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…

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

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 (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…

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.

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.
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…
