DMG Extension

A browser extension for Granblue Fantasy and this site. Leave Capture on while you play: each battle's log is kept for the Verifier, and Import puts your team into your account here.

Use at your own risk; it only reads what the game sends.

To check the downloaded file, run this in PowerShell in its folder and compare:

Get-FileHash .\dmg-extension-1.6.0.zip

What it does

  • One Capture toggle in its popup, which you leave on while you play.
  • Copy each battle for the Verifier; saving to Downloads is a setting (off in this build).
  • The last 10 battles stay in the extension, listed in the popup.
  • Import puts the captured team into your account here, as a private team.

A battle into the Verifier

  1. Before the battle, open the popup on the game's tab and turn Capture on.
  2. After the battle, open the popup and click Copy on that battle's row.
  3. Open the team here, then Simulator, Verify, and Paste.

The Verifier takes up to 512 KB of log; the popup says when a battle is longer.

Install

Chrome, Edge, Iron, Brave or Opera on a computer. Firefox, Safari and phones are not supported.

  1. Download the zip above.
  2. Open your browser's extensions page: copy its address into the address bar (a web page cannot link to it).
    • Chrome chrome://extensions
    • Edge edge://extensions
    • Iron chrome://extensions
    • Brave brave://extensions
    • Opera opera://extensions
  3. Turn on Developer mode.
  4. Drag the zip onto the extensions page.
  5. Check that its ID reads pjlkkidligocdbehafaojgdklnjjocog.
  6. Pin it to the toolbar from the extensions (puzzle piece) menu.
  7. Sign in on this site in the same browser: Import uses that sign-in.

If dragging the zip does not work: extract it (Extract All makes a folder named dmg-extension-1.6.0 with manifest.json directly inside), click Load unpacked and pick that folder.

Update

When a newer version is out, the popup shows Update with its number and opens this page.

Download the new zip and drag it onto the extensions page the same way.

Installed from a folder instead: replace the files inside it with the new zip's, then click the reload arrow on the extension's card.

Never click Remove: that deletes its stored data (kept battles, learned status names).

What you will see

While Capture is on, the browser shows a bar saying the extension started debugging this browser. That is how it reads the game's responses; Stop, or closing the game tab, ends it.

The extension's details page lists its permissions in the browser's words:

  • Access the page debugger backend
  • Read and change all your data on all websites
  • Manage your downloads

The first two are the debugger permission. The extension attaches it to the game's tab only, only while Capture is on, and only reads.

Some browsers remind you at start-up that a Developer-mode extension is installed.

Privacy

  • It reads game responses only while Capture is on, and only on the game's tab. Nothing runs inside the game page.
  • Battle logs stay in the extension on your computer; they reach Downloads only when you click Save or turn that setting on.
  • Import sends the team (party, character pages, EMP, rings, class EMP; user and viewer ids removed, 500 KB at most) to this site as you. Imported teams are private.
  • Nothing else is sent: no analytics.
