Ported from sacredK with module-relative addresses, hooks by exported name and a SHA-256 check of the six game modules (Community Patch 2.65.1). Borderless windowed at monitor size replaces exclusive fullscreen, whose focus loss during loading made the game quit and crash on exit. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# Game modules
|
|
|
|
Surveyed 2026-10-31 on Sacred 2 Gold (Steam) with Community Patch 2.65.1.
|
|
|
|
`sacred2.exe` (client, UI) statically imports the game DLLs, so all of them are
|
|
mapped before our DLL's `DllMain` runs. All DLLs prefer image base 0x10000000
|
|
and none is ASLR-enabled; the loader relocates all but the first, so their
|
|
running bases differ from Ghidra's. `re::Address{module, va}` holds the
|
|
Ghidra VA and resolves it at runtime; `sacred2K.log` lists the running bases.
|
|
|
|
| Module | Role | Exports | Notes |
|
|
|---|---|---|---|
|
|
| `sacred2.exe` | client: main loop, UI, input | 1 | image base 0x400000, sections `.text .rdata .rdata .data .data .rdata .common .rsrc`; "linker 4.0", PE date 2010 (modified by the Community Patch) |
|
|
| `orcSystem.dll` | "Orc" engine base: `Orc::String`, `Log`, `LogManager`, files, timers, singletons | 3231 | 2009-07 |
|
|
| `s2core.dll` | shared types: kernel events (`cEvent*`), world/sector positions, waypoints, type manager | 1966 | |
|
|
| `s2logic.dll` | game logic: creatures, items, quests, dialogs, factions, drops, balance (`cLogicMgr`, `c*Mgr` singletons) | 5398 | |
|
|
| `s2logicai.dll` | AI | 176 | |
|
|
| `s2render.dll` | renderer (D3D9, Granny, PhysX) | 2258 | |
|
|
|
|
Other modules, not in the build check yet: `s2logicdll.dll`, `s2editor.dll`,
|
|
`s2vista.dll`, the `plugin_*.dll` set from `plugins.cfg` (file system, zip,
|
|
particle FX, Bink, Miles, OpenAL; loaded at runtime), third-party libraries
|
|
(`granny2`, `binkw32`, `mss32`, PhysX, `stlport.5.0`, MSVC 8 runtime). `s2gs.exe`
|
|
is the dedicated server.
|
|
|
|
Toolchain: MSVC 8 (VS 2005), STLport 5.0 strings and containers, C++ classes
|
|
exported with decorated names (`?method@Class@@...`), so most functions of the
|
|
DLLs are named. `tools/exports.mjs` lists them; Ghidra demangles them.
|
|
|
|
## Orc::String
|
|
|
|
STLport string with a 16-byte inline buffer, 0x18 bytes; see
|
|
`src/game/orc/string.h`.
|
|
|
|
## Data
|
|
|
|
`pak\*.zip` (graphics, sectors, sound), `scripts\` (client/server/shared Lua-like
|
|
text configs), `locale\de_DE` (German texts `global.res`, item name CSVs,
|
|
speech). User options: `%LOCALAPPDATA%\Ascaron Entertainment\Sacred 2\options.txt`.
