# Handoff — LSX handshake complete end-to-end
|
||||
|
||||
**Date:** 2026-07-02
|
||||
**Scope of the session:** `openfut-bridge` (the delivery test) that expanded into
|
||||
`openfut-launcher/openfut-hook` (the fix). Nothing was committed — everything below is
|
||||
uncommitted working-tree state.
|
||||
|
||||
Read `docs/connection-gate-findings.md` (bottom two sections) for the full technical
|
||||
narrative. This file is the short "where we are / what to do next" version.
|
||||
|
||||
---
|
||||
|
||||
## TL;DR
|
||||
|
||||
FIFA 23 now completes the **LSX handshake and holds a sustained encrypted session
|
||||
against our own bridge**, live — the first EA-side step our code services end-to-end.
|
||||
Three changes made it work:
|
||||
|
||||
1. **Hook redirect** — FIFA's `connect(127.0.0.1:3216)` is rewritten to `:3217` by our
|
||||
hook. The existing in-process offline shim keys on **port 3216 specifically**, so a
|
||||
different port slips past it and lands on our host bridge (loopback is shared with
|
||||
the Wine/Proton prefix — same netns).
|
||||
2. **AES key** = `000102030405060708090a0b0c0d0e0f`. The `[0,1,2,…,15]` sequence that
|
||||
looked like a placeholder is the actual session key; confirmed by round-tripping
|
||||
against a captured live session.
|
||||
3. **Session-seed fix** — `compute_seed()` must take the **raw ASCII bytes** of the
|
||||
first two chars of our response hex, not parse them as a hex pair.
|
||||
|
||||
Last live run: FIFA held one `ESTAB` connection to the bridge and drove 20 EbisuSDK
|
||||
requests with **no crash**.
|
||||
|
||||
---
|
||||
|
||||
## Current deployment state (IMPORTANT)
|
||||
|
||||
- **The redirect hook is currently deployed** as `/mnt/games/FIFA 23/version.dll`
|
||||
(md5 `dab3952809c24122af228a3201b9357b`). While this is in place, FIFA routes LSX to
|
||||
our bridge and **requires the bridge running on 3217** or LSX will not complete.
|
||||
- **Backup of the previous hook:**
|
||||
`/mnt/games/FIFA 23/version.dll.pre-lsx-redirect.bak` (md5 `fb7a5aae…`).
|
||||
- **To restore the previous behavior for normal offline play:**
|
||||
```bash
|
||||
cp "/mnt/games/FIFA 23/version.dll.pre-lsx-redirect.bak" "/mnt/games/FIFA 23/version.dll"
|
||||
```
|
||||
- The bridge process from this session may or may not still be running. Check:
|
||||
`pgrep -a openfut-bridge` / `ss -tlnp | grep 3217`.
|
||||
|
||||
---
|
||||
|
||||
## Uncommitted changes (nothing is committed)
|
||||
|
||||
### `openfut-bridge`
|
||||
- `src/lsx.rs`:
|
||||
- **Seed fix** in `compute_seed()` (the load-bearing change).
|
||||
- AES-128 hand-roll replaced with the `aes` crate (+ a FIPS-197 unit test
|
||||
`aes128_matches_fips197_and_round_trips`).
|
||||
- A debug log line dumping raw session ciphertext (used during verification against
|
||||
the capture; harmless to keep, or remove).
|
||||
- `Cargo.toml` / `Cargo.lock`: added `aes = "0.8"`.
|
||||
- `docs/connection-gate-findings.md`: corrected classification + new "LSX complete"
|
||||
section.
|
||||
- `docs/HANDOFF-lsx-2026-07-02.md`: this file.
|
||||
- `captures/lsx-handshake-capture-2026-07-02.log`: a captured live handshake plus the
|
||||
raw session ciphertext, kept as a reference sample for verifying the implementation.
|
||||
|
||||
### `openfut-launcher/openfut-hook`
|
||||
- `src/connect_hook.rs`: added a `PORT_LSX_NBO (3216) → PORT_LSX_TARGET_NBO (3217)` arm
|
||||
in `redirect_if_ea`, plus result logging on the redirect path.
|
||||
|
||||
> There is **other** pre-existing uncommitted work in these trees from before this
|
||||
> session (e.g. bridge TLS/proxy changes, core changes). Do not sweep it into a commit
|
||||
> without checking with the user. Confirm scope before committing anything.
