funman300 cd5983ecdd fifa17: cardtype 9 is unnameable -- measured, and the gap closes as a negative
Serving owned balls (subtype 30), league logos (31) and fcc_misccards
(231/232/233/236) was the last projection gap. The open guess was that their
caption would come from `localizedName` on the wire, "probably", and they were
withheld out of caution.

Measured against the running client instead (new
tools/cardtype_dispatch_probe.py, read-only, reproducible, every step with a
positive control). They cannot be named at all:

  1. The merge jump table at rva 0x141eb4 is indexed cardtype-1 with 10 entries.
     Cardtypes 1..5 and 10 each get a DB-merge arm; cardtypes 6,7,8,9 ALL land on
     one shared tail at 0x180141e8a that runs no query and writes no name.
  2. `cmp [reg+0x4c], 9` (cardtype): ZERO sites in .text. For contrast, cardtype
     1 has 13 and cardtype 7 has 6.
  3. `cmp [reg+0x50], 30` and `..., 31` (cardsubtypeid -- the field that actually
     selects a club-item caption): ZERO sites each, while kit 9, stadium 10 and
     badge 11 all appear, which is the control. The only cardtype-9 subtypes
     present anywhere are the four misccards ids, and all four are one boolean
     predicate near 0x1801a72da that returns FALSE for them: an exclusion, not a
     resolver. That predicate is NOT identified and is not claimed to be.
  4. The cardtype-7 resolver is gated `cmp [rax+0x4c], 7` at 0x1800f6f04, so a
     cardtype-9 item never reaches it. Its jne path formats AWARD_LABEL_%i --
     the trophy path, not a fallback that would name a ball.

Nothing reads a localizedName for these subtypes, so sending one cannot become a
caption. Withholding them is a measured limit of the client, not caution, and no
server change can lift it.

CORRECTION: FUN_180119bd0 was recorded as "zero refs in CardsDLL -> almost
certainly an export, its caller is in FIFA17.exe". It is not an export. Its
address occurs exactly once in the whole process, at 0x18021c738 in CardsDLL's
own .rdata, and nothing in FIFA17.exe references it. It is virtual: vtable base
0x18021c2a0, slot +0x498, index 147 -- independently reproducing the recorded
"manager vtable slot +0x498" by a different method. Finding the boundary needs
the constructor-LEA trick; walking back over .text-pointing qwords runs 826 slots
through several adjacent vtables.

Bonus: the shared tail cardtypes 6-9 fall into IS the discard level ladder
(movzx [rdi+0xb4]; cmp 0x4b; cmp 0x41; store [rdi+0x54]), confirming
discard::discard_level instruction for instruction against the live client.

Adapter 244 tests, fmt clean.

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 23 bridge lineage and is kept for historical context.

Run the server (canonical): cd fifa17-recon/docker/fifa17-python && docker compose up -d — see fifa17-recon/FUT-RUNBOOK.md. openfut-core is the shared offline backend (still used by the FIFA 17 path); openfut-bridge is 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.

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.

Disclaimer

This project is not affiliated with EA Sports. You must own FIFA 23 legitimately to use this software. This project does not bypass any ownership verification and is intended only to restore offline playability of a game whose online services have been retired.
