MACS2: Fix sprite scaling loop logic in DrawSpriteAdvanced
Move xScaling/yScaling increment and target position advance before
the do-while loops to fix the scaling pixel repeat/skip logic.
Change hardcoded scaling value from 0x64*3 to 26.

MACS2: Implement AdLib music playback functions
Add Func24FD, Func2839, and OnTimer for AdLib music event processing.
Switch from port-based writes to writeReg(). Load music data from
resource file and start OPL timer callbacks. Add debug logging for
OPL register writes.

MACS2: Add script variables and callback-based execution loop
Add ScriptVariable struct with array storage. Implement requestCallback
mechanism to allow script execution to yield and resume. Fix Adlib
Func1A03 seek logic. Initialize variables array in ScriptExecutor
constructor. Add hardcoded test for music data parsing.

MACS2: Improve script executor opcode handling
Fix ScriptUnimplementedOpcode macro to print actual value. Add handler
for Func9F4D value 0x7. Implement FuncC8E4 with throwaway reads.
Add continue after FuncA3D2 call and handle additional loop conditions.

MACS2: Connect script executor to engine and implement area lookup
Store engine pointer in ScriptExecutor. Add Func101D for looking up
area IDs from the pathfinding map at character position. Implement

MACS2: Fix object data addressing and add blob loading skeleton
Fix address offset calculation for object table by accounting for
the 0776/077C globals before the 3000h data block. Add inner loop
skeleton for loading object blobs at l0037_0A3E.

MACS2: Implement scene script loading and character system
Add Scenes::ReadSceneScript() to load per-scene scripts from the
resource file. Create Character class in View1 with position, lerping,
and animation frame support. Refactor object loading to read blob
data with proper size handling.

MACS2: Add Func9F4D value 0x6 and 0x2F handlers
Implement value 0x6 returning constant 1 (game state flag) and
value 0x2F returning hardcoded current scene ID. Remove dangling
else clause for unhandled values. Add string box rendering in View1
draw loop.

MACS2: Implement scene string loading and speech act system
Add Scenes::ReadSceneStrings() to load per-scene string data. Add
ShowSpeechAct() to View1 for displaying character dialogue with
portrait. Implement opcode 0x0d for triggering speech acts from
script. Load scene strings during initialization.

MACS2: Implement opcode 0x0d dialogue display with portrait
Wire up opcode 0x0d to decode scene strings and call ShowSpeechAct
with character index, position, and side. Draw speaking character's
animation frame during string box display. Remove unused test string
decode call.

MACS2: Add RegisterWaitForMovementFinishedEvent and fix opcode 0x11
Implement RegisterWaitForMovementFinishedEvent() to handle the case
where movement may already be finished. Fire script continuation
event even when not currently lerping. Fix portrait blob index for
additional character IDs.

MACS2: Add timer system, Func9F4D value 0x31, and opcode 0x07
Add timer-based delay support with isTimerActive and timerEndMillis.
Implement Func9F4D value 0x31 stub. Add Func9F4D_Placeholder() helper.
Add opcode 0x07 no-op handler. Implement timer delay opcode for
script pausing.

MACS2: Add inventory item serialization and script variable resize
Serialize inventory items in save/load by object index. Change
script variables from fixed 10000 to resizable array of 1000.
Add SetVariableValue() helper. Implement opcode handlers for
additional script operations.

MACS2: Add Adlib::Deinit and implement script opcodes 0x20-0x22
Add Adlib::Deinit() to stop OPL and free resources, called from
engine destructor. Add stub handlers for opcodes 0x20 (y-offset),
0x21 (upward motion), and 0x22 in the script executor.

MACS2: Implement scene change with background image loading
Add changeScene() that loads background image via RLE decoding,
palette, and scene script/strings for a given scene index. Add
DEBUG_RLE debug channel for verbose RLE logging. Implement scene

MACS2: Remove legacy script execution code from engine
Remove the old ExecuteScript(), ScriptPrintString(), and related
helper functions from macs2.cpp that have been superseded by the
ScriptExecutor class. Remove unused _scriptData and _scriptStream
members.

MACS2: Implement dialogue choice system (opcodes 0x15-0x17)
Add opcode 0x15 to clear dialogue choices, 0x16 to add a choice
with decoded strings, and 0x17 to display the dialogue options.
Add DialogueChoices array to ScriptExecutor and ShowDialogueChoice()
stub to View1.

MACS2: Implement scene map loading and hotspot interaction setup
Load the actual background map (offset 0x0024B0DF) for hotspot
detection. Read additional RLE maps during scene change for depth
and walkability. Add SetVariableValue() and implement dialogue
choice result variable writing. Load scene-specific map data in
changeScene().

