- Default render size is 768 high and as wide as the monitor aspect
(1835x768 on 3440x1440), scaled up: everything keeps the size players
know and the view only grows sideways. Height=0 keeps native 1:1.
- Ground: 818/888 clip limits, screen centre floats and integer
immediates, ground quad list (capped at 1749) moved with the tile list.
- 3D: cGranny ortho (+-512 x +-384, incl. HUD items) scaled; inverse
projection 0x623a20 (1/1024, 1/768) follows the render size, which fixes
the camera following the player ("outside world") and the missing
player / ESC menu.
- tools: game-input.ps1 + autotest-load.ps1 drive the game (load the first
save game, screenshots in-game and with the ESC menu).

# 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.
