Red Alert 2 and Yuri's Revenge — Static Recompilation

⬇ Download the installer: Windows, Linux and macOS. You need your own copy of the game.

Static recompilation of Command & Conquer: Red Alert 2 (Westwood Studios, 2000) and its expansion Yuri's Revenge (2001) from their shipping Win32 binaries, game.exe 1.006 and gamemd.exe 1.001, to native C. Both games build from the same install, each into its own ra2.exe, with the same remaster: the one the first two C&C games got and this engine never did, built on the game's own code rather than a reimplementation.

Built on the pcrecomp toolchain. Tiberian Sun and Firestorm, the same engine's first games, are recompiled the same way in tiberiansun-recomp. This is not OpenRA, a separate engine that reimplements the rules: this runs Westwood's own code, recompiled.

• Its own window: a Direct3D 11 presenter, resizable or borderless fullscreen (F11, Alt+Enter), sharp at any size and on high-DPI screens.
• Scaling (F12): sharp-bilinear by default, smooth, CRT, nearest, or whole multiples only.
• A settings menu (F10, or right-click beside the picture): scaling, fullscreen, HD vehicles, the bars beside the 4:3 menus, the game's resolution and mods, without editing an INI.
• High resolution and widescreen: 1280x720 up to 3840x2160, more of the battlefield on screen (hires.md).
• HD vehicles: units, their shadows and aircraft drawn at twice the resolution from the game's own voxel models, at no cost in frame time (voxels.md).
• Modern controls (F10): left-click to select, right-click to order, and Shift-click a build icon to queue five (modern-controls.md).
• Mods: a folder in mods/, laid over the game's without changing it, switched in game (mods/README.md).
• LAN multiplayer, RA2 against RA2, as shipped (IPXEmu).
• Windows, Linux and macOS, natively on all three: no Wine, and no Visual C++ redistributable to install. It also runs under Wine and CrossOver.

--classic gives the original display, and --original runs the shipping machine code for comparison.

You need your own copy: the Steam or EA App (Origin) build of Command & Conquer: Red Alert 2 and Yuri's Revenge, the folder holding game.exe and gamemd.exe. Nothing from the game is in this repository or downloaded for you; everything is built on your machine from your copy.

1. Download the one for your system from the latest release: RA2-Recomp-Installer-windows-x64.exe, -linux-x64.tar.gz or -macos-arm64.zip.
2. Open it. It finds your game in Steam or the EA App, or you point it at the folder.
3. Press Build my recomp, and when it's done, Play.

The first build takes 30 to 60 minutes and about 6 GB; it installs the tools it needs (on Windows, Visual Studio's Build Tools, asking for permission once). The installers aren't signed yet: on Windows, SmartScreen asks first (More info, then Run anyway); on a Mac, right-click it and pick Open.

1. Download this repository (the green Code button, then Download ZIP) and unzip it somewhere with 6 GB free.
2. Windows: double-click Setup.cmd. Linux and macOS: ./setup.sh.
3. Play with Yuri's Revenge (recomp) or Red Alert 2 (recomp) in that folder.

The script asks before installing anything, finds the game, and catalogs, lifts and builds both games; a rerun skips finished steps. Building by hand, each platform's details, Wine and the command line are in docs/building.md.

In the game: F10 settings, F11 fullscreen, F12 scaling, F9 mods at the main menu (Linux and macOS). On a Mac hold fn for the F keys, and use Option+Return for fullscreen.

v0.1.0-alpha.1, playable. Both games lift with 0 errors and play: the intro, every menu, skirmishes from setup to the score screen, and both campaigns, 720p to 4K. A scripted playtest suite checks it: 30 of 30 for each game on Windows, natively on Linux and macOS.

bringup.md is the log of each wall and its fix, and ROADMAP.md what comes next.

Recorded headlessly by the recompiled game. HD vehicles, 1x on the left and 2x on the right:

• docs/building.md: building by hand, Linux, macOS, Wine, the command line, the lifted C
• docs/RECON.md: the binaries, the build and the class map
• docs/host.md: the host, headless DirectDraw, registration-free COM
• docs/presenter.md: the presenter window, scaling, the virtual screen
• docs/hires.md: high resolution and widescreen, and the 4K sidebar fix
• docs/voxels.md: the voxel renderer, mapped, and HD voxels
• docs/bringup.md: every wall so far and its fix
• docs/testing.md: the playtest suite, scripted input, the --original oracle and the LAN game
• ROADMAP.md, CHANGELOG.md, CONTRIBUTING.md
