Madeira

Madeira is an experimental compatibility project for running x86-64 Windows PC games on a non-jailbroken iPhone. It combines Wine using ARM64EC, FEX-Emu for x86-64 to ARM64 translation, and DXMT for Direct3D 11 to Metal graphics conversion. All major components operate inside a single Mach process, with wineserver adapted to run as a thread. The project requires JIT execution, which on iOS is enabled through debugger attachment rather than ordinary App Store distribution. Games such as Thumper and ULTRAKILL have reached playable states, while other titles vary widely in performance and stability. Building requires custom forks of Wine, FEX, and DXMT together with Xcode tooling. Madeira is explicitly a research project with breaking changes and per-game compatibility issues.
