Introduces a new HomebrewEmulator class implementing the IEmulator interface. This stub provides method signatures for loading binaries, running, stepping, decompiling, and recompiling firmware, with NotImplementedExceptions for unimplemented functionality.
Refactored MainWindow.xaml.cs to modularize and expand emulation handlers for various platforms, including Dish Network/VxWorks, Uverse, RDK-V, RDK-B, SWM Switch/LNB, and CMTS. Added new menu options, improved file dialogs and status updates, and implemented or stubbed out feature-specific logic for each emulation type. Removed duplicate and stub methods, and improved UI feedback for analysis and simulation tasks.

Pull Request Overview

This PR sets up build and debug configurations, refactors emulator classes to use modern C# patterns, and extends the main UI (MainWindow) to support additional emulation workflows.

  • Adds root and Emulation/ tasks.json and launch.json for build and debug tasks
  • Refactors switch statements to expression switches and uses collection initializers
  • Extends MainWindow.xaml.cs with new interfaces, handlers, and helper methods

  • Changing StartMediaroom from an instance to a static method may break existing usage patterns. Confirm callers and consider keeping it as instance method if state is required.

  • The tasks.json args array is incomplete and ends with an unterminated string literal. Please finish the argument value, close the array, and ensure the JSON is valid.

Added memory and register initialization, a fetch-decode-execute loop for MIPS32, and support for several core instructions (ADD, SUB, ADDI, LW, SW, BEQ, BNE, J). Also added a simple disassembly output in Decompile(). ARM and other architectures are stubbed for future implementation.
Eliminated redundant implementations of HandleCmtsEmulation, HandleRdkBEmulation, HandleRdkVEmulation, and HandleFilesystemProbe. This cleanup reduces code duplication and improves maintainability.
Bumped the AssemblyInformationalVersion attribute to reflect a new build or commit hash.
Enhanced the Detect method to identify Broadcom BCM7346 firmware by checking for the 'BCM7346' marker in the initial region of the binary or image. This helps in recognizing MIPS32-BCM7346 targets more accurately.
The HomebrewEmulator now scans loaded firmware for a Flattened Device Tree (FDT) blob by checking for the 0xd00dfeed magic number. If found, it loads the device tree using DeviceTreeManager, enabling future support for hardware description parsing.
Introduces DeviceTreeManager with basic structure for parsing Flattened Device Tree (DTB) files, including node representation and stubs for loading and searching compatible nodes. Actual DTB parsing logic is yet to be implemented.

This pull request introduces several enhancements and fixes across multiple files, primarily focusing on emulator development, code refactoring, and debugging configuration. Key changes include the addition of new emulator classes, refactoring of existing methods for improved code clarity, and the introduction of debugging and build configuration files.

Emulator Development:

  • Added a new HomebrewEmulator class in Emulation/HomebrewEmulator.cs to provide a stub for native firmware execution, with fallback to QEMU for unsupported features. This includes basic MIPS instruction handling and device tree detection.
  • Introduced stub implementations for multiple architectures (e.g., Sparc64, Alpha, RiscV, SuperH, etc.) in Emulation/StubEmulators.cs, providing basic method definitions for loading binaries, running, stepping, and recompiling.
  • Added a minimal SparcEmulator class in Emulation/SparcEmulator.cs as a placeholder for future implementations.

Code Refactoring:

  • Simplified object initialization syntax by replacing explicit constructors with shorthand initializers in DvrVxWorksDetector.cs and Emulation.cs. [1] [2]
  • Refactored several methods in DvrVxWorksDetector.cs to use static declarations where appropriate, improving encapsulation and reducing potential side effects. [1] [2] [3]

Debugging and Build Configuration:

  • Added a launch.json file in Emulation/launch.json to enable debugging configurations for the processor emulator, allowing users to specify executable names dynamically.
  • Added a tasks.json file in Emulation/tasks.json to define build tasks using dotnet, streamlining the development workflow.

Other Fixes:

  • Updated EmulatorLauncher.cs to replace direct qemu calls with QemuManager for better abstraction and modularity.
