funman300 8f98e6adda tools(fifa17): probe the manager-only chemistry slots to settle inferred vs proven
`card_identity_probe` reads the PLAYER slots (F_NATION 0x148, F_LEAGUE 0x154). A
manager does not use those, so grading a manager with it reports nation=0 /
leagueId=0 and reads like a server bug when it is only the wrong offsets.

The manager layout, from the Ghidra reversal already recorded in fut_staff.py, is
teamid rec+0x94, nation rec+0xde, leagueId rec+0xe0, talkrating rec+0xe2,
negotiation rec+0xe3. The managercards merge (FUN_1801356c0) NEVER writes +0xde
or +0xe0, which is exactly what makes them a clean test: whatever sits there came
from our JSON and nowhere else.

Read against the live client (pid 6580, 27 records in the CardsDb map):

  resource   teamid  nation  league  talkrating  negot   verdict
  1000509    241     45      53      0           3       SERVER FIELDS LANDED

So the manager's chemistry fields DO reach the record, and `negotiation=3` agrees
with managercards row 1000509, i.e. the merge ran as well. That moves manager
nation/league from INFERRED to PROVEN without a screenshot.

Read-only: /proc/PID/mem is opened 'rb' and there is no write path.

OpenFUT

⚠️ Status — see docs/PROJECT_STATE.md (canonical). The working, actively-developed target is FIFA 17, not FIFA 23. Everything below this banner describes the superseded FIFA 23 bridge lineage and is kept for historical context.

Run the server (canonical): cd fifa17-recon/docker/fifa17-python && docker compose up -d — see fifa17-recon/FUT-RUNBOOK.md. openfut-core is the shared offline backend (still used by the FIFA 17 path); openfut-bridge is the retired FIFA 23 integration.

Offline Ultimate Team — like SPT, but for FIFA 23.

OpenFUT replaces EA's retired FUT servers with a fully offline, single-player backend. You own FIFA 23 legitimately. You just want to keep playing after EA shut down the servers.

Core is game-independent. It speaks a clean REST API and knows nothing about FIFA 23 internals.

Bridge is FIFA-specific. It speaks FIFA 23's wire protocol and translates it into Core API calls. Bridge is where all reverse engineering work happens.

Running

# Start the offline backend
cd openfut-core
cargo run

# Start the proxy (for traffic capture / FIFA integration)
cd openfut-bridge
cargo run

Core listens on http://127.0.0.1:8080 by default. Bridge listens on http://127.0.0.1:8443 by default.


Design Principles

  • Offline-first. No EA account required. No internet connection needed.
  • Single-player only. This is not a multiplayer server emulator.
  • Data-driven. All cards, packs, SBCs, and objectives are JSON files. Everything is moddable.
  • Clean architecture. Core has zero knowledge of FIFA 23. Bridge has zero game logic.
  • No copyrighted assets. No real player images, no EA trademarks in data files.

This project is not affiliated with EA Sports. You must own FIFA 23 legitimately to use this software. This project does not bypass any ownership verification and is intended only to restore offline playability of a game whose online services have been retired.
