Usage

1. Drop Profile.save onto the page (Steam path below)
2. Hit Decrypt. Set Medallions, Premiums, Farmers, or Battle Score; or edit any field in the tree / raw JSON
3. Use Known from game data under the editor to browse catalogs from the client extract and Add/Remove them on the save
4. Sanitize zeros DetectedHacks, deletes StreamID, and sets DateTime / Timestamp to now
5. Encrypt & Download (Sanitize is pre-checked). Replace the file in the Steam folder

Steam path:

Steam\userdata\[steamid]\444640\local\Data\Docs\64878ecb93c456c059ea530d

Android path:

/data/data/com.ninjakiwi.bloonstdbattles/files/64878ecb93c456c059ea530d/

Close the game before replacing the file. Keep a backup of the original Profile.save.

Catalogs

catalogs.json ships with the site. It is generated from a local Assets/ unpack of the game’s data.jet (premiums, towers, skins, etc. for the reference panel).

npm run extract-catalogs

Assets/ and Assets.zip are gitignored; only the derived catalogs are committed.

Unpacking Android data.jet

For regenerating catalogs from an Android client build (APK unpack). Steam packaging is different; this script expects Android libnative.so (arm64-v8a) and that build’s data.jet.

data.jet is a ZipCrypto ZIP. The pack password is not a fixed string — each client build embeds a password seed in libnative.so. The extract script turns that seed into the pack password, verifies it with unzip -t, and writes Assets/ for the catalog step above.

npm run extract-data-jet -- \
  --so /path/to/lib/arm64-v8a/libnative.so \
  --jet /path/to/assets/Assets/data.jet
npm run extract-catalogs

Use the same Android build for both files. --password-only prints the pack password and skips writing Assets/. Passwords are not checked into this repo.
