FIFA 17 makes a club item resident ONLY through squad.actives. The squad
parser's arm for atom 11 computes the address of the i-th element of the
client's five-element club-item array and hands it to the item
deserializer as the out-handle:
cmp edi,0x5 ; at most five entries are read
mov rax,QWORD PTR [r13+0x108] ; the club-item array
lea rcx,[rax+rcx*8] ; &array[edi]
call 0x18013fe00 ; item deserializer, writing that slot
That deserializer inserts the record into the client's resident item map
- keyed by wire instance id, gated only on the id being non-zero - and
binds the slot handle to it. So each element must be a full item object
like squad.manager[].itemData; an id reference alone installs nothing,
because the manager installer looks its id up in that same map and does
nothing on a miss.
We emitted actives: [] as an 'observed constant', which was circular: it
came from our own captures and the Python oracle seeded it. The client
then read the array-end token immediately, parsed nothing, and left all
five slots null, so every lookup resolved to the static not-found
sentinel whose item pointer is NULL. That is why the pre-match kit
selector had no kits, and it is also why /club?type=kit could never fix
it: no /club response feeds that array.
Core already owns the designations via /club/active-items, so the host
reuses get_active_kits() and the adapter shapes each entry with the same
shape_club_item primitive /club?type=kit uses, keeping one wire dialect.
A Core transport error yields no actives and is reported rather than
silently empty. userInfo.actives already mirrors the squad's.
Verified against the client's own fcc_kitcards table: 6300006 is team
21's home card (category 2) and 6400003 the away card (category 3).
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 Everything below this banner describes the superseded FIFA 23bridgelineage and is kept for historical context.Run the server (canonical):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.
