Skate 3 Bevy preservation project

An independent, source-only Rust/Bevy reconstruction of Skate 3's skating, animation, and world systems. The goal is evidence-backed behavioral parity, not a generic skateboarding prototype.

This is an early work in progress. Current systems include riding, pushing, carving, Flickit anticipation and tricks, landing quality and friction, powerslides, manuals, fakie stance, grabs, off-board locomotion, transition physics, grinding foundations, and an extracted University world pipeline.

Important legal boundary

This repository contains no Skate 3 ISO, executable, title update, retail animation bank, character model, texture, or extracted University data. It is not affiliated with or endorsed by Electronic Arts.

You must dump your own legally owned Xbox 360 copy and generate the ignored local assets. Do not upload or redistribute those generated files. See Setup from legally owned game data.

Quick start

Install the prerequisites in the owned-game setup guide, then clone the repository and drag your legally dumped Skate 3 Xbox 360 ISO onto SETUP FROM OWNED ISO.bat. You can also run it directly:

git clone https://github.com/chasmlol/skate3clone.git
cd skate3clone
.\SETUP FROM OWNED ISO.bat "D:\OwnedBackups\Skate 3.iso"

That one command downloads a pinned, hash-verified open-source ISO extractor, extracts the required files from your ISO, builds the retail skater and animation bank, converts University with its textures, collision, and grind data, runs the tests, compiles the game, and launches it. It does not require Skate3Research, SK8, RPCS3, or a separately cloned animation toolkit.

The first asset build is intentionally substantial because Blender generates the complete local animation bank. Later launches and Cargo builds are incremental:

.\LAUNCH LATEST MAIN.bat

For a no-window verification:

.\LAUNCH LATEST MAIN.bat --headless

Those are the only two root launchers in the public distribution: SETUP FROM OWNED ISO.bat performs first-time setup, and LAUNCH LATEST MAIN.bat handles every later run. Old per-feature test launchers and local reverse-engineering wrappers are intentionally excluded.

Controls

• Xbox left stick or A / D: move, steer, and carve
• Xbox A or Space: regular push
• Xbox X or left Shift: mongo push
• Xbox right stick or arrow keys: Flickit input, trick windup, and manuals
• Xbox LT / Q: left-hand grab
• Xbox RT / E: right-hand grab
• Both triggers: two-hand grab
• Xbox B or Circle: footbrake
• Y or Triangle: mount or dismount
• R: reset

Development principles

• Retail behavior is recovered from synchronized telemetry, decoded RX2/ABIN animation data, state/action XML, native-code analysis, and deterministic replay fixtures.
• Proven behavior, bounded inference, unresolved behavior, and human visual verification are kept distinct.
• Retail-derived outputs stay under ignored private directories.
• The simulation runs at 120 Hz and keeps gameplay translation separate from authored animation roots.

The source distribution includes the required permitted conversion code. Provenance and upstream licenses are recorded in THIRD_PARTY_NOTICES.md. The companion Skate 3 trick toolkit remains useful for independent research, but it is not a setup dependency.
