Purpose of this PR:

Fix of #389

Summary by CodeRabbit

  • New Features

    • Recomp configuration now synchronizes Dolphin user, Load, NAND, and Retro Rewind paths.
    • Redirected or newly created NAND locations are supported.
    • Recomp paths are reapplied after installation, updates, launches, and app-data relocation.
    • Added a setting for the Retro Rewind runtime path.
  • Bug Fixes

    • Prevented stale shared NAND and pack paths from remaining in configuration.
    • Improved configuration updates after app-data moves and backend configuration recreation.

📝 Walkthrough

Walkthrough

The recomp path service now updates NAND and Retro Rewind paths. Launch, install, update, NAND settings, and appdata relocation invoke the renamed method. New tests cover path resolution, relocation, cleanup, idempotency, and configuration timing.

Changes

Recomp path synchronization

Layer / File(s) Summary
Path contract and service implementation
WheelWizard/Features/Settings/ISettingsServices.cs, WheelWizard/Features/Settings/SettingsManager.cs, WheelWizard/Features/Recomp/RecompDolphinDataService.cs
Adds RECOMP_RETRO_REWIND_ROOT. Renames the path application method. The service writes Retro Rewind and NAND paths and accepts redirected user folders.
Path resolution and persistence tests
WheelWizard.Test/Features/Recomp/RecompDolphinDataServiceTests.cs
Adds tests for overrides, sharing and copying, stale configuration cleanup, relocation, idempotency, and configuration creation timing.
Launcher path application
WheelWizard/Features/Recomp/RecompLauncher.cs
Applies all runtime paths after reconciliation, installation, and update operations.
Settings-driven path application
WheelWizard/Views/Pages/Settings/RecompSettings.axaml.cs, WheelWizard/Views/Pages/Settings/WhWzSettings.axaml.cs
Applies paths after NAND changes and appdata relocation. Reports synchronization failures in the move warning message.

Merge Risk: 🟡 Moderate · up to 02e15

Path synchronization can silently leave stale runtime paths and allow affected operations to continue, so persistence failures should be surfaced before merge.

Return failure when Config.toml cannot be read.

When an existing Config.toml cannot be read, ReadTomlFile returns null, and WriteTomlSetting skips the write. The Action<RecompSetting> callback makes RecompSetting.SetInternal return validation success only. ApplyPathsToRecompConfig can therefore report success, allowing launch, install, or update to continue with stale paths.

Distinguish a missing file from a read failure. Keep the missing-file case as the intentional successful no-op before installation. Return the save result from RecompSettingManager, propagate it through RecompSetting.SetInternal, and make Setting.Set report the failed persistence.
