OpenFUT FIFA 17 - native Windows client

The FIFA 17 client host (10.10.0.105, Windows 11 Pro) runs FIFA 17 natively (no Wine/Proton/umu). This directory holds the read-only preflight verifier and documents the native launch/routing/rollback model.

Install layout (`C:\FIFA 17`)

File	Role
`FIFA17.exe`	retail game exe (sha256 `29C31CEF…`). Never modify/patch. ImageBase `0x140000000`.
`_fifa17.exe`	native crack loader (Chemicalflood). This is what you launch. `asInvoker` manifest -> must be elevated externally.
`version.dll`	OpenFUT hook (in-process via the version.dll load-order hijack). ImageBase `0x180000000`.
`version.dll.stale-849k.bak`	rollback copy of the previous hook.
`CardsDLL_Win64_retail.dll`	FUT card/SBC/kit logic. ImageBase `0x180000000`.
`powdll_Win64_retail.dll`	Pack-Opening-World (EASFC store). ImageBase `0x180000000`.
`sysdll_Win64_retail.dll`	EA networking / ProtoSSL (cert, ea.com).
`stp-origin_emu.dll` + `stp-origin_emu.ini`	Origin/LSX login emulator (in-process; opens LSX `:4216` locally at runtime). Persona configured in the `.ini`.
`stp-selector.exe`	ssl/LSX selector companion.
`openfut.cfg`	operator-facing routing override (see below).

Launch (native - there is NO launcher script by design)

Run C:\FIFA 17\_fifa17.exe as Administrator. The correct, reproducible way:

Double-click the "FIFA 17 (OpenFUT)" shortcut (Desktop and Start Menu). It targets _fifa17.exe, working dir C:\FIFA 17, with the RunAsAdmin bit set.
_fifa17.exe is also flagged RUNASADMIN in HKCU\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers, so any launch (Explorer double-click included) elevates via UAC.

On launch the Windows loader maps version.dll from the game directory (hijack), stp-origin_emu.dll emulates Origin login for the configured persona, and the hook redirects EA endpoints to the OpenFUT backend.

Do not wrap the launch in a script. The elevation + shortcut is the supported mechanism. FIFA under native Windows also ignores synthetic input, so in-game steps are performed by the operator one at a time.

OpenFUT Launcher (GUI)

The openfut-launcher egui app runs natively on Windows (built for x86_64-pc-windows-gnu; the Linux Proton path is cfg-gated out). It is the one-button front end: it checks the backend, reconciles openfut.cfg from its settings, and starts the game.

Binary: C:\OpenFUT\openfut-launcher.exe; config: %APPDATA%\openfut-launcher\config.json.
Launch it from the "OpenFUT Launcher" shortcut (Desktop / Start Menu). The launcher itself is flagged RUNASADMIN, so it elevates once at start; the game it spawns inherits that elevation (no second UAC prompt, no crack loader "run as admin" failure).
On Windows the launcher does NOT spawn LSX/autopatch (they are in-process: stp-origin_emu.dll + the version.dll hook) and does NOT arm the host (routing is purely openfut.cfg, which it writes into C:\FIFA 17).
Rebuild from Linux: cargo build -p openfut-launcher --release --target x86_64-pc-windows-gnu.

Routing (`openfut.cfg`)

host=10.10.0.120
https_port=8443
blaze_redirector_port=42127
blaze_main_port=42130

The hook carries 10.10.0.120 as its baked-in default; openfut.cfg is the override. 10.10.0.120 hosts both production and staging.

Production safety: blaze_main_port=42130 is the production Blaze. Before any match/economy exercise, repoint blaze_main_port (and the matching UTAS/HTTPS route) to the staging port so no traffic reaches the prod container. The preflight raises a WARN whenever 42130 is configured.

Rollback

The hook is a single file swap; no installer state.

# disable OpenFUT hook (restore previous DLL)
Copy-Item 'C:\FIFA 17\version.dll' 'C:\FIFA 17\version.dll.disabled.bak' -Force
Copy-Item 'C:\FIFA 17\version.dll.stale-849k.bak' 'C:\FIFA 17\version.dll' -Force
# re-arm: copy the desired hook build over version.dll again

Always keep a *.bak of the live hook before redeploying (the preflight checks that a rollback backup exists and differs from the live DLL).

Preflight

openfut-client-preflight.ps1 is read-only: it never launches the game, never elevates, never writes game files, never mutates economy state. It verifies the retail exe hash, companion DLLs, hook + rollback, routing + backend reachability, login persona, launcher elevation, and the RE toolchain (x64dbg, cargo). Exit 0 = OK, 1 = blocking failure.

Runtime RE (x64dbg)

See the Vault note 02 Reverse Engineering/FIFA 17/Windows Client Runtime & x64dbg.md for the attach workflow and the RVA<->VA (ASLR) math. In short: these modules' preferred ImageBase is 0x180000000 (0x140000000 for FIFA17.exe); in x64dbg a module name evaluates to its runtime (ASLR) base, so a Ghidra address maps to a breakpoint as bp CardsDLL_Win64_retail.dll+<RVA> where RVA = ghidra_addr - 0x180000000.