MACS2: Implement background hotspot detection
Add GetInteractedBackgroundHotspot() that looks up pixel value from
the background map and matches against hotspot arrays. Load hotspot
data (array5023, word50D3, array50D5) during scene change. Fix
palette/unknownData1 array allocation with resize() instead of
reserve().

MACS2: Fix hotspot detection array sizes and lookup logic
Increase array5023 size from 0xa to 0xa0 bytes. Add array50D5 loading
(0x20 bytes). Fix hotspot lookup to use array50D5 with 1-based index
adjustment. Change numHotspots type to uint16_t.

MACS2: Replace CursorMode with script MouseMode and fix Talk interaction
Remove engine-level CursorMode enum, using ScriptExecutor's MouseMode
directly. Implement Func9F4D value 0x3 to return interacted object ID
when in Talk mode. Fix NextCursorMode cycling logic.

MACS2: Implement inventory item removal and add is_in_list helper
Handle scene ID 0 in opcode 0x0b to remove items from inventory.
Add is_in_list template helper for cleaner multi-value comparisons
in GetCurrentPortrait(). Add chosenDialogueOption to script executor.

MACS2: Add shading table, dialogue option result, and fix inventory removal
Load shading table (0x100 bytes) during scene change. Add Func9F4D
value 0x0d handler returning chosenDialogueOption. Fix inventory
removal to use foundIndex > 0 check. Store dialogue choice in
script executor.

MACS2: Implement helper opcode 0x2A, fix opcode2 0x3 comparison, and add object parenting
Add stub for helper opcode 0x2A (inventory stack check). Fix opcode2
0x3 to use proper two-byte comparison. Implement object parenting
for scene IDs above 0x400.

MACS2: Add script execution state tracking and fix interaction handling
Add ScriptExecutionState enum to track scene vs object script execution.
Pass interactedOtherObjectID in Func9F4D Use mode. Rewind to scene
script after execution completes. Fix timer wait to return proper result.

Commit Message:
MACS2: Add lastOpcodeTriggeredSkip tracking and SIS_Debug helper
Track whether the last opcode triggered a skip in FuncA3D2. Replace
debug() calls with SIS_Debug() wrapper in script executor. Clean up
debug output formatting.

Enable proper animation frame selection using animationIndex modulo
numAnimations. Add stub for script opcode 0x32 (object field write).
Use orientation-based blob index for character rendering.

MACS2: Fix Func27E4 to use proper array and Func2792 calls
Replace raw pointer access with gArray69 lookup and Func2792.
Add gArray69 to header. Clean up OnTimer entry comments.

MACS2: Major Adlib OnTimer restructuring and Func2686 integration
Restructure the OnTimer function flow, integrate Func27E4 closing
brace, add g2258 initialization, and reorganize the main event
processing loop indentation.

Commit Message:
MACS2: fix all compiler warnings
- Fix sign-compare warnings by using uint loop variables or casts
- Comment out unused variables (keeping stream reads for side effects)
- Fix deprecated ManagedSurface operator= with copyFrom()
- Fix format string specifiers for int64 and missing type
- Fix sequence-point UB in FrameIndex increment
- Fix == that should be = in executingObjectIndex assignment
- Remove always-true >= 0 checks on uint16 values
- Add missing graphics/paletteman.h include
- Remove unused OPL status and mixerVolume variables

Commit Message:
MACS2: Validate all script opcodes against disassembly, fix bugs
Validated all 72 script opcodes (0x01-0x4E) against the original
MCSEXEC.EXE binary via Ghidra disassembly.
Bug fixes:
- Opcode 0x05 (comparison): Added missing sub-opcodes 0x04/0x05,
fixed inverted 0x02, fixed unsigned comparison in 0x03
- Opcode 0x06 (use-on): Fixed missing sub-opcode 2 inversion
- Opcode 0x10 (walk): Use pathfinding instead of ignoreObstacles lerp
- Opcode 0x20 (set Y offset): Also update runtime motion target
- Opcode 0x27 (set direction): Remove incorrect hardcoded hack
- Opcode 0x28 (stop animation): Also clear overload animation data
- PCM playback: Skip 2-byte header (original: size = stored - 2)
- Music fade: Add missing per-frame volume fade tick
Other improvements:
- Wall-sliding obstacle avoidance from walkAlongPath
- Background animation timing constants (mode 2: 39 ticks)
- 8-directional movement documentation
- Input state machine documentation
- Map/Save/Load panel system documentation
- MouseMode enum with all confirmed values
- Right-click opens action bar (not cursor cycling)
- Ghidra-matching comments on all opcode implementations