|
||||
|
||||
---
|
||||
|
||||
## How to reproduce the working LSX session
|
||||
|
||||
1. **Build the hook** (redirect):
|
||||
```bash
|
||||
cd openfut-launcher/openfut-hook
|
||||
cargo build --release --target x86_64-pc-windows-gnu
|
||||
```
|
||||
2. **Deploy it** (back up first — already backed up once):
|
||||
```bash
|
||||
SRC=openfut-launcher/openfut-hook/target/x86_64-pc-windows-gnu/release/openfut_hook.dll
|
||||
cp -f "$SRC" "/mnt/games/FIFA 23/version.dll"
|
||||
```
|
||||
3. **Build + run the bridge on 3217:**
|
||||
```bash
|
||||
cd openfut-bridge && cargo build --release
|
||||
LSX_ADDR=127.0.0.1:3217 RUST_LOG=openfut_bridge=debug \
|
||||
./target/release/openfut-bridge > /tmp/bridge-lsx.log 2>&1 &
|
||||
```
|
||||
4. **Launch FIFA** (user does this — umu/Steam via
|
||||
`/home/alex/Desktop/launch-fifa23-live-editor.sh`).
|
||||
5. **Verify:** `ss -tnp | grep 3217` should show `ESTAB FIFA23.exe ↔ openfut-bridge`,
|
||||
and `/tmp/bridge-lsx.log` should show multiple `LSX: dispatch …` lines (not one
|
||||
garbage message).
|
||||

|
||||
|
||||
## Key facts / constants
|
||||
|
||||
| Thing | Value |
|
||||
|---|---|
|
||||
| EA App LSX port (FIFA connects here) | `127.0.0.1:3216` |
|
||||
| Redirect target (our bridge LSX) | `127.0.0.1:3217` (`LSX_ADDR`) |
|
||||
| LSX AES-128-ECB key | `000102030405060708090a0b0c0d0e0f` |
|
||||
| Our greeting key (challenge plaintext) | `cacf897a20b6d612ad0c05e011df52bb` |
|
||||
| Session seed rule | first **two ASCII chars** of our `ChallengeAccepted` response hex, as raw bytes (e.g. `"0f…"` → `0x3066`), NOT the parsed hex pair |
|
||||
| Existing shim interception | in-process, keyed on **port 3216**; loopback is shared (FIFA netns == host netns) |
|
||||
|
||||
Small verification helpers (`keyscan.py`, `seedscan.py`) live in the session
|
||||
scratchpad — trivial to recreate from `connection-gate-findings.md` if needed.
|
||||
|
||||
---
|
||||
|
||||
## Next steps (in priority order)
|
||||
|
||||
1. **Add a `GetGameInfo GameInfoId=…` handler** to the bridge dispatcher (`src/lsx.rs`
|
||||
`dispatch()`). It currently falls back to the generic `<Ok/>` ("unknown request
|
||||
type"). FIFA tolerated that, but may need real responses to progress. This is the
|
||||
immediate iteration surface now that we can see FIFA's real requests.
|
||||
2. **Watch how far FIFA advances** with the LSX session satisfied — the next step is
|
||||
the Blaze/online layer (the old M2 `ONLINE_STATUS_EVENT` blocker). With LSX now
|
||||
handled by our bridge, that picture may change; re-evaluate M2 with FIFA actually
|
||||
reaching it.
|
||||
3. **Port the seed fix into the hook's own `src/lsx.rs`** if the in-process LSX path is
|
||||
ever revived — it has the same `compute_seed` bug.
|
||||
4. **Decide on the redirect's permanence** — right now it's a manual DLL swap. If
|
||||
LSX-via-bridge becomes the intended path, the launcher's setup/deploy flow should
|
||||
own it.
|
||||
|
||||
## Open question for the user
|
||||
|
||||
We never captured what FIFA showed **on screen** during the successful run (advanced to
|
||||
a menu? sat at "connecting"? waited on `GetGameInfo`?). Ask, or observe on the next
|
||||
launch — it tells you whether LSX is fully satisfied or whether `GetGameInfo` is the
|
||||
next thing to address.

# Blaze Handshake — Reference & Milestone Map
|
||||
|
||||
This is the reference for the **blaze_brain** arc: emulating the EA Blaze backend
|
||||
well enough for FIFA 23 FUT to get past *"FUT is connecting to the EA Servers…"*.
|
||||
It replaces the earlier in-process *forcing* arc, which concluded that the game's
|
||||
online dispatch scaffold cannot be filled by forcing local state — it fills only when
|
||||
a real Blaze exchange happens.
|
||||
|
||||
Every claim below is tagged so that on a re-read you can see instantly what is
|
||||
grounded in our own reverse engineering versus what is general public knowledge of
|
||||
Blaze's protocol shape versus what still needs a capture:
|
||||
|
||||
- **CONFIRMED** — established by our own RE in this project (live memory reads,
|
||||
objdump, hook logs).
