2. Press F2 key, and copy'n'paste the following bytes: E3 6A 7E 44 1E 92 97 51 6E 6E 5D BA
3. Drag'n'drop your .bfz file onto the window
4. Click on the "Decrypt / Unpack all" button
5. If you have more .bfz files, go to step 3.
Note: if you don't know the key then skip step 2, GAME RIPPER can crack ZIP encryption if there's at least one uncompressed PNG, WEBP, WAV or OGG in the archive (which is the case with your hyymbp.bfz file, the others seem to have .msh files only). This uses the Biham and Kocher attack running simultaneously on all CPU cores, so takes only a few minutes on a typical PC.
holy crap, wasn't expecting a reply this fast. The only gripe I have is that there doesn't seem to be an option to specify where the extracted files should be dumped, but otherwise your tool works wonders.
only question I have is, does the above key only work for the hyymbp.bfz file? I tried dragging other .bfz files such as this one (og filename: ActionMessage) to the program and nothing loads, yet when I try dragging the file to the program first without entering the encryption key above it starts the key decryption process...but it takes awfully long since I'm using a low-spec laptop with a weak CPU. maybe someone with a better computer could try using the program.
edit: this is probably a dumb question but how can you tell if the archive contains an uncompressed PNG/WEBP/WAV/OGG/etc file in it? is it just a matter of guessing?
