MINI-TWEAKER INSTRUCTIONS:
As usual, back up any file you plan to change before doing this (Although the Mini Tweaker will create a backup for you anyway).

1. Download and install Mini-Tweaker by:
1A. Download nvdrifter's collection of modding tools as modtools.rar from here:
http://www.savefile.com/files/684634 or at this website here and unzip modtools.rar,
then unzip SH4_Modding_Tools_and_Utie.zip

1B. Unzip SH3MiniTweaker_build104.zip
1C. Run setup.exe
NOTE: The default installation folder is \SH3 Mini Tweaker, but you can install it wherever you want. We will assume you leave it as \SH3 Mini Tweaker.
1D. Create a subfolder under the \Sh3 Mini Tweaker folder called \SH4Tweakfiles.
1E. (OPTIONAL) If you are going to be using Mini Tweaker on an SH3 installation as well as an SH4 installation, create another subfolder under the \SH3 Mini Tweaker folder called \SH3Tweakfiles.

2. Install the SH4 Tweak files by:
(NOTE: These Step 2 instructions are a little complicated because not all of the zipped tweak files use the same directory structure. But its easier to sort them out now, rather than deal with the additional time it takes to change directories, every time you run Mini-Tweaker and load a tweak file later).
2A. Unzip "SH4 Aircraft .zon and .sim Tweak Files.zip" to a temporary directory (we'll assume you call it \SH4temp).
Copy all of the files in the \SH4temp\SH4 Aircraft .zon and .sim Tweak files folder to the \SH3 Mini Tweaker\SH4Tweakfiles folder.
2B. Unzip "SH4 Sub .sim and .zon Tweak files.zip" to \SH4temp.
Copy all of the files in the \SH4temp\SH4 Sub .sim and .zon Tweak files folder to the \SH3 Mini Tweaker\SH4Tweakfiles folder.
2C. Unzip "AI Sensors.dat Tweak File.zip" to \SH4temp.
Copy all of the files in the \SH4temp\AI Sensors.dat Tweak File folder to the \SH3 Mini Tweaker\SH4Tweakfiles folder.
2D. Unzip "scene.dat_Tweak_File.zip" to \SH4temp.
Copy all of the files in the \SH4temp\scene.dat Tweak File folder to the \SH3 Mini Tweaker\SH4Tweakfiles folder.
2E. Unzip "SH4_Ship.sim_Tweak_Files.zip" to \SH4temp.
Copy all of the files in the \SH4temp\SH4 Ship.sim Tweak files\SH4 Ship.sim Tweak files folder (Yes there are two identically named folders) to the \SH3 Mini Tweaker\SH4Tweakfiles folder.
2F. Unzip "Sub Gun .sim Tweak Files.zip" to \SH4temp.
Copy all of the files in the \SH4temp\Sub Gun .sim Tweak Files\Sub Gun .sim Tweak Files folder (Yes, again there are two identically named folders) to the \SH3 Mini Tweaker\SH4Tweakfiles folder.
2G. (OPTIONAL) If you are going to be using Mini-Tweaker on an SH3 installation as well as an SH4 installation, download the SH3 tweak files (in a file called tweakfiles.zip) from:
http://www.delraydepot.com/tt/sh3sdk.htm#tweaker
Then unzip tweakfiles.zip into the \SH3 Mini Tweaker\SH3Tweakfiles folder.


3. Run Sh3 Mini Tweaker
NOTE: If you do not have SH3 installed on your system you will get a pop-up saying, "Unable to find SH3 registry key. Manually choose this or another game folder path". Just ignore it and click OK.

4. Pick the SH4 installation you want to make changes in by:
4A. In the upper right corner of the screen where it says, "Locate alternate game folder", click the "..." button. Browse to the \Silent Hunter Wolves of the Pacific folder of the installation you want to make changes in and select it.
NOTE FOR SH3: If making changes to an SH3 installation, you would instead browse to the \SilentHunterIII folder of the installation you want to make changes in and select it.

5. Pick the file you want to change by:
5A. Click on the "Load Tweak File" button at the top middle of the screen. This brings up the "Select Tweak file" screen. Browse to your \SH3 Mini Tweaker\SH4Tweakfiles folder.
NOTE FOR SH3: If making changes to an SH3 installation, browse to your \SH3 Mini Tweaker\SH3Tweakfiles folder instead. The rest of the instructions below apply equally whether you are editing an SH3 or SH4 installation. Just susbstitute SH3 for SH4 in the descriptions.

5B. All of the SH4 files are shown here in one directory. You don't have to browse down through subdirectories. Just choose the one you want.
TECHNICAL NOTE: You will note that the files all have a .txt extension tacked onto them. This is because technically these are the "tweak" files (files used to map Mini Tweaker to the real files), but pick them just as if they were the real files.
SECOND NOTE: Many, but not all, SH4 files are listed here. To change a file not listed here you would have to create your own tweak file, which is a whole other subject.

6. Pick the Category and field you wish to change within the file by:
6A. From the drop down list at the upper left, pick a category. These change from file to file.
EXAMPLE: If you were changing the Deck_Gun_3_50.sim file, the categories shown are "Shell storage amounts", "shell specs" and "gun barrel movement and recoil". To edit the reload time pick "shell specs" from the menu.
6B. The "Names and Values" box will now show a list of all of the fields within that category you can change. Click on the one you want.
EXAMPLE: Under "shell specs" you will see seven fields, Shell Speed, Clip Size, Reload Time, Maximum Range, Angle, Travel tolerance, Elevation Tolerance. Click on the Reload Time field (This field influences, obviously, the amount of time to reload).
6C. Enter the new value you want for that field in the "New Value" box on the middle right of the screen. Click on the "Save new value" box.
EXAMPLE: Enter 6 into the box and click "Save new value" (This would increase the reload time).
6D. Exit Mini Tweaker

7. The Mini Tweaker created a backup copy of the file you just changed, in the same directory as the original file. The name is the usual "Copy of ...." name. You should move this to some other directory (otherwise the game sometimes gets confused and still uses this copy with the old values in it).

You're done. Test your change.

NOTE: Various modders periodically issue additional tweak files. Use the search function to find them.

Just follow the same procedure you did in Step2 above, to unpack and use them. Make sure that the ".txt" files go directly into the \SH3 Mini Tweaker\SH4Tweakfiles folder, or each time you click "Load tweak file" you'll have to change the directory to wherever you put them.

Here is a link to a thread for the shells.zon file:
http://www.subsim.com/radioroom/showthread.php?t=111831&highlight=shells.zon+tweak

There is currently no link for the additional Torpedoes_US.zon file, so I have put the contents into the thread listed below, so you can cut and paste the contents into your own text file.