|
||||
- **SHAPE** — the general shape of EA's Blaze protocol from public community
|
||||
knowledge. The *ordering* and *purpose* are reliable; exact numeric IDs and field
|
||||
tags for FIFA 23's specific Blaze version are **not** implied by a SHAPE tag.
|
||||
- **UNKNOWN** — must be captured from the live client before it can be implemented.
|
||||
|
||||
> Clean-room discipline: nothing here derives from leaked EA source. The Blaze
|
||||
> protocol shape is reconstructed from public community reverse-engineering of EA
|
||||
> titles and our own observations of this client.
|
||||
|
||||
---
|
||||
|
||||
## The three layers that all say "connecting to EA"
|
||||
|
||||
"Connecting to EA" is not one thing. Three distinct systems wear that label, stacked
|
||||
on top of each other, and it is easy to confuse a stall in one for a stall in
|
||||
another. Understanding which layer the FUT spinner belongs to is the whole point of
|
||||
this document.
|
||||
|
||||
**Layer 0 — LSX (Local Socket eXchange).** `CONFIRMED working.` This is the
|
||||
Origin/EA-App desktop-client local API: entitlements, the local login handshake, and
|
||||
`GetAuthCode`. It is *not* Blaze — it is a localhost protocol the game uses to talk to
|
||||
whatever is standing in for the EA App. Our native bridge answers it on ports
|
||||
3216/3217, and answering it is what got the client to the main menu with a working
|
||||
first-party login. Layer 0's output that matters to Blaze is a **Nucleus auth code /
|
||||
access token**: the credential the client will later present to the Blaze
|
||||
authentication component.
|
||||
|
||||
**Layer 1 — the Blaze core session.** *This is the wall.* Blaze is EA's online backend
|
||||
framework. Reaching it is a multi-step handshake (detailed below) that starts by
|
||||
asking a *redirector* where the real server is, connecting there over TLS, then
|
||||
negotiating configuration, authenticating with the Layer-0 auth code, and finally
|
||||
bringing the session fully online. Until this completes, nothing above it can work.
|
||||
Everything we have observed says the client currently never even *starts* this — see
|
||||
the transport finding below.
|
||||
|
||||
**Layer 2 — FUT / UTAS.** `SHAPE.` FIFA Ultimate Team specifically is served by the
|
||||
EASFC Blaze component *and* by UTAS, a separate HTTPS REST service
|
||||
(`utas.*.fut.ea.com`). Once a Blaze session exists, the FUT client authenticates to
|
||||
UTAS (`POST /ut/auth`) with the session credential to obtain a FUT session id, and
|
||||
only then does it load squad/club data. The FUT spinner in the screenshot lives at the
|
||||
*top* of this stack, but it cannot clear until Layer 1 is answered — so "minimal Blaze
|
||||
handshake" means **Layer 1**, and Layer 2 is a second, HTTP-shaped project that comes
|
||||
after.
|
||||
|
||||
---
|
||||
|
||||
## Where the client currently stalls — the transport finding
|
||||
|
||||
`CONFIRMED.` Across a full menu-plus-FUT-attempt session we observed **zero
|
||||
`getaddrinfo` calls and zero outbound sockets**, and — via the `ELEM_WATCH` probe — the
|
||||
game's per-connection message-handler dispatch container at `element[0]+0x40` stayed a
|
||||
clean, empty, default-constructed vector the entire time, including while the FUT
|
||||
spinner was on screen. `connectState.ctor` fired (the client builds connect-state
|
||||
objects) but registered nothing into that container.
|
||||
|
||||
The mechanical reading: **that container is populated by an actual Blaze message
|
||||
exchange** — handlers register as component notifications arrive during session
|
||||
bring-up (Layer-1 step 6 below). No Blaze reply → no handler registration → empty
|
||||
container → spinner spins forever. The spinner *is* the Layer-1 wall.
|
||||
|
||||
This leaves two possible transport situations, and **Milestone 0 exists solely to
|
||||
decide which one we are in** (see the Milestones section):
|
||||
|
||||
- **(a)** the client expects Blaze on a hardcoded local endpoint and would dial it if a
|
||||
listener were there, or
|
||||
- **(b)** the client only dials the Blaze redirector after an in-process bootstrap (the
|
||||
dial handler `0x144f4d360` `CONFIRMED`) fires — in which case the transport wall and
|
||||
the bootstrap wall are the same wall.
|
||||
|
||||
---
|
||||
|
||||
## Layer 1 — the minimal Blaze handshake ordering
|
||||
|
||||
Blaze is a framed binary protocol. Each message is a header — length, component id,
|
||||
command id, message type (request / response / notification / error), error code, and
|
||||
a message/sequence id — followed by a **TDF**-encoded body (EA's tag/type/value binary
|
||||
serialization). `SHAPE.` The exact numeric component/command ids and TDF field tags for
|
||||
FIFA 23's Blaze version are **UNKNOWN** until captured.
