sk83 Recomp Project

Experimental ReXGlue recompilation project for Skate 3.

This repository intentionally does not include any game files, extracted assets, generated recompilation output, or binaries. Users must provide their own legally obtained copy of the game and generate/build locally.

What Is In This Repo

• ReXGlue project files
• Build configuration
• Handwritten host entry code
• Recompilation configuration metadata

What Is Not In This Repo

• default.xex
• Extracted data/ assets
• Movies, audio, .big archives, or other game content
• Generated C++ output under generated/
• Built executables
• Crash dumps or logs

Local Asset Layout

After extracting your own copy of the game, place files like this:

assets/
  default.xex
  data/
    audio/
    big/
    content/
    fe/
    movies/
    webkit/

The executable expects assets at the project root.

The current config is known against this default.xex SHA256:

4E49F302896A9BEC3B82CD19D5561247F1A50D6040E1A000F02299CE5B7CB7E9

On Windows, check with:

Get-FileHash .\assets\default.xex -Algorithm SHA256

Requirements

• Windows x64
• CMake 3.25+
• Ninja
• LLVM/Clang
• ReXGlue SDK checkout from the sk83-support branch of this fork: https://github.com/chasmlol/rexglue-sdk
• A legally obtained Skate 3 Xbox 360 game dump/ISO
• An Xbox 360 ISO extractor, such as extract-xiso

Build

Clone this repo and the patched ReXGlue SDK branch:

git clone https://github.com/chasmlol/rexglue-sdk C:/rexglue-sdk
cd C:/rexglue-sdk
git checkout sk83-support

Then configure this project with REXSDK_DIR pointing at that SDK checkout:

cd C:/path/to/sk83-recomp
cmake --preset win-amd64-debug -DREXSDK_DIR=C:/rexglue-sdk

Place your extracted game files in assets/, then generate the recompilation output:

cmake --build --preset win-amd64-debug --target sk83_codegen

Build the executable:

cmake --build --preset win-amd64-debug

Run:

.\out\build\win-amd64-debug\sk83.exe

Troubleshooting

If codegen reports hundreds of function errors, make sure you are using the sk83-support ReXGlue SDK branch above, then delete local generated/ and out/ folders and run the configure/codegen/build steps again.

Also verify:

git -C C:/rexglue-sdk branch --show-current
git -C C:/rexglue-sdk rev-parse --short HEAD
Get-FileHash .\assets\default.xex -Algorithm SHA256

The SDK branch should be sk83-support. The default.xex hash must match the hash listed above.

Current Status

This is not a finished PC port. It currently reaches in-game execution on the local test setup, but crashes are still being fixed as more indirect-call/function-boundary cases are discovered.

Legal

Do not upload or redistribute game files, generated code derived from game binaries, or built packages containing copyrighted game content. This project is intended for local research and development using files from a copy of the game you own.
