Windows games for x86 and x86-64 PCs, on SwARc’s x86 core and Win32 module (both on by default). The x86 core’s lifter translates their code to C++, and the Win32 platform module reads their PE images and reimplements the Windows, DirectX and middleware APIs they import: Win32 on POSIX and SDL3, Miles, Bink, DirectDraw/Direct3D 7, OpenGL 1.x, Direct3D 9 and D3DX 9, DirectSound, DirectInput and XInput, with Direct3D 11 and XAudio2 on the way for x64 games. Graphics run on SDL_GPU: Vulkan on Linux, native Metal on macOS.

The module is on SwARc’s main branch, in platforms/win32; its commits are the progress log.

It also carries the first native code shared between ports: the Visual C++ 6 runtime that games link statically (string and memory functions, 64-bit helpers, number parsing and formatting, the sprintf and sscanf engines, math intrinsics), reimplemented to match VC6 bit for bit. A port binds its EXE’s copies to it, and an oracle test checks each function against the lifted original. On the graphics device, every fixed-function draw carries its whole state, so a port’s native renderer can draw on the device directly, as CoD1’s back end does.

32-bit games run in a 4 GiB guest address space with the stdcall/cdecl HLE ABI; x64 games use the Win64 ABI, the UCRT and MSVCP140, and AVX.

The x86 core and Win32 are separate layers: the core knows no Windows, so the PS4 module builds on it without any Win32 code.