MACS2: Rewrite movement system, fix 5 remaining implementation gaps
Movement system rewrite (view1.cpp):
- Replace time-based lerp with pixel-by-pixel Bresenham stepping
matching walkAlongPath (1008:1b8f)
- Depth-scaled walk speed: speed = animSpeed * (word5201 + depth) / 100
- 8-directional orientation from delta comparison (not float angles)
- Per-pixel wall collision check with stop on hit
- Y-sort characters before rendering (back to front)
Pathfinding fix:
- LookupWalkability now uses GetPathfindingOverride for values 0xC8-0xEF
- Removed hardcoded test cases for 0xCB/0xCD
Save/Load:
- syncGame now saves object Orientation and Unknown fields
- Added script executor state (interacted objects, mouse mode)
Script fix:
- Separated scriptSkippable (102A) from global06BE (sound enabled)
- Opcodes 0x1C/0x1D now use dedicated bool instead of sound flag

MACS2: Fix timing (70Hz), cursor management, crash fix
- Fix frame rate from 20 to 70 Hz matching original DOS VGA vsync
(all timing was 3.5x too slow: fades, walks, animations)
- Fix crash in drawMainMenu: call openMainMenu(pos) instead of
setting isShowingMainMenu directly (uninitialized rect overflow)
- Cursor management:
- UpdateCursor handles Disabled mode (0x1A) by hiding mouse
- Hide cursor during frame waits (StartFrameWait)
- Restore cursor to Walk mode after all wait completions
- Right-click during script checks blocking conditions
- Map panel right-click guard: only opens if no dialogue/text/
overlay/sound wait is active

Commit Message:
MACS2: Rename all variables/functions to match Ghidra, fix timing bugs
Rename all generic globalXXXX variables to meaningful names:
- global06BE -> soundEnabled
- global06C0 -> musicEnabled
- global1032 -> isRepeatRun
- global103A -> pathWalkableResult
- global103C -> inventoryCheckResult
- global103E -> animBlobRangeTestResult
- global1040 -> inventoryActionFlag
- global1042 -> inventoryCombineFlag
- global1F4C -> mapPanelActive
Rename all FuncXXXX to match Ghidra function names:
- FuncA3D2 -> scriptSkipBlock
- FuncA37A -> scriptSkipAlternate
- Func9F4D -> scriptReadValuePair/scriptReadValue16/32
- FuncA334 -> scriptSaveVariable
- FuncC8E4 -> scriptStopAnimationImpl
- FuncC991 -> scriptLoadSpecialAnimImpl
- FuncB6BE -> scriptChangeAnimationWrapper/Impl
- Func101D -> getAreaAtPoint
- Func0E8C -> getWalkabilityAt
- Func1480 -> advanceAnimFrame
- Func168C -> getAnimFrameCount
- Adlib Func2792/27E4/2779/etc -> adlibWriteReg/SetInstrument/etc
Fix timing bugs:
- Remove incorrect cursor restoration on wait completions
(original just resumes script, cursor managed by script itself)
- Remove cursor hiding from StartFrameWait (done by opcode handler)
- Add IsSceneInitRun/isFrameWaitActive/isTimerActive check to
block right-click menu during intro
Other fixes:
- Action bar: proper 3x3 grid with centered icons
- Fade speed uses script transitionSpeed parameter
- Save/Load via ScummVM native dialog on right-click + action bar
- Text box click dismissal during script execution

Commit Message:
MACS2: Add game speed mode, input record/playback, and original save/load panel
- Implement Ctrl+T game speed cycling (0=normal, 1=fast, 2=slow) matching
the original binary's g_wGameSpeedMode at 1020:0214
- Add input record/playback system with console commands (record/playback/
stoprecord) using the original AHFFMCSR0100 file format
- Implement original save/load panel UI behind game option 'original_menus'
with 10 slots per page, 3 pages, and 7 buttons matching the original
handleMapPanelClick layout
- Wire up GAMEOPTION_ORIGINAL_SAVELOAD in metaengine and detection tables
- Rename g_wMapPanelActive to g_wSoundSystemActive to reflect actual semantics
- Fix opcode 0x38-0x3D hex format consistency in scriptexecutor.cpp

Commit Message:
MACS2: Fix game timing and music tempo, resolve stale TODOs
- Fix frame rate: game runs at ~20fps (PIT divisor 0xd7b0), not 70fps.
FRAME_DELAY changed from 1000/70 to 1000/20. This fixes frame waits,
walk speeds, music fades, and background animation timing.
- Fix music tempo: the original's PIT reprogramming and g2298 divider
always cancel to ~19.65 Hz effective music event rate. Override g2298
to CALLBACKS_PER_SECOND/20=6 to match at the fixed 120Hz OPL rate.
- Fix delaySeconds to use actual game frame rate instead of FRAME_RATE.
- Update bg animation timing constants (kGameFrameRate=20).
- Resolve 7 stale TODOs with confirmed information from Ghidra analysis:
opcode 0x28 purpose, IsRepeatRun semantics, executingScriptObjectID,
variable count (2048), timer race conditions, requestCallback status,
and adlib timer frequency explanation.

