Command and Conquer Generals natively ported to macOS, iPhone, iPad using Fable

Comments

Zero Hour running natively on Apple Silicon Macs, iPhone, and iPad - campaign, skirmish, and Generals Challenge, with touch controls built for RTS (tap-select, drag-box, long-press deselect, two-finger scroll, pinch zoom). No emulation: this is the real 2003 engine compiled for ARM64, rendering DirectX 8 → DXVK → Vulkan → MoltenVK → Metal.

Built on EA's GPL v3 source release via fbraz3/GeneralsX (which did the heavy lifting of the macOS/Linux port - this fork adds the iOS/iPadOS port and a set of engine fixes). The original GeneralsX README lives on the upstream-main branch.

No game assets are included or distributed. You need your own copy (Steam, ~$5 on sale).

Prerequisites (one time)

# Toolchain
xcode-select --install
brew install cmake ninja meson pkgconf
brew install --cask steamcmd

# vcpkg (full clone - a shallow clone breaks manifest baselines)
git clone https://github.com/microsoft/vcpkg ~/vcpkg && ~/vcpkg/bootstrap-vcpkg.sh
export VCPKG_ROOT=~/vcpkg # add to your shell profile

# LunarG Vulkan SDK (NOT the Homebrew cask) - https://vulkan.lunarg.com/sdk/home
export VULKAN_SDK=$HOME/VulkanSDK/ /macOS # add to your shell profile

Clone, build, get assets, play

git clone https://github.com/ammaarreshi/Generals-Mac-iOS-iPad.git GeneralsX
cd GeneralsX

./scripts/build/macos/build-macos-zh.sh # checks deps, configures, builds
./scripts/build/macos/deploy-macos-zh.sh # creates ~/GeneralsX/GeneralsZH + run.sh
./scripts/get-assets.sh # fetches game data you own

cd ~/GeneralsX/GeneralsZH && ./run.sh -win

iOS/iPadOS build

On top of the macOS prerequisites: full Xcode (signed into your Apple ID), brew install xcodegen, and a (free or paid) Apple Developer team.

cd GeneralsX
git submodule update --init references/fbraz3-dxvk # iOS DXVK is built from this + Patches/dxvk-ios.patch
./scripts/build/ios/fetch-moltenvk.sh # pinned MoltenVK.framework (checksummed)
./scripts/build/ios/stage-fonts.sh # Liberation fonts, renamed as the game expects
cmake --preset ios-vulkan
cmake --build build/ios-vulkan --target z_generals

GX_TEAM_ID= GX_BUNDLE_ID=com.you.generalszh \
  ./scripts/build/ios/package-ios-zh.sh --install # assembles, signs, installs

Find your team id in Xcode → Settings → Accounts. Assets ship inside the app bundle (self-contained install); --dev skips the ~2.7 GB copy for fast code iteration.

Key files and directories

Known issues

• Long sessions on iPad can be killed by iOS for memory (~3 GB+ resident); the app exits to the home screen with no dialog. Session logs (current + previous) are in the Files app under the game's folder. Under investigation.
• Backgrounding mid-game can occasionally crash on iOS - the lifecycle pause covers the common paths; a rare race remains. Save often.

Licensing and credits

Engine code GPL v3 (EA's source release → GeneralsX → this fork). Game assets: not included, not licensed here.

This port was built as a human+AI collaboration: engineering by Claude Code (Anthropic's Claude, Fable model), directed and playtested on real devices by Ammaar Reshi. The engineering log in docs/port/ is the unedited record of how that worked.
