Operator exported futSelectTeam.BIG (88272 B, BIGF, 11 members). Confirmed the
right screen: FUT_GET_MATCH_KITS_DP, CheckIsKitLocked, mcLockHome and
KITS_AVAILABLE all present. Members split out and committed:
futSelectTeam_Apt1.bin 14526 B magic Apt1
futSelectTeam_AptData.bin 20630 B magic "Apt Data:1:7:8"
STRUCTURE, measured rather than assumed:
* Apt1 is header + a u32 STRING POINTER TABLE + an 8-byte-aligned string table.
Every symbol has exactly one u32 reference and the refs run in the same order
as the strings, so they are pointers, not code references.
* Apt Data holds the actions. Opcode frequencies are AVM1-shaped - GetMember
0x4e x309, If 0x9d x172, CallMethod 0x52 x160, DefineFunction2 0x8e x33,
Jump 0x99 x74 - but two non-standard opcodes dominate (0xaf x1081,
0xb9 x1064), so this is EA's extended dialect and strings are referenced by
table offset instead of a SWF ActionConstantPool.
Adds avm1_disasm.py, which reads the standard subset and prints unknown opcodes
with their length rather than skipping them. It is NOT sufficient for this file:
decoding 0xaf/0xb9 is the remaining work, and OpenSAGE apt-toolkit is the
reference implementation for EA APT actions.
So CheckIsKitLocked is located but not yet READ. What is known stays known: the
native side only ever writes LOCKED = 0, so the predicate lives here.
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 Everything below this banner describes the superseded FIFA 23bridgelineage and is kept for historical context.Run the server (canonical):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.
