Integrate Emulator-Native Playtime Into LaunchBox

📋 Summary

Use playtime reported by emulators (and storefronts) as the primary source of truth for each game, instead of relying only on “time-in-focus” tracking. This improves accuracy when games are launched outside LaunchBox or when focus changes mid-session.

🎯 Feature Overview

• Detect and read emulator-native playtime where available, then write/merge it into LaunchBox’s playtime field.

• Support periodic sync (on game exit, on LaunchBox start, or manual “Sync Playtime” action).

• Provide per-emulator toggles: Use emulator playtime, Prefer LaunchBox timer, or Merge.

• Expose a conflict rule (e.g., “take max,” “sum,” or “prefer emulator”).

• Log changes in the game’s audit/history so users can see when and why a number changed.

Combine with Manual Playtime Editing to fill gaps

🧩 Example Integrations (initial targets)

• Dolphin (Wii/GC): read per-title stats files.

• RPCS3 (PS3): read game time from games.yml/config DB.

• Vita3K (PS Vita): read per-title playtime store.

• RetroArch: optionally read core/game runtime where available (in addition to LaunchBox’s existing timing).

• (Stretch) PCSX2, PPSSPP, Cemu, Yuzu/Ryujinx if/when stable per-title counters exist.

🔁 Sync & Conflict Handling

• Modes:

  • One-way (Emulator → LaunchBox): overwrite LaunchBox playtime with emulator value.

  • Merge: add delta since last sync (avoids double-counting).

  • Prefer Greater: choose the larger of the two values.

• When: on game exit, on app launch, scheduled, or manual per-platform.

• Where stored: per-game “Last Sync Source / Timestamp” to prevent duplicate adds.

📦 Benefits

• More accurate playtime when games are launched outside LaunchBox or when focus is lost.

• Consistent stats across multi-device setups (desktop/handheld) that use different launch paths.

• Less manual correction; better inputs for playlists, progress automation, and analytics.

📱 Android & Cross-Build Considerations

• Add a lightweight provider layer on Android to read emulator stats where possible; fall back to LaunchBox timing if not available.

• Respect existing cloud sync: merged values should sync just like current playtime/play count.
