The default render size (1835x768) is below Direct3D 7's 2048 limit, so the D3D7 -> D3D9 wrapper and its device-info workaround are no longer needed. The game pauses start-up until its window is active; game-input.ps1 now activates it reliably (Alt + SetForegroundWindow, polled), which dxwrapper had masked. borderless logs the first failed presents.

tools
Node tools need npm install here once (iced-x86). Paths to sacred.exe are
passed explicitly.
| Tool | Purpose |
|---|---|
disasm.mjs <exe> <va> [n] |
disassemble at an address, ignoring Ghidra's function boundaries |
find-imm.mjs <exe> <value...> |
every instruction using an immediate value (e.g. 1024 768) |
find-imm.mjs <exe> /regex/ |
every instruction whose text matches (e.g. /96AB0h\]/) |
rtti.mjs <exe> <Class> |
vtables of an MSVC class via RTTI |
decompile.ps1 <addr...> |
decompile from the persistent Ghidra project ghidra/ |
Persistent Ghidra project (ghidra/, not in git)
Created once (about 7 minutes):
$env:GHIDRA_HEADLESS_MAXMEM = "8G"
& "$env:GHIDRA_INSTALL_DIR\support\analyzeHeadless.bat" ghidra sacred -import "<Sacred Gold>\sacred.exe"
& "$env:GHIDRA_INSTALL_DIR\support\analyzeHeadless.bat" ghidra sacred -process sacred.exe -scriptPath tools\ghidra -postScript ApplyRtti.java
ApplyRtti.java recovers the MSVC 6 RTTI that Ghidra's own script misses:
410 vtables, ~1200 extra functions, methods named Class::vfNN.
Automated in-game test
autotest-load.ps1 starts the game through the launcher, clicks
"Spiel laden" -> "Laden" -> "Ok" (first save game), takes screenshots in-game
and with the ESC menu open, and stops the game. -Ini appends temporary
settings to build\x86-debug\sacred_re.ini (restored afterwards), e.g.
.\tools\autotest-load.ps1 -Name ws_off -Ini "[widescreen]`r`nEnabled=0"
Click positions assume the classic menu layout scaled onto a 3440x1440
monitor. game-input.ps1 has the building blocks (start, click, key,
screenshot). Don't touch mouse/keyboard while a test runs.
