SwARc
The Swiss Army Recompiler: static recompilation of PC and console games into native 64-bit programs for Linux and macOS: the scaffold that gets a game running natively while its code is replaced, piece by piece, with hand-written C++.
- 7 ports
- 4 systems
- 1 playable
- 4 in game
A game’s machine code is translated ahead of time into C++ and linked against a runtime that reimplements the parts of its operating system and middleware the game uses. There is no emulator, interpreter or Wine in the result, and no game code or data in any of the repositories: each port builds from your own copy of the game.

What SwARc provides
Three layers, each building only on those below it: a base every guest shares, a CPU core per guest CPU, and platform modules (an operating system and its libraries) on a core. A game builds its own core and platform and nothing else: a PS4 game pulls in no Windows code, a Switch game no x86 code. All of it is on SwARc’s main branch, each core and module behind its own build option.
- Base: SDL3 windows, input and audio output, ffmpeg, a graphics device on Vulkan and native Metal, a software mixer with EAX 1-3 reverb, the guest address space, frame pacing, and Berkeley SoftFloat under every core’s floating point.
- CPU cores: a lifter that emits C++ for every function of a game’s
executables with exact semantics, the CPU model that code runs on, and
tests against an oracle.
- x86 and x86-64: integer, exact 80-bit x87, SSE to SSE4.2 and AVX, checked against the host CPU.
- PowerPC: 64-bit PowerPC in 32-bit mode, exact floating point, VMX and the Xenon’s VMX128, checked against QEMU’s PowerPC 970.
- AArch64: integer, flags and the exclusive monitor so far, checked against Unicorn and, on arm64 hosts, the CPU.
- Platform modules: the system’s executable formats and its system
libraries, reimplemented (HLE).
- Win32 for the PC, on the x86
core (
platforms/win32). - Orbis for the PlayStation 4, on
the x86-64 core (
platforms/orbis). - Xbox 360 for the Xbox 360, on
the PowerPC core (
platforms/xbox360). - Horizon for the Switch, on
the AArch64 core (
platforms/horizon).
- Win32 for the PC, on the x86
core (
The lifted code is an exact oracle, not the end product: each port replaces lifted functions with native C++ one subsystem at a time, checked against the lifted original, until nothing lifted is left.
The repository has the build instructions and ARCHITECTURE.md, the design.
