tl;dr: Command & Conquer: Generals Zero Hour has been natively ported to Apple Silicon Macs, iPhone, and iPad, running the original 2003 engine compiled for ARM64 with DirectX 8 translated through DXVK→Vulkan→MoltenVK→Metal. The port builds on EA's GPL v3 source release and the GeneralsX project, adding iOS/iPadOS support plus RTS-optimized touch controls; users must supply their own game assets via Steam. The engineering was done as a human+AI collaboration using Anthropic's Claude (Fable model), with known issues around iOS memory pressure on long iPad sessions.
