What this mod does:
This mod uses xdelta to inject a patch into the "volume.dat" file in your game installation to restore old dialogue from before the 2023 patch

Step 0
Backing up the volume.dat file.
First of all, navigate to your game directory (...\Steam\steamapps\common\Akiba's Trip Undead & Undressed) and create a backup of "volume.dat"

You can do this by either creating a new folder and copying it there, or simply renaming it "bakvolume.dat" or whatever your preference is

Step 1
Download the .zip archive from Google Drive[drive.google.com]

Step 2
Extract the .zip archive (location does not particularly matter). You should see the following files within the "AdmiralAckbarMod" folder
Step 3
In the AdmiralAckbarMod folder, open "xdeltaUI"
Under the (default) Apply Patch tab you will see 3 fields:

• Patch - where we will be selecting the patch to replace the dialogue
  
• Source File - where we will be selecting the original "volume.dat" file
  
• Output File - the name/location of newly generated "volume.dat" file with the patch applied

Step 4a
Click on "Open" beside "Patch" and navigate to the folder you just extracted
Open the "AdmiralAckbarPatch" folder and double (left) click the AdmiralAckbarPatch.xdelta file to open it

Step 4b
Then, repeat this process for "Source File".
Navigate to your game directory (...\Steam\steamapps\common\Akiba's Trip Undead & Undressed) and double (left) click the "volume.dat" file to open it (in this case bak_volume.dat, as I renamed the file as detailed in Step 0, as a backup)

Step 4c
Finally, we're going to select an output directory for the patched file.
(left) click the [...] button under "Output File"
Navigate to your root game directory (C:\Program Files (x86)\Steam\steamapps\common\Akiba's Trip Undead & Undressed) and make sure the name is "volume.dat" for the output file

Step 5

Now you can select "Patch" and within a few moments the game should be patched and your traps will be restored

Step 6
After this your game directory should look something like this:

Feel free to remove the backup file you made at the start (to clear up some diskspace). This is, of course, optional.
