"Activated" patch for ep4 v9 extra. Unpack to the game folder (where the exe is), overwriting any existing files.
Code:

Offsets for fb_unextra:
Ep3 v16: "316:30477"
Ep4 v9: "409:45509"
Below are some alternatives.
(*) If you want to just play and don't care about viewing images in an image viewer, put the corresponding z_activation_*.rpy file to the subfolder "game" inside the game folder. z_activation_316.rpy is for ep3 v16, and z_activation_409.rpy is for ep4 v9.
(*) If you want to decode images, use fb_unextra. It requires Java (oracle.com) and a functioning brain on the user side.
Run it without arguments to see usage help.
In short, you use it like this:
java fb_unextra -if INFOLDER -of OUTFOLDER -o OFFSET
INFOLDER
is the game folder.
OUTFOLDER
is the folder to put the decoded images to.
OFFSET
depends on the game version. For ep3 v16 it's "316:30477". For ep4 v9 it's "409:45509".
For Windows users, there are "fb_unextra.drop.*.bat" scripts for convenience - just drag and drop the game folder on it and it should decode the images for you, backing up the original files as "*.(z117extra).jpg".
