The route was right and the body was wrong. We served bare items, the client took the
response and inserted NOTHING (the live card map held only the 11 squad players), and
the screen stayed empty with no error logged anywhere. A 200 with a well-formed body
that the consumer silently discards is the worst failure shape there is, and it is the
third time this project has hit it.
FutConsumablesSearchServerResponse resolved from the RS4 literal 0x1802222f8:
factory 0x180130a10, vtable 0x180222200, deserializer +0x08 = 0x180130d10 (6873
chars). It takes itemData(0x16b) at the root like the club list, but its ELEMENT is
not an item. It is a five-atom wrapper and exactly one of the five carries the item:
0xbc count int
0xd7 discardValue int
0x16a item -> FUN_18013fe00, the item parser itself
0x287 resourceId int
0x362 untradeableCount int
Everything else goes to the value-skip handler, which is precisely why a bare item was
accepted and did nothing. It also explains the UI: FUT draws consumables as one stack
with a quantity, not as N cards, and the wrapper is that quantity.
Identical consumables are now collapsed by resourceId and counted.
439 + 414 checks green.

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
| Repo | Purpose |
|---|---|
openfut-core |
Game-independent offline FUT backend |
openfut-bridge |
FIFA 23 integration layer + reverse-engineering proxy |

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.