|
||||
|
||||
These are the six steps a responder must satisfy, **in order**, to bring a session
|
||||
online:
|
||||
|
||||
1. **`Redirector::getServerInstance`** `SHAPE` — the client asks the redirector for the
|
||||
address of the real Blaze server, naming the FIFA 23 service/SKU. The responder
|
||||
returns a `ServerInstanceInfo` TDF containing a **host:port** (point it at
|
||||
ourselves) plus an SSL flag. Without a valid address the client has nowhere to go.
|
||||
2. **connect + TLS** `CONFIRMED (bypass)` — the client opens a TLS connection to the
|
||||
returned address. Our ProtoSSL/cert-verify bypass is already in place, so our
|
||||
listener can terminate TLS.
|
||||
3. **`Util::preAuth`** `SHAPE` — the client sends its config/version/locale; the
|
||||
responder returns server config: the **component list**, ping-site list, telemetry
|
||||
settings (disable), and a misc config bundle. The client uses the component list to
|
||||
know what exists; an empty or malformed response here stalls it.
|
||||
4. **`Authentication::login`** `CONFIRMED (GetAuthCode feeds here)` + `SHAPE` — the
|
||||
client authenticates, presenting the **Nucleus auth code from Layer 0** (SSO). The
|
||||
responder returns the session: **BlazeId, session key, persona, entitlements**. A
|
||||
failure here is what surfaces as *"EA Servers are down."*
|
||||
5. **`Util::postAuth`** `SHAPE` — after auth, the client finalizes the session; the
|
||||
responder returns post-auth config (UserManager, association lists, telemetry,
|
||||
ticker/PIN).
|
||||
6. **`UserSessions::updateNetworkInfo` / `updateHardwareFlags`, then a
|
||||
`UserSessionExtendedDataUpdate` notification** `CONFIRMED (container is
|
||||
Blaze-downstream)` + `SHAPE (which command)` — the client publishes its network/
|
||||
hardware info and the server pushes extended session data. **The client flips to
|
||||
"online" on receipt of the extended-data notification** — and this is the exact
|
||||
moment the `element[0]+0x40` container we watched would begin filling, as handlers
|
||||
register for the arriving component notifications.
|
||||
|
||||
At step 6 the top-level "connected to EA" clears, and Layer 2 (UTAS) can begin.
|
||||
|
||||
### Why step 6 is the Milestone-1 success signal
|
||||
|
||||
The container-fill and the "online" flip are the *same event*: handlers register
|
||||
because Blaze notifications arrived. That gives blaze_brain a precise, already-built
|
||||
success detector. The first real win is **not** "full FUT works" — it is a single line
|
||||
in the hook log:
|
||||
|
||||
```
|
||||
ELEM_WATCH: [elem+0x40] CHANGED! …
|
||||
```
|
||||
|
||||
That line means the client accepted our Blaze replies and started registering
|
||||
handlers — i.e. steps 1–6 were convincing enough to bring the session online. The
|
||||
`ELEM_WATCH` probe that emits it is already written and deployed; it is our
|
||||
instrumentation for blaze_brain regardless of anything else.
|
||||
|
||||
---
|
||||
|
||||
## Milestones
|
||||
|
||||
- **M0 — transport reachability (this task).** Read-only. Confirm whether the client
|
||||
attempts *any* Blaze-flavored transport (situation a) or none at all (situation b).
|
||||
Gates every decision below. See the M0 section in the hook docs / launch notes.
|
||||
- **M1 — minimal session bring-up.** Stand up a listener at the M0-observed endpoint;
|
||||
answer `getServerInstance` (redirect to ourselves), then `preAuth` / `login` /
|
||||
`postAuth` with minimal valid TDFs and a single hardcoded persona. **Success signal:
|
||||
`ELEM_WATCH: CHANGED` fires and the spinner advances.**
|
||||
- **M2 — session online.** Handle the step-6 session notifications until the top-level
|
||||
"connected to EA" state is reached and stays.
|
||||
- **M3 — FUT / UTAS.** Implement the UTAS REST layer (`POST /ut/auth` and the
|
||||
`/ut/game/...` endpoints already sketched in `endpoint-map.md`) so FUT itself loads.
|
||||
|
||||
M1 is only reachable if M0 says the client actually dials a listener. If M0 comes back
|
||||
"no traffic" (situation b), M1 in its "answer over a wire" shape is blocked until the
|
||||
dial trigger is solved, and the strategic options are re-opened rather than a next task
|
||||
being obvious.
|
||||
|
||||
---
|
||||
|
||||
## Honest UNKNOWNs (capture before implementing)
|
||||
|
||||
- **Numeric component and command ids** for FIFA 23's Blaze version. The *names* and
|
||||
*ordering* above are `SHAPE`-reliable; the wire ids are `UNKNOWN`.
