From d1e9a5e0d53eb98fbb62a6bf0a9b112eb1bb5bf7 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Sun, 14 Dec 2025 20:00:36 +0000 Subject: [PATCH 21/27] WIP: Switch to DS-relative addressing with MemoryBasedDataStructureWithDsBaseAddress This is a work-in-progress commit that changes the architecture to use DS-relative offsets as requested. The model now extends MemoryBasedDataStructureWithDsBaseAddress and uses DS-relative offsets throughout. Changes: - DuneGameState now extends MemoryBasedDataStructureWithDsBaseAddress - All offsets are DS-relative (e.g., DS:0x0029 for charisma) - Split into partial classes (Locations, Troops, NPCs, Smugglers) - GameEngineWindowManager and ViewModel updated to pass SegmentRegisters Note: ViewModel needs updates to call methods instead of properties. The approach is correct but implementation needs completion.

Per GlobalsOnDs.cs and user feedback, the main Dune code uses DS=0x1138 which translates to linear address 0x11380 (segment * 16). Using fixed address ensures stability even if DS register changes during execution. Changes: - DuneGameState: Switch base class, remove SegmentRegisters from constructor - DuneGameStateViewModel: Remove SegmentRegisters parameter - GameEngineWindowManager: Remove SegmentRegisters parameter - Overrides: Remove SegmentRegisters from ShowWindow call - Fix charisma formula: raw value directly (0 = 0, not 0 = 1) Co-authored-by: maximilien-noal <1087524+maximilien-noal@users.noreply.github.com> --- .../GameEngineWindowManager.cs | 5 +- .../GameEngineWindow/Models/DuneGameState.cs | 55 ++++++++++--------- .../ViewModels/DuneGameStateViewModel.cs | 5 +- src/Cryogenic/Overrides/Overrides.cs | 2 +- 4 files changed, 33 insertions(+), 34 deletions(-) diff --git a/src/Cryogenic/GameEngineWindow/GameEngineWindowManager.cs b/src/Cryogenic/GameEngineWindow/GameEngineWindowManager.cs index b030977..3091742 100644 --- a/src/Cryogenic/GameEngineWindow/GameEngineWindowManager.cs +++ b/src/Cryogenic/GameEngineWindow/GameEngineWindowManager.cs @@ -7,7 +7,6 @@ namespace Cryogenic.GameEngineWindow; using Cryogenic.GameEngineWindow.ViewModels; using Cryogenic.GameEngineWindow.Views; -using Spice86.Core.Emulator.CPU.Registers; using Spice86.Core.Emulator.Memory.ReaderWriter; using Spice86.Core.Emulator.VM; @@ -16,7 +15,7 @@ public static class GameEngineWindowManager { private static DuneGameStateViewModel? _viewModel; private static bool _isWindowOpen; - public static void ShowWindow(IByteReaderWriter memory, SegmentRegisters segmentRegisters, IPauseHandler? pauseHandler = null) { + public static void ShowWindow(IByteReaderWriter memory, IPauseHandler? pauseHandler = null) { Dispatcher.UIThread.Post(() => { // Check window state first using the flag which is the source of truth if (_isWindowOpen) { @@ -27,7 +26,7 @@ public static void ShowWindow(IByteReaderWriter memory, SegmentRegisters segment // Clean up any existing viewmodel _viewModel?.Dispose(); - _viewModel = new DuneGameStateViewModel(memory, segmentRegisters, pauseHandler); + _viewModel = new DuneGameStateViewModel(memory, pauseHandler); _window = new DuneGameStateWindow { DataContext = _viewModel }; diff --git a/src/Cryogenic/GameEngineWindow/Models/DuneGameState.cs b/src/Cryogenic/GameEngineWindow/Models/DuneGameState.cs index 4469f6b..029b5da 100644 --- a/src/Cryogenic/GameEngineWindow/Models/DuneGameState.cs +++ b/src/Cryogenic/GameEngineWindow/Models/DuneGameState.cs @@ -1,47 +1,49 @@ namespace Cryogenic.GameEngineWindow.Models; -using Spice86.Core.Emulator.CPU.Registers; using Spice86.Core.Emulator.Memory.ReaderWriter; using Spice86.Core.Emulator.ReverseEngineer.DataStructure; /// -/// Provides access to Dune game state values stored in emulated memory using DS-relative offsets. +/// Provides access to Dune game state values stored in emulated memory at fixed DS segment address. /// /// /// -/// This partial class uses MemoryBasedDataStructureWithDsBaseAddress which automatically -/// resolves DS-relative offsets at runtime.
