# Skate 3 Rust Engine: a Bevy rewrite built on Skate 3 reverse-engineering research > Reimplements Skate 3’s skating, tricks, grinds and offboard movement in a new Rust and Bevy engine that runs on assets converted from the user’s own Xbox 360 copy, adding difficulty settings and a .skate custom-map format. Physics notes cite functions and constants read from the original executable in IDA, and audio research reads traces from a research-hooks branch of a separate Skate 3 static recompilation. README says gameplay parity is still a work in progress, credits dumbad’s years of format research and states that AI coding tools were used to write the rewrite. - Type: Case study - Targets: Game - Category: Independent reconstruction cases - Relationship: Independent reconstruction project - Sources reviewed: 2026-10-19 - Added to the catalog: 2026-11-02 - Original resource: - Primary source: - Catalog page: - Record JSON: - Chinese version: [简体中文](https://awesomerea.org/zh/resources/skate-3-rust-engine-case/index.md) ## Requirements & limits - **Prerequisites:** Play needs the user’s Skate 3 Xbox 360 ISO, or an extracted default.xex with its data folder; setup converts the skater, animations, disc maps and HUD assets into a local data folder, and ISO extraction needs internet access. Skate 3 assets are not included; the bundled format-demo map is described as original procedural content. - **Prerequisites:** Runs on Windows: the release ZIP starts skate3rust.exe and needs an SDL3-compatible gamepad. Source builds need Rust with the MSVC toolchain and LLVM, using BUILD.bat and PLAY.bat; the portable package script needs Python 3.13. - **Limits:** tools/recomp-trace reads traces from the research-hooks branch of Hailey-Ross/skate3recomp, which users must build from their own copy of the game; its README warns that the recompilation’s timing and threading differ from the console game. - **Testing evidence:** The Windows release workflow runs Python tests for the updater, setup and asset pipeline, but not the Rust crates’ own tests. tools/regression-checks compares maps, spawns and customiser output with a user-recorded baseline. Parity results are project-reported. - **License:** Original code is GPL-3.0-only, copyright dumbad and contributors; the vendored, patched Bevy crates and tools under tools/vendor/ keep their own licenses, and no rights are granted to Electronic Arts’ code, data, assets or trademarks or to third-party maps and mods. Unofficial and unaffiliated with EA. - **Attribution:** tools/claude-skills holds Claude Code skills for developing the engine. ## Primary sources 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. ## More in Games - [Snowball War: a bounded REA-assisted minigame reconstruction](https://awesomerea.org/resources/snowball-war-rea-case/index.md) · Case study - [Thyme: Command & Conquer Generals: Zero Hour reimplementation](https://awesomerea.org/resources/thyme/index.md) · Case study - [touhou-engine: a Python reimplementation of Touhou gameplay](https://awesomerea.org/resources/touhou-engine-case/index.md) · Case study - [Untangle: a browser rebuild from REA and Ghidra evidence](https://awesomerea.org/resources/untangle-rea-evidence-rebuild-case/index.md) · Case study - [xoreos: an open reimplementation of BioWare’s Aurora engine family](https://awesomerea.org/resources/xoreos-aurora-engine-case/index.md) · Case study - [z2rs: an incremental Rust reconstruction of Zelda II checked against an emulator](https://awesomerea.org/resources/z2rs-zelda2-reconstruction-case/index.md) · Case study ## About this entry The description was reviewed against primary sources.
