Divine Pulse v1.2.9 - First Public Release

The first public release of Divine Pulse: a free, open-source Windows app for tracking your Fire Emblem: Three Houses army and replaying your battles while you play in Eden. Your runs, battles and imported game files stay on your PC.

The version number continues from private development. Versions through 1.2.8 were unpublished development builds.

What you can do

• Follow your army automatically. Read every unit's stats, class and abilities from game memory, compare effective base stat totals (eBST), and keep a separate run for each playthrough.
• Follow battles live. See the turn, timer, unit HP, map and action log, alongside estimated battle outcomes.
• Replay what happened. Step through recorded battles on the map and review unit statistics, records and graphs.
• Keep the actions Divine Pulse undid. Rewound actions remain available as alternate timelines, with a tree view for exploring their branches.
• Review your playthrough. History brings together your battles, run totals and character statistics.
• Browse an offline reference. Characters, Archive and Supports use data imported from your own game, with language selection and spoiler controls.

The app opens in its own desktop window and can keep tracking from the system tray. It only reads emulator memory; it never changes the game.

Download and start

Choose one of the files below:

Download	Use it for
Divine-Pulse-1.2.9-setup.exe	Recommended. Install for your Windows user, add shortcuts, and import game files during setup. No administrator prompt is required.
Divine-Pulse-1.2.9-windows-portable.zip	Extract the entire archive to a folder, run Divine Pulse.exe, and import game files on the first screen. Keep the executable, its .config file and the _internal folder together.
SHA256SUMS.txt	Verify the downloaded installer or ZIP against its SHA-256 checksum.

Python and Node.js are not required. The app is unsigned, so Windows SmartScreen may show a warning on first launch. After verifying that you downloaded it from this repository, choose More info → Run anyway to continue.

Requirements

• Windows 10 or 11, 64-bit, with Microsoft Edge WebView2. Windows 11 includes WebView2; without it, the app falls back to a browser.
• Fire Emblem: Three Houses with update 1.2.0, running in Eden with fastmem enabled. Eden is the tested emulator; other game versions and Ryujinx are not supported.
• Your own game files: an extracted dump including ExeFS, or your base game, update and optional DLC NSPs with your own prod.keys. See the game-file preparation guide.

Divine Pulse ships no game art, text or tables, and includes neither the game nor an emulator. Import your own files once to populate the app. NSP extraction uses the bundled tool, so it needs no separate tool download.

Desktop startup reliability

This release fixes a problem found while testing the unpublished 1.2.8 download: Windows could mark extracted DLLs as Internet files and prevent the standalone window from loading. The portable package now includes the application-specific configuration needed to load those DLLs. The release build also opens a real WebView2 window with those download markers present, so this failure stops packaging instead of reaching a release.

Development and privacy

This is the first public release from a solo maintainer, and rough edges remain. Battle outcome and inferred-fight figures are estimates. Bug reports about tracking accuracy and game-file imports are especially useful.

There is no account, telemetry or automatic update check. The local server listens only on 127.0.0.1 and rejects requests from other websites. Watch the releases page for updates.