|
||||
- **TDF field tags and body layouts** for each request/response. `UNKNOWN` — every
|
||||
response body must be shaped from a real capture (or careful trial against the
|
||||
client's parser).
|
||||
- **The redirector/Blaze transport itself** — host, port, and whether it is remote,
|
||||
loopback, or a pipe. This is exactly M0's question and is `UNKNOWN` until M0 runs.
|
||||
- **Whether the client dials at all** without the in-process bootstrap firing — the
|
||||
situation (a) vs (b) question. `UNKNOWN` until M0.
|
||||
|
||||
Until M0 answers the transport question, the ordering above is designable but
|
||||
untestable: there is nothing to answer *to*.

# OpenFUT — Closure & Preservation Record
|
||||
|
||||
*A clean-room reverse-engineering effort to restore FIFA 23 Ultimate Team offline after
|
||||
EA's server shutdown (October 2025). This document records what was built, what was
|
||||
achieved, and the precise technical wall at which the effort concludes.*
|
||||
|
||||
**Status: the online/FUT route is closed at a characterized wall. The offline-menu /
|
||||
EA-App-emulation layer works and is preserved.**
|
||||
|
||||
**Provenance:** everything here derives from observing the running client's own behaviour —
|
||||
live memory reads, static disassembly of the shipped binary, and the game's responses to
|
||||
our synthesized inputs. No leaked EA source was used or referenced at any point. That
|
||||
clean-room discipline is the legal foundation of the work and is the reason this record can
|
||||
exist.
|
||||
|
||||
---
|
||||
|
||||
## 1. What OpenFUT set out to do
|
||||
|
||||
FIFA 23's online services were permanently shut down in October 2025, which removed FIFA
|
||||
Ultimate Team — the mode is backed by EA's online infrastructure and simply cannot start
|
||||
without it. OpenFUT's goal was game preservation: let a legitimately-owned copy run FUT
|
||||
against a **local, emulated backend** instead of EA's dead servers.
|
||||
|
||||
The intended shape was three cooperating pieces:
|
||||
|
||||
```
|
||||
FIFA 23 client (offline, under Proton/Wine or native Windows)
|
||||
│ EA-App / Blaze / FUT protocols
|
||||
openfut_hook.dll — injected; redirects EA traffic, bypasses cert pinning, observes
|
||||
│ localhost
|
||||
openfut-bridge — answers the EA-App (LSX) protocol; was to answer Blaze + FUT
|
||||
│
|
||||
openfut-core — the game-independent FUT economy backend (cards, packs, SBCs…)
|
||||
```
|
||||
|
||||
The entry sequence the client runs, in order, each gating the next:
|
||||
|
||||
1. **LSX** — the EA App ↔ game local handshake (login, entitlements, config).
|
||||
2. **Blaze redirector** — "where is my game server?"
|
||||
3. **Blaze preauth / login / postauth** — establish the online session.
|
||||
4. **FUT entry** — eligibility, then the FUT hub loads over REST.
|
||||
|
||||
The plan was to walk these gates one at a time, synthesizing each response and verifying it
|
||||
against the live client (the client is the oracle — a gate is "done" when the game advances).
|
||||
|
||||
---
|
||||
|
||||
## 2. What was achieved
|
||||
|
||||
This is preservation documentation, so the wins are recorded first and plainly. They are
|
||||
real, and they stand independent of the wall reached later.
|
||||
|
||||
### 2.1 Clean-room injection and TLS neutralization
|
||||
|
||||
- A `version.dll` / FLE-loaded hook that injects into FIFA 23 under Proton/Wine without
|
||||
tripping the (neutralized) anti-cheat, writing a durable log for observation.
|
||||
- ProtoSSL / cert-verify bypass sufficient to let the game accept our substituted
|
||||
endpoints at the layers we terminate.
|
||||
- Winsock interception (`getaddrinfo`, `connect`, `WSAConnect`, `ConnectEx`) with EA-host
|
||||
and EA-port redirection to the local bridge — including, by the end, **IPv6 (IPv4-mapped)
|
||||
redirection**, which closed a real leak the earlier IPv4-only path had missed.
|
||||
|
||||
### 2.2 The LSX / EA-App layer works — the game reaches a fully-authenticated menu offline
|
||||
|
||||
This is the substantive achievement. The bridge's native LSX server (port 3217) emulates
|
||||
the EA App / EbisuSDK local protocol completely enough that FIFA 23, with EA's servers gone,
|
||||
**boots to its main menu believing it is logged in and online.** Confirmed working, from the
|
||||
bridge's own logs of a live session:
|
||||
|
||||
- `EALS ChallengeResponse` — the EA login-service challenge/response handshake completes
|
||||
(`handshake complete`).
