Two experiments, both negative, and the negative has a mechanism behind it rather than
being another failed guess.
FUT_CLUB_PAGE served 114 items to /club?...count=11 tile still 0 TOTAL PLAYERS
FUT_CLUBSTATS full stat set, players=114, all modes panel still Players 0
The bodies went out: four "CLUBSTATS: 11 stat rows (players=114)" responses in the log,
panel re-entered afterwards.
FUN_18012fbe0 store+0x78 = request+0xc4 the mode tag is copied from the
REQUEST that just completed
FUN_180043b90 switch (store+0x78)
case 1 +0x800(1)->PLAYERS_EMPLOYED, (0x1e)->BALLS_EARNED, (0x28)->KITS_AVAILABLE,
(0x14)->STADIA_OWNED, (10)->STAFF_EMPLOYED, (0x32)->TROPHIES_WON
case 6 CARDS_NO_TRAINING_*, CARDS_NO_CONTRACT_*, CARDS_NO_FITNESS_*
The MY CLUB summary is case 1, which needs mode 1 (club). The client requests staff,
year and consumables and NEVER club, so the tag settles at 6 and case 1 is never
selected. Our values are stored correctly (contextId 1 forces contextValue 0, the
global bucket the +0x800 getter reads) and case 1 reads exactly the six ids we set.
Nothing ever asks for them.
THE MODE IS CHOSEN CLIENT-SIDE FROM THE REQUEST URL. No response body can change it,
so there is no body that fixes this and generating more of them is wasted work.
Two independent corroborations rather than one story that merely fits:
- case 6 reads 0x3d CONTRACTS, 0x3e TRAINING, 0x40 FITNESS, exactly the three ids
FUN_18012fd40 cannot produce from any type string. The consumables view is
unsettable from this endpoint by construction.
- FUT_CLUB_PAGE eliminated the only other candidate: the tile is not a count of the
list we return.
Both flags stay implemented and default OFF. FUT_CLUBSTATS is correct against the
verified schema and would populate the moment a club-mode request occurred; deleting it
would throw away the schema work for no gain.
Recorded against myself: I argued from the matching labels (tile "TOTAL PLAYERS", panel
"Players", both zero while we served {}) that the two read the same store and one body
would fix both. The store IS shared. The SELECTION is not, and that is what decides it.

OpenFUT
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.
Repositories

Game-independent offline FUT backend |

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.
