LIVE 2026-08-04, and this corrects the body I shipped an hour ago. Selecting the ENGLAND tab on the MY CLUB screen issues exactly one request: 14:30:32 GET /ut/game/fifa17/club/stats/country/14 (14 = England) and NO item-list request. So that tab is driven entirely by per-nation stats, and it showed nothing while the club holds 8 England players. THE GUARD WAS THE BUG. In deser 0x180130150, contextId == 1 or 5 <= contextId <= 9 FORCES contextValue to 0, which is the global bucket that the +0x800 getter reads. The per-nation view reads the +0x7f8 getter keyed by the NATION ID instead. Every row I sent carried contextId 1, so no matter what contextValue said, everything landed in the global bucket and the per-context tabs could never see it. I had the guard written down in my own comment and still sent a body that tripped it on every row. Now, for country/<id>, league/<id> and team/<id>, the response carries the global rows AND per-context rows keyed by that id, computed from the club's real nation/leagueId/ teamid fields: country/14 -> players 8, playersGold 8, rarePlayers 8, silver/bronze/kits/badges 0 Both sets ride in the SAME response because every response wipes the whole map first, so anything left out is erased rather than merged. contextId 3 is used purely because it is OUTSIDE the guard and therefore preserves contextValue. TODO/CONFIRM what contextId means semantically; nothing read so far gives it a meaning beyond that guard. Also verified rather than assumed this round: all 11 type strings we emit resolve correctly against docs/fut_atoms.tsv (players 0x238, rarePlayers 0x272, stadia 0x2d7, balls 0x4f, kits 0x17c, badges 0x4b, trophies 0x340 ...), 0 mismatches. So the strings were never the failure. Does NOT claim to fix the MY CLUB hub counter, which remains the open question in S19. This fixes the nation/league tabs, which is a different and now-understood symptom. 392 checks green. Still behind FUT_CLUBSTATS, default off.

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.

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

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.
