# 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):

```powershell
$env:GHIDRA_HEADLESS_MAXMEM = "8G"
& "$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.

```powershell
.\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.