|
||||
- `EbisuSDK GetConfig / GetProfile / GetGameInfo / GetSetting` — all answered; the game gets
|
||||
its service list, profile, and configuration.
|
||||
- `Utility GetInternetConnectedState → connected=1` — the connectivity check passes.
|
||||
- `XMPP SetPresence → INGAME` — presence is set.
|
||||
- `Login IsLoggedIn=true` and `OnlineStatusEvent isOnline=true` — pushed continuously; the
|
||||
game's own online-status state flips to "online."
|
||||
|
||||
Everything the EA-App layer is asked for, it receives. This is a genuine, reusable
|
||||
clean-room EA-App/EbisuSDK emulator.
|
||||
|
||||
### 2.3 Reverse-engineering infrastructure
|
||||
|
||||
The effort produced durable tooling and knowledge, all clean-room:
|
||||
|
||||
- Live memory inspection via `/proc/<pid>/mem` (Wine maps `FIFA23.exe` flat at ImageBase
|
||||
`0x140000000`), including a stable algorithm to resolve the live Blaze connection manager
|
||||
(`G = *[0x14acd02c0]` → `M = *[G+0x360]` → `ctx = *[M+0x778]`; then a heap scan for the
|
||||
object `P` with `[P+0] == base+0x80200b8` and `[P+8] == M`).
|
||||
- Read-only in-process probes (menu-time snapshots, a write-watchpoint on the dispatch
|
||||
container, transport observation) — all env-gated, none altering game state.
|
||||
- Handshake-independent TLS **SNI capture** on the bridge (peek the ClientHello, parse SNI
|
||||
before the handshake, so the hostname is learned even when the client rejects our cert).
|
||||
- A documented **Blaze handshake reference** (`docs/blaze-handshake.md`) mapping the
|
||||
three-layer LSX / Blaze-core / UTAS model and the six-step Blaze session ordering.
|
||||
|
||||
---
|
||||
|
||||
## 3. The wall — reached from three independent directions
|
||||
|
||||
FUT never loaded. The reason is a single wall, and the strongest evidence for it is that
|
||||
three unrelated lines of investigation arrived at the same place.
|
||||
|
||||
### 3.1 The forcing arc (memory side)
|
||||
|
||||
We confirmed the live Blaze connection manager and the in-process "dial" handler
|
||||
(`0x144f4d360`) that begins the Blaze connection when the network comes online. Both exist at
|
||||
the menu. But:
|
||||
|
||||
- **Forcing the dial with the connection scaffold empty crashes** in normal `.text` (not the
|
||||
VM) at `0x144fd6b6c`: a binary search over a per-connection message-handler table whose
|
||||
`begin` pointer is an uninitialized sentinel (`1`). The table is empty because nothing has
|
||||
populated it.
|
||||
- **Forcing the online state machine to "fully online" (state 2) crashes the anti-tamper
|
||||
VM** deterministically — the game's own protected online code runs against a forced-but-
|
||||
absent session and faults. A forced state cannot substitute for a real session.
|
||||
|
||||
Conclusion of the arc: the dial and the online state are *primed but unpumped* — real
|
||||
infrastructure that only a genuine connection flow drives, and that cannot be safely forced.
|
||||
|
||||
### 3.2 The network / transport arc
|
||||
|
||||
With the entire EA-App layer satisfied (§2.2) and the network path fully instrumented
|
||||
(including IPv6 and SNI capture), we watched a complete FUT "connecting to EA Servers"
|
||||
attempt. The complete outbound inventory:
|
||||
|
||||
| Traffic | Identity | Fate |
|
||||
|---|---|---|
|
||||
| 2× IPv6 `:443` → `rl.data.ea.com`, `pin-river.data.ea.com` | EA **PIN/River telemetry** (fire-and-forget) | reached the bridge, **cert-rejected by ProtoSSL** |
|
||||
| 6× IPv6 UPnP (`:1900`, `:80`, LAN) | NAT traversal | — |
|
||||
| LSX (`:3217`) | EA-App layer | fully answered |
|
||||
|
||||
**No `gosredirector` / `redirector.ea.com`. No Blaze-port (`:42127` / `:10041`) connect. On
|
||||
any transport.** Starting FUT added *zero* new dials. The game is satisfied enough by the
|
||||
EA-App layer that it never attempts a Blaze connection at all. (This also corrected an
|
||||
earlier false belief — "zero outbound sockets" — which turned out to be undecoded IPv6
|
||||
traffic.)
