Ben 10 Omniverse — native macOS port by static recompilation

Ben 10 Omniverse (PS3, BLUS31017, version 01.00) running natively on Apple Silicon: no emulator, no JIT. The PowerPC (PPU) and Cell SPU code is translated ahead of time into C/C++, compiled with clang for arm64 and linked against a reimplementation of the PS3 OS and libraries. Graphics use Metal, cutscenes VideoToolbox, sound CoreAudio.

This repository contains no game code and no game assets. You need your own legitimate copy of the game; the files below only describe how the build is made and how it is measured.

Sister project: gow2-recomp (God of War II HD), same engine.

Status

Area	State
Boot, logos, intro videos (H.264)	✅ videos decoded by VideoToolbox
Title screen, front-end hub, New Game	✅
First level (Training Simulation 1): walking, dialogue, HUD	✅ plays; later levels not verified
Frame rate	🟡 the game is locked at 30 fps by its own limiter and has a 60 Hz mode of its own; on a fanless MacBook Air M5 the machine reaches 27–59 fps depending on heat and load
Audio	✅ music, voices and effects; short dropouts only on some loading screens
Controllers	✅ GameController (DualShock 4 / DualSense / Xbox / MFi) and keyboard

Measured, not claimed: the per-job cost of the lifted SPU code follows the SoC clock, not the runtime; the notes in notes/ and the harness in bench/ show how the numbers were taken.

What is here

Path	Purpose
recomp.toml, functions.json, spu_jobs.toml	lifter configuration: function bounds, mid-asm hooks, SPU jobs/tasks to lift
host/	host-side code linked into the binary (frame-step hooks, frame pacing policy) with unit tests
bench/	measurement harness: scripted pad input, event-window analysis, A/B scripts
notes/	engineering log: what was measured, what was refuted
build_macos.sh, run_ben10.sh	build and run recipes (environment variables are documented in the script header)
boot_macos.cpp	macOS entry point (guest on its own thread, window pumped on the main thread)

Building

The port is built by build_macos.sh against the engine's runtime library. The engine is a fork of sp00nznet/ps3recomp with a macOS/Metal port and additional work on the SPU runtime; that fork is not public yet, so a clean build from this repository alone is not possible today. Pieces that apply to the upstream engine are being sent there as pull requests (#206, #207, #208).

Notes

• Everything that is an experiment is gated by an environment variable and off by default.
• Findings are written down with the evidence that supports them; refuted hypotheses are kept in the notes.