Author: Martin Gerhardy (martin.gerhardy at gmail.com)

Commit Message:
MACS2: Clean up dead code, fix script opcodes, improve correctness
- Remove dead test code: playTestSound(), PlaySound(), OnTimer()
- Remove hardcoded loadSongFromSceneData(7) test call for scene 6
- Remove commented-out test values in ScriptExecutor constructor
- Set ADGF_UNSTABLE flag in detection tables
- Fix opcode 0x25 (Sub values): implement as proper 32-bit subtraction
- Fix opcode 0x1E (Play animation): add validation matching original
- Fix opcode 0x0B (Move object): use actor index for inventory check,
store raw sceneID for parent attachment, terminate script on self-move
- Fix scriptSaveVariable: validate sub-opcode byte per original
- Fix IsRelevantObject: match original logic (check DataOffset, not scene)
- Fix getWalkabilityAt: handle 0xC8-0xEF override range instead of error()
- Fix console dumpBlobs: read path from args instead of hardcoded path
- Add scene resource cleanup in changeScene (free background animations)
- Rename IsRepeatRun to repeatRunFlag to disambiguate from isRepeatRun

MACS2: Fix hit-test ordering, inventory icons, scene cleanup
- Confirm hit-test ordering matches original (objects override background)
- Clean up inventory icon lookup: always uses blob slot 0x14 (validated
against drawInventoryPanel at 1008:532c), add bounds check
- Add scene resource cleanup: free background animation arrays on change
- Fix opcode 0x1E: add proper validation for objectID, slotID, blob data
- Fix getWalkabilityAt: handle pathfinding override range 0xC8-0xEF

MACS2: Remove dead code, fix build errors
- Remove dead legacy script functions (Func9F4DClean, Func9F4D, FuncA3D2,
ScriptReadWord, ScriptReadByte) superseded by ScriptExecutor class
- Remove dead BackgroundAnimation.FrameIndex tick code (blob system
handles frame advancement internally via GetCurrentFrame)
- Remove hardcoded test value (_backgroundAnimations[1].FrameIndex = 1)
- Remove broken Cmd_dumpOpl console command (underlying Adlib dump
functions no longer exist)
- Confirm depth test is correct against original (drawSpriteTransparent)

MACS2: Wire pathfinding into walk click, remove dead code
- Integrate existing pathfinding (FindPath/VisitPathfindingNode) into
normal walk click: use direct walk when line is walkable, fall back
to node network pathfinding otherwise (matches original handleInput)
- Remove dead legacy script functions (Func9F4DClean, Func9F4D, etc.)
- Remove dead BackgroundAnimation.FrameIndex tick code
- Remove hardcoded test value in script executor
- Remove broken Cmd_dumpOpl (underlying functions removed)

MACS2: Implement note-off, snap-to-walkable, remove dead code
- Adlib: implement note-off (0x80) channel release — find the channel
playing the note and call adlibSetupChannel to release it, mark as
releasing (validated against adlibISRHandler at 1000:2092)
- Implement snapToWalkablePosition (1008:9be2): scan for nearest
walkable pixel and apply gradient wall-push before pathfinding
- Wire snapToWalkablePosition into walk click handler
- Remove dead scriptChangeAnimationWrapper (never called)

MACS2: Fix inventory removal bug, remove hardcoded object skips
- Fix off-by-one in inventory item removal (foundIndex >= 0, not > 0)
- Remove hardcoded object index skip list in DrawCharacters — rely on
IsVisible flag set by opcode 0x33 instead of hardcoded exceptions
- Confirm inventory iteration order already matches original (by index)

MACS2: Implement Adlib percussion mode (channels >= 0xB)
- Extract and initialize gArray37/gArray57/gArray5C lookup tables from
binary data segment (validated addresses against Ghidra)
- Implement percussion note-on: load instrument registers (0x20, 0x40,
0x60, 0x80, 0xE0), calculate volume from gArray37, trigger via 0xBD
- Implement percussion note-off: clear bit in register 0xBD
- Bass drum (channel 0xB) uses frequency-only path
- Other percussion (0xC-0xF) uses full instrument register setup

MACS2: implemented help screen offset loading, fixed menu cursor and animation issues
* help screen is working now
* unified ui state with the original binary - this should fix a few issues where some
of the single bool values ran out of sync
* fixed fading for scenes
* connected the original save/load menu again (the ui is coming in a following commit)

previously we tried to open the ui in the same frame. this a) doesn't match the binary and b) produces problems
