Saw II: Flesh & Blood — Xbox 360 ReXGlue Recompilation

Experimental native recompilation bring-up for the Xbox 360 version of Saw II: Flesh & Blood, built around ReXGlue 0.10.

The repository contains the project scaffold, title-specific function boundary hints, build/runtime tooling and host-side integration code. It does not contain the game executable or retail assets.

Project status: early bring-up. This is not a finished or fully playable PC port.

ReXGlue baseline	0.10.0-dev.g398e2ba

Requirements

The Linux workflow expects a recent 64-bit Linux environment with:

• CMake 3.25 or newer
• Ninja
• Clang 18 or newer
• Git
• Python 3
• Vulkan and the host window/input runtime libraries required by ReXGlue

build.sh detects Arch Linux, Debian/Ubuntu and Fedora-family systems. Missing packages are never installed without explicit authorization.

Game setup

Copy your own supported game extraction into game/. At minimum, codegen needs:

game/Default.xex

The exact supported XEX hash is verified before codegen or runtime startup. See game/README.md for the expected layout.

Build

From the repository root:

./build.sh --bootstrap-sdk

This bootstraps the pinned ReXGlue SDK under .deps/, performs stamp-aware codegen and builds a staged executable. If ReXGlue is already installed:

./build.sh --sdk-prefix /path/to/rexglue/prefix

Useful variants:

./build.sh --debug
./build.sh --release
./build.sh --clean
./build.sh --check
./build.sh --jobs 8

The default configuration is RelWithDebInfo.

Run

With the complete extracted game tree under game/:

./run.sh

Useful diagnostics:

./run.sh --debug
./run.sh --gdb
./test-boot.sh --timeout 30 -- --debug
./gdb.sh

Generated logs, captures, build output, generated PPC translation units and retail game files are ignored by Git.

Development rules

Title-specific function boundaries must be derived from the exact supported XEX. Do not hide unknown guest targets behind broad guessed ranges or generic success stubs. Keep generated recompilation output out of version control and make host-side fixes reproducible whenever possible.
