ps2recomp

Turns a PS2 game ELF or disc image into a native binary. The
stages are ingest, discover, lift (R5900 to IR), emit (C++), link,
profile and verify. The tool and its repo are called recomp.

Status    As of 2026-09-30, milestones M0 to M2 have passed their
          gates. M3 is in progress: a software GS rasterizer that
          has to match the Play! emulator at SSIM 0.97 or better.
          The comparison tooling is done; the rasterizer is next.
          Only the project's own test programs have been
          recompiled and run (hello, kthread), on Windows 11. No
          game has.

Coverage  98.95 to 100 percent of executed cycles are translated on
          the test programs and ps2sdk samples. The rest is
          syscalls and the interrupt return stub, which stay on
          the embedded interpreter.

Requires  An ELF or disc image you own. No BIOS, and no
          commercial files are bundled or used in testing.

Usage     recomp build game.elf --platform ps2 --target x86_64-windows