|
||||
|
||||
Conclusion of the arc: the wall is **not** transport, **not** an unanswered LSX request,
|
||||
**not** the cert. The game simply never initiates Blaze.
|
||||
|
||||
### 3.3 The two arcs meet
|
||||
|
||||
The forcing arc found, from memory, that the connection scaffold is never populated. The
|
||||
network arc found, from the wire, that no connection is ever attempted. Same wall, two sides.
|
||||
The final chapter explains *why*, from the binary itself.
|
||||
|
||||
---
|
||||
|
||||
## 4. Final chapter — the dial-initiation gate (why it is circular)
|
||||
|
||||
This is the concluding technical result: a static reverse-engineering pass answering the one
|
||||
question both arcs left open — *beyond "online," what does the code check before it fires the
|
||||
Blaze dial, and is that condition reachable offline?*
|
||||
|
||||
### 4.1 Method
|
||||
|
||||
Read-only static analysis of the shipped `FIFA23.exe` (`objdump`), two cross-reference
|
||||
techniques: an 8-byte absolute-address search across the whole file (finds function pointers
|
||||
stored in data — vtables, tables) and a disassembly grep for `call`/`jmp`/`lea` targets
|
||||
(finds code references; a `lea reg,[…] # 0x…` is an address being *taken* for registration, a
|
||||
`call 0x…` is a direct invocation). Addresses below are `FIFA23.exe` virtual addresses
|
||||
(ImageBase `0x140000000`). The anti-tamper VM region `[0x14c1cd000, 0x160eb1000)` is
|
||||
unreadable; everything traced here is in normal `.text`.
|
||||
|
||||
### 4.2 The caller graph
|
||||
|
||||
```
|
||||
dial handler 0x144f4d360
|
||||
▲ address-taken only (lea r9,[dial]) — NEVER called directly, NEVER in a vtable
|
||||
│ inserted into the container [connMgr+0xc38] by:
|
||||
F1 registrar 0x144f4b7b0 (exactly ONE caller)
|
||||
▲
|
||||
F2 0x144f4b960 (builds a callback, calls F1 with rcx = connMgr)
|
||||
▲ TWO callers, identical guard: cmp bpl,[this+0x42] ; cmp bp,[this+0x142]
|
||||
├── F3a 0x144f44770
|
||||
└── F3b 0x144f4bbf0
|
||||
```
|
||||
|
||||
Every reference is a normal-`.text` `lea` — the dial handler is *registered as a callback*,
|
||||
never called by address. The registrar `F1` is a "get-or-create into the message-handler
|
||||
container": on a miss it allocates a handler and copies a caller-supplied callback into it.
|
||||
Its sole caller `F2` supplies the callback and resolves the connection manager
|
||||
(`rcx = [[this+8]+0xca0]`).
|
||||
|
||||
### 4.3 The decisive structural fact
|
||||
|
||||
`F3a` and `F3b` — the two functions that actually decide to register the dial — are, from the
|
||||
whole-binary sweep, **in zero vtables and never directly called.** They are `lea`'d at four
|
||||
sites and **registered into `[connMgr+0xc38]`, each keyed by a `.rdata` message-type
|
||||
descriptor** (`0x1483fcf98`, `0x14808d7d0`). In other words they are themselves **message
|
||||
handlers**, dispatched indirectly by the connection manager when a matching Blaze message
|
||||
arrives — not methods invoked by a state machine you can drive locally. (In Rust terms: not
|
||||
methods on a trait object, but closures inserted into a `HashMap<MessageType, Handler>` and
|
||||
called by a dispatcher.) The functions that register *them* (`G_a 0x144f4a350`,
|
||||
`G_b 0x144f45220`) are ordinary helpers inside the same cluster, and the entire cluster
|
||||
`F1…G_b` is vtable-free.
|
||||
|
||||
So the whole thing is one **self-registering, message-driven state machine on
|
||||
`[connMgr+0xc38]`:** each handler fires when its Blaze message arrives, checks connection
|
||||
state, and registers the next handler — until `F3a`/`F3b` register the dial. The state each
|
||||
step checks (`[this+0x42]`, `[this+0x142]`, …) is connection-lifecycle state, advanced only
|
||||
as messages are processed.
|
||||
|
||||
### 4.4 Reachability, and why it is circular
|
||||
|
||||
Offline, the container `[connMgr+0xc38]` is **empty** (measured directly: the crashing table's
|
||||
`begin` is `0`/garbage; the network arc saw zero Blaze messages). Nothing ever dispatches
|
||||
`F3a`/`F3b`, so their guards never even execute — the wall sits *upstream* of them. The one
|
||||
thing that does fire offline is the connection-state constructor (on the online-status event),
|
||||
so the machine's entrance is *partially* reached and then stalls immediately, because no
|
||||
Blaze message follows to drive the first dispatch.
