GeneralsXWeb - Command & Conquer: Generals Zero Hour in the browser

⚠️ Experimental. This port is under active development: expect rendering glitches, missing subsystems (audio, multiplayer), broken saves, and breaking changes between commits. Not affiliated with or endorsed by EA.

GeneralsXWeb is a WebAssembly port of GeneralsX, the cross-platform build of Command & Conquer: Generals - Zero Hour. The engine compiles to wasm with Emscripten and renders through Dvijoke d8web, a Direct3D 8 → WebGL2 translation layer. No streaming, no server-side execution - the whole engine runs in your browser tab.

Play it at Igroteka - the site stages your own game files (Steam copy required) into browser storage; nothing is uploaded or hosted.

Proof of concept

gameplay.mp4

cold boot, .big asset load, main menu, skirmish setup, and a base going up under AI pressure - one Safari tab, no streaming, no server.

What works

• Boots to the animated shell map and main menu at 1024×768 (WebGL2)
• Full INI/asset pipeline from the original .big archives
• Skirmish AI scripts, menu UI, text rendering, game options
• Tested in Safari and Chrome; Brave needs its fingerprint shield off

How it is built

• wasm CMake preset, Emscripten toolchain (cmake --preset wasm, then cmake --build build/wasm --target GeneralsXZH.js)
• wasm/ holds the browser glue: boot harness and the d8web bridge shim
• Graphics go through the statically linked d8web backend instead of DirectX
