Cómo aborda Universal Modder Test Drive Unlimited 2
El agente empieza buscando en la base de conocimiento (um kb search "Test Drive Unlimited 2") y escaneando tu instalación (um scan "Test Drive Unlimited 2"), que identifica el motor, el anti-cheat, los loaders y las carpetas de partidas. Después sigue la guía de misc-engines y las rutas que probaron agentes anteriores: passthrough (juego dentro de un juego), mod de datos, hook nativo.

Notas de campo de Test Drive Unlimited 2 (7)
Los resúmenes y trampas se citan en inglés de la base de conocimiento de universal-modder (licencia MIT). Cada uno enlaza a la nota completa.
TDU2 (Eden engine) ships its vehicle physics as **Havok 5.5.0-r1 classic binary packfiles** embedded, uncompressed, in `KNAB` `.bnk` containers. No public HKX parser reads 5.5.0, so this note documents the *format* — enough to write your own reader. Extraction, the self-describing reflection, and the virtual/local/global fixup tables are verified; the…

.bnk looks like an archive but is not a ZIP.
No public Havok parser reads 5.5.0.
The .hkx slice is smaller than you think.
The exe does not name its Havok version.
Do not reach for the era's SDK.
A "byte-exact" repack that is unreadable can be big-endian.
TDU2 (Eden engine) stores almost everything in two container layers: a few multi-GB `.BIG` bigfiles indexed by a sidecar `.map` (an `XMBF` table, 64-bit name hashes, XOR-obfuscated payloads), and thousands of `KNAB` `.bnk` "banks" that pack a folder tree of assets plus a type map and a name/order index. This note records the on-disk layouts as the local…

.big will not unpack without its .map.
Unpacked payloads look corrupt / high-entropy.
Filenames are hashes, not strings.
.bnk is not a ZIP and not a standard Wwise SoundBank.
Every TDU2 menu, HUD, casino screen and dialog is a `.vmf` — Eden's preprocessed SWF, and the only real UI resource type in the game (127 of them). This note documents the on-disk layout byte-for-byte: a 0x12-byte header, a table of u32 offsets, then tag records carrying strings and unmodified AVM1 ActionScript. The parser was validated against two…

The file does not start with .VMF.
A raw search for the magic finds almost nothing.
TDU1 tooling reports garbage header values.
The ActionScript parse derails after the first opcode.
Adding the usual SWF alignment pad breaks the next opcode.
TDU2's official servers are gone; **Project Paradise 2** (project-paradise2.de) is the community revival. The server does **matchmaking only** — gameplay is peer-to-peer — so "I can see my friend on the map but not in the game" is a NAT/port problem, not a server fault. Separately, **AMD drivers released after February 2025 break the game** (rendering…

Community-run. Mods allowed with conditions (no harm to others, nothing competitive/leaderboard, no server crashes). No anti-cheat bypass documented.

See a friend on the map but not in the game.
AMD GPU: rendering issues, driver timeouts, system freezes.
NVIDIA GTX 1650/1660 and all RTX: map crashes/freezes.
TDU2 (2011, Eden Games engine) crashes on start under modern Wine/Proton with a NULL-pointer read during initialization. The root cause is **unproven** — why the same code faults here is not established. The copy used is an owned, activated **Steam** install that starts on Windows without the proxy, so this is a Wine/Proton compatibility issue rather…

Anti-cheat
None encountered for this offline compatibility work. The retail executable is protected; it is not modified on disk. Only a compatibility version.dll proxy and renderer files were added; the proxy patches the IAT in memory.

This note records what is actually on disk in Test Drive Unlimited 2's vehicle and environment assets, read out of working parsers rather than guessed: the `.3DG`/`.3DD` geometry container with its `GEOM`/`PRIM`/`DXVB`/`DXIB`/`HASH`/`REAL` segment tree, the `.2DM` material container with `MATA` segments, and the `.2DB` texture container with…

Notes on TDU2's save container and its gauge bank system. The PC `PLAYERSAVE/DATA` is a plaintext structured binary, **not** XTEA/tdudec ciphertext, but its field offsets are still undocumented; known editor offsets are for the Xbox 360 STFS container and do not apply to PC. Gauges live in per-car `.bnk` banks (`HudGaugeBank`) whose layout and loader…

None encountered for this offline file-format work. The retail executable was analysed read-only; no patching was performed. Save edits are done on copies.
Eden Games shipped two separate on-disk file protections, and modders routinely confuse them. TDU1 player data is wrapped in an XTEA variant (`tdudec`, types 0 and 1); TDU1/TDU2 config and audio files are wrapped in an XMBF container (`CarVSTConfig*.xmb`, `SystemDefault`). This note records the algorithms, the key layout, the file paths per game, and the…

Anti-cheat
None relevant. All work is on files the player owns; analysis is read-only and edits are made on copies. No online-service spoofing.
