Dig 2: traced the GetAuthCode send path up to FIFA's game-side nucleusConnectREST (+0x2861910) / nucleusConnectTrusted (+0x5078370). Both null-check the same Nucleus session context [NucleusManager+0x778] and short-circuit when null (REST returns 0/sends nothing; Trusted returns HRESULT 0x80060000 not-ready). So the online->auth gate is that +0x778 is never instantiated -- consistent with the no-op-listener finding (event updates stored state but doesn't drive the login state machine to create the context). Next: a targeted dynamic probe on REST + the +0x778 read. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
OpenFUT Bridge
FIFA 23 integration layer and reverse-engineering proxy.
OpenFUT Bridge sits between the FIFA 23 client and the internet. It intercepts all FUT API traffic, logs every request, and routes known endpoints to OpenFUT Core. Unknown endpoints receive safe placeholder responses so the client keeps running.
What it does
- Transparent HTTP proxy — point FIFA 23 here instead of EA's servers
- Logs every request (method, path, headers, body, timestamp) to
captures/ - Maps known FUT endpoints to OpenFUT Core API calls
- Returns placeholder JSON for unknown endpoints (prevents client crashes)
- Admin API for reviewing captures and identifying unmapped routes
- Foundation for building the full FIFA 23 integration

cargo run
# Or with config

Reverse Engineering Workflow
- Point FIFA 23 at the Bridge (see
docs/setup-notes.mdfor proxy setup) - Start a game session
- Check
captures/or/_bridge/unknownfor new endpoints - Document the endpoint in
docs/endpoint-map.md - Add a mapping in
src/mapper.rs - Implement the Core handler
Proxy Setup (Research Notes)
See docs/setup-notes.md for notes on:
- Windows
hostsfile redirection - RPCS3 network config (PS3)
- Certificate bypass approaches
- mitmproxy integration
