.PRS files and writes new ones that the original game
loads, always under a new file name. State the original format cannot hold, such as
parked ships, goes into a separate .openpriv.json file next to the save.
The cockpits, flight model, NPC combat AI, weapons, shields and armour, equipment damage, the tractor beam, cargo drops, ejected pilots, asteroid fields and in-flight communications are reconstructed from the original executable and its data. Keyboard, mouse, joystick and gamepad controls can be remapped, and controller axes and throttles can be calibrated.
Classic aims to reproduce the original gameplay. Enhanced and Modern currently behave the same: they add small conveniences and allow optional OpenPrivateer additions which Classic never enables.
Outside the experience modes, a content-override layer lets players replace game assets or translate the engine's own text. The launcher finds the original game files and configures the game, experience mode, music and settings folder. Release builds check once a day for a newer build and only show a notice; nothing is downloaded automatically.
Multiplayer is an OpenPrivateer addition, since the 1993 game has no networking. A
separate headless openprivateer_server holds one authoritative universe,
and clients join it by direct IP. Players can fly together across several star systems,
fight NPCs and each other, use autopilot and hyperspace jumps, and land to refuel and
relaunch. Trading, missions, persistence and chat are not networked, and bases stay
private local screens.
GAME FEATURES

All bases/planets interiors, animated tiles and sprites, story NPC gating and per-base music.
Load original DOS savegames, working MISSIONS/FIN/MAN tabs and mission rejection in Enhanced/Modern modes.
Commodity Exchange with real buy/sell trading and live per-visit price and stock rolls.
Real buying, selling and repairs, hardpoint selection and savegame-driven display.
Merchant Guild, Mercenary Guild and Mission Machine offers driven by the original mission generator.
All cockpits (supporting sprite-less cockpits), self-destruct, navigation map, mission objectives and original takeoff, landing and jump cutscenes.
Three MIDI backends (OPL2, SF2, MIDI-Mapper) plus CD audio, with real scene and combat music selection.
Render scaling, texture filtering, xBRZ and DOSBox Staging derived CRT Filter and Color Grading.
Generic content overrides plus a full text translation system with auto-generated English catalog and in-game language switching.
Automated Windows, Linux and macOS builds on every push with rolling development artifacts. Other platforms on demand.
Added support for the entire Wing Commander Universe sectors while keeping the original 320x200 Privateer map presentation.
The basic client/server architecture is functional and PVP/PVE multiplayer games are already possible. Mission progression will be added in the future.
Enhanced and Modern modes allow you to own multiple ships. You can switch to other ships while landed on a base.
Enhanced and Modern modes allow you to hire wingmen in case you own multiple ships. There are different skill tiers available each with a different cost per mission.
Full HOTAS support for an authentic hands-on flight experience.
The game will check during startup if a new version is available.

DEVELOPMENT
OpenPrivateer includes optional xBRZ pixel scaling, CRT filter and texture filtering to help the original 320x200 artwork look its best on modern high-resolution displays, while still letting you keep the original pixel-perfect look if you prefer.
HD and widescreen support will come later and gradually evolve alongside the main development, while the original 320x200 experience remains the priority for now.

FAQ
Not quite. It's a new engine built to recreate the original Privateer as closely as possible, using the original game data.
No. You'll need your own copy of Wing Commander: Privateer. OpenPrivateer doesn't include any of the original copyrighted game files.
Yes! The public alpha is available in the Downloads section. Keep in mind that it's still under development, so expect a few bugs.
Yes, that's planned. For now, I'm focusing on getting the original 320x200 game right before moving on to higher resolutions and widescreen support.
VR is high on my wishlist, but there's quite a bit of work to do first, especially getting the 3D models ready.
Yes! You can already replace game assets, add translations, and modify various parts of the game using the original PAK and IFF formats. Support for things like custom ships, bases, and star systems is being expanded.
You can fly around with other players, fight NPCs or each other, jump between systems, and land at bases. Missions and shared campaign progress aren't supported yet.
DONATION
OpenPrivateer is free and will stay free. If you would like to support its development, you can buy me a coffee.
PROJECT CREDITS
Origin Systems, for creating Wing Commander: Privateer.
Space Cadet Rewind's nearly 3-hour Privateer retrospective is one of the most thorough critical playthroughs of the original game available anywhere, and directly informed OpenPrivateer's Enhanced/Modern feature backlog. Thanks for the fantastic video.
Mario "HCl" Brito, together with Maciek "Matrix" Miąsik on wc1g.txt, wrote decades-old hand-reverse-engineered format notes that kicked off this project's .TRE/.PAK and .SHP format work, and cross-checked the PROG mission-bytecode work. Thanks to Mario for sharing his work, knowledge, and experience with the project.
DOSBox and DOSBox Staging have been invaluable tools for running and studying the original Privateer. Their debugger provided the foundation for much of the project's dynamic analysis, and a modified build with targeted runtime logging has made it possible to observe original game state across thousands of executions and validate OpenPrivateer's reconstructed behavior against the real game. Many thanks to both teams for their work. OpenPrivateer wouldn't have come this far without it.
Charles Cafrelli, one of the original Privateer development team, generously shared his own recollections of how the game's gameflow (base/menu) side and its space-combat engine hand state back and forth - insight that helped make sense of mechanisms this project could otherwise only partially piece together from the executable and file formats alone. Thanks to Charles for taking the time to talk to a fan project three decades on.
Edwin Herrell, another member of the original Privateer development team, generously shared firsthand insight into the game's flight model, including its damping behavior, simulated weapon-fire projectiles and lead calculation, and target collision checks. His explanations helped us better understand the original code, clear up some unanswered questions, and confirm parts of our reverse engineering. Thanks to Edwin for sharing his knowledge and helping us better understand the original game.
Our testers, for all the time and patience they've put into OpenPrivateer. From reporting bugs and sharing feedback to doing their best to break the game, they've helped us more than they probably realize. A huge thank you to all of them.
Anthropic Claude, for its help with reverse engineering the original Privateer executable, analyzing assembly code, writing technical documentation, and developing and running tests. With Claude's help, we've managed to accomplish in just a few months what would likely have taken us five years or more otherwise. It's hard to overstate how much of a difference that has made to the project.
