khallaandClaude Opus 5.5 d9f5c85430 Initial sacred_re scaffold with borderless fullscreen mod

- Launcher (sacred_re.exe) starts sacred.exe with sacred_re.dll injected
  via Detours; the DLL verifies the Sacred Gold 2.28 build before hooking.
- Hook framework: RE_HOOK for game addresses, RE_HOOK_API for Windows
  APIs, per-hook enable/disable in sacred_re.ini, sacred_re.log.
- Game code: Log (0x66f1c0) hooked, CmdLineHasFlag (0x813140) rewritten.
- Borderless mod: forces windowed mode, covers the monitor, scales the
  1024x768 image aspect-correct, remaps mouse input, keeps running in the
  background with keyboard input hidden while unfocused.
- CMake/Ninja/MSVC x86 build, VS Code setup, disasm tool, function map.

Function map

Addresses are sacred.exe virtual addresses (image base 0x400000).

Status: rewritten (our code replaces the original), hooked (our code wraps the original), identified (purpose known, not touched yet).

Startup

Address	Name	Conv.	Status	Notes
`0x0084c704`	`entry`	—	identified	MSVC 6 CRT startup (`WinMainCRTStartup`)
`0x00816bd0`	`WinMain`	stdcall	identified	single-instance mutex `SACRED_INSTANCE`, OS check, logging setup, `Settings.cfg`, language selection, main window, message loop, shutdown
`0x00813240`	`CreateMainWindow`?		identified	"WinMain : unable to create main window" on failure
`0x00815620`	`InitGame`?		identified	"WinMain : initialization failed" on failure

Engine

Address	Name	Conv.	Status	Notes
`0x0066f1c0`	`Log`	cdecl, varargs	hooked	printf-style; writes `DEBUG.LOG` when enabled; see `src/game/engine/log.cpp`
`0x0066ed80`	`SetLogEnabled`	cdecl	identified	sets byte `0x017e5ee0`
`0x0066ef60`	`OpenLogFiles`	cdecl	identified	(re)opens `DEBUG.LOG`, `ExpLog.LOG`
`0x00813140`	`CmdLineHasFlag`	cdecl	rewritten	`src/game/engine/cmdline.cpp`
`0x00813240`	`CreateMainWindow`	cdecl	identified	registers class "Sacred" (wndproc `0x008122a0`), `WS_POPUP\|WS_VISIBLE` screen-sized window unless `win` flag
`0x008122a0`	`MainWindowProc`	stdcall	hooked	borderless mod remaps mouse message coordinates
`0x0066e500`	`GetMouseClientPos`	cdecl	hooked	`GetCursorPos` relative to client area; borderless mod maps to game pixels
`0x00610650`	?	thiscall	identified	player input; only `SetCursorPos` caller (cursor nudging)

Renderer (`dxDriver7`, instance pointer `0x00cda99c`)

Layout: src/game/render/dx_driver7.h.

Address	Name	Conv.	Status	Notes
`0x00645390`	`DxDriver7::SetDisplayMode`	thiscall, `ret 0xc`	hooked	args (deviceCaps, `DxDisplayMode*`, ?); borderless mod forces windowed + resizes window
`0x00645f70`	`DxDriver7::Flip`	thiscall	hooked	windowed: `primary->Blt(+0x1ec, back, +0x1dc)`; borderless mod sets both rects
`0x00645000`	`DxDriver7::CreateZBuffer`?		identified
`0x00644be0`	`DxDriver7::CreateSurface`?		identified

Globals

Address	Type	Name	Notes
`0x017e5ee0`	`bool`	`g_logEnabled`	set by `log` flag
`0x017e5ed4`	`FILE*`	`g_debugLog`	`DEBUG.LOG`
`0x017e5ed8`	`FILE*`	`g_expLog`	`ExpLog.LOG`
`0x017e5ee4`	`void()(const char)`	`g_logCallback`
`0x017e5cb4`	`int`	`g_language`	index into code table `0x00897394` (US DE FR SP IT PL HU JP VC RU CZ, 16-byte stride)
`0x0182cd38`	`HANDLE`	`g_instanceMutex`
`0x00cda99c`	`DxDriver7*`	`g_dxDriver`
`0x0182cdb8`	`uint32_t`	`g_appFlags`	bit `0x20000` = app inactive (set/cleared on `WM_ACTIVATEAPP` at `0x00812421`)
