The plan called this "the single blocker between 'we can mark a kit equipped'
and 'we can equip a kit'", and recorded that two attempts to find the writer
drowned at 1688 and 4144 instructions.
They drowned because +0x60 is a common struct offset. Two filters make it
readable: only an IMMEDIATE store can introduce a constant (a register store
just propagates one), and item-record code is recognisable by touching +0x4c
(cardtype) or +0x5c (itemState) within a few instructions.
Measured read-only against pid 6580:
- live +0x60 over all 27 resident records: {1: 23 players, 0: 4 staff}, never 4
- CardsDLL has 4 comparisons of +0x60 (0, 0, 1, 4); the 4 is the kit gate and
is the ONLY such comparison in the process
- CardsDLL has 29 immediate stores to +0x60, constants {-2,0,1,908,0x3f800000}
- FIFA17.exe, across 79 MB of code: ZERO stores of 4, zero comparisons with 4
- the gate function has one xref (a jmp) and its address is never taken
- every register store to +0x60 in CardsDLL is a struct copy or an init
So the gate is not a wire field we failed to send: the value it demands is never
produced by anything. Decoding it fully also shows every OTHER input is already
served — cardtype 7, itemState 101/102, teamid — leaving only the +0xba variant
selector beneath it, which makes a client-side patch the only remaining avenue.

⚠️ 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 Everything below this banner describes the superseded FIFA 23bridgelineage and is kept for historical context.Run the server (canonical):
cd fifa17-recon/docker/fifa17-python && docker compose up -d— seefifa17-recon/FUT-RUNBOOK.md.openfut-coreis the shared offline backend (still used by the FIFA 17 path);openfut-bridgeis 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.

SQLite database
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.