|
||||
|
||||
**Outcome: circular gate.** The trigger is *found* — we can see precisely how the dial gets
|
||||
registered and fired. But its precondition is *prior Blaze connection-lifecycle messages
|
||||
having populated and dispatched the handler container* — i.e. the very network exchange the
|
||||
connection is meant to produce. The state that gates the dial requires the dial's own earlier
|
||||
connection steps to have already run. It is not a settable flag (there is none between
|
||||
"online" and "dial"); it is an entire message exchange that never begins.
|
||||
|
||||
This is the exact mechanical explanation of both arcs: the container is empty because no
|
||||
messages flow (network arc), and forcing the dial into that empty container crashes (memory
|
||||
arc).
|
||||
|
||||
---
|
||||
|
||||
## 5. What this means — the boundary, stated plainly
|
||||
|
||||
**OpenFUT can take FIFA 23 to a fully-authenticated main menu, offline, believing it is
|
||||
logged in and online — but it cannot take it into FUT.** FUT requires a Blaze session, and on
|
||||
this build the Blaze connection is never initiated. The bootstrap is circular: the client
|
||||
will only walk its connection state machine as real Blaze messages arrive, and no messages
|
||||
arrive because no connection is begun. "Online," at the EA-App level, is genuinely
|
||||
disconnected from "reach out to Blaze," and the gap between them is not a flag we failed to
|
||||
set — it is a live protocol exchange that has no counterpart to talk to.
|
||||
|
||||
Two secondary walls sit behind the first, and would matter only if it were solved:
|
||||
|
||||
- **ProtoSSL cert pinning** (`CertificateUnknown`) rejects our self-signed cert on the
|
||||
DirtySDK path — so even redirected EA HTTPS cannot complete a handshake as-is.
|
||||
- **The anti-tamper VM** faults deterministically whenever forced state is used by the game's
|
||||
own protected online code — so "force the state and let the game run" is not viable.
|
||||
|
||||
---
|
||||
|
||||
## 6. Paths not taken, scoped honestly
|
||||
|
||||
Only one route could still reach FUT, and this record scopes it so the decision is clear-eyed
|
||||
rather than reopened casually.
|
||||
|
||||
**In-process Blaze state-machine injection.** Rather than answer Blaze over a wire (there is
|
||||
no wire — the game never dials), blaze_brain would **drive the game's in-process connection
|
||||
state machine by injecting synthesized Blaze response frames into its dispatch layer.** From
|
||||
the final-chapter RE, that requires:
|
||||
|
||||
1. Making the connection appear *initiated*, so the game registers its first response handler.
|
||||
2. Feeding synthesized Blaze responses **in order and keyed to the same `.rdata` message-type
|
||||
descriptors**, so each registered handler fires, advances the connection-state flags, and
|
||||
registers its successor — walking the machine forward until the dial is registered and
|
||||
fires.
|
||||
|
||||
This is a weeks-scale build requiring per-message protocol RE done from the *receive* side,
|
||||
against a client that is the only available oracle (the servers are dead, so every frame must
|
||||
be synthesized and validated by whether the client advances). It also inherits an unsolved
|
||||
sub-problem: the initial "connection initiated" state must itself be synthesized or forced,
|
||||
since the game does not produce it offline. It is possible in principle; it is not a small
|
||||
task, and its scope should be understood before it is begun.
|
||||
|
||||
The alternative — the one this document records — is to treat the fully-authenticated offline

## 7. Preservation value
|
||||
|
||||
Even without FUT, the effort produced things worth keeping:
|
||||
|
||||
- **A working clean-room EA-App / EbisuSDK (LSX) emulator** that boots FIFA 23 to an
|
||||
authenticated main menu with no live EA servers — a genuine preservation artifact for the
|
||||
offline single-player state.
|
||||
- **A documented map of exactly where and why online play is unreachable** on this build,
|
||||
grounded in the binary: the dial caller graph, the message-driven container mechanism, and
|
||||
the circular bootstrap. Future work (on this title or the engine family) starts from a
|
||||
known wall, not a blank page.
|
||||
- **Reusable RE tooling and references** — live-memory resolution of the connection manager,
|
||||
the transport/SNI instrumentation, and the Blaze handshake reference doc.
|
||||
- **A clean provenance record** — nothing derived from leaked source, so the work remains
|
||||
usable and shareable.
|
||||
|
||||

|
||||
|
||||
## 8. Closing note
|
||||
|
||||
OpenFUT reached the last gate it could reach without a live server to talk to, and then
|
||||
proved — from memory, from the wire, and from the binary — that the next gate is not a lock
|
||||
we failed to pick but a door that only opens from the far side. That is a complete and honest
|
||||
result. The offline menu stands; the map is drawn; the wall is named.
