- potioncounts.cpp: each potion slot shows how many potions of its kind the hero carries (stacks added up) - potionstack.cpp: potions of one type stack up to 20 per cell; every potion entering the hero's grid pours into stacks with room, the sort button stacks first, drinking takes one off a stack, counts drawn on the cells and saved in the JSON inventories - game/engine/items.h: potion kinds and grid helpers; ObjectManager and DestroyObject in objects.h - auto-attack: the projectile-weapon target radius is a design value - docs/potion-stacks.md: measured paths and the design Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
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/ |
rename.ps1 |
apply the function names in names.txt to the Ghidra project (add names there as functions are identified) |
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, hold key,
screenshot). Don't touch mouse/keyboard while a test runs.
