Version Notes

Introduce external JSON configuration

This refactor fundamentally changes how the mod is configured by moving all backpack size data from a hardcoded dictionary into an external config/config.json file.

Allows users to easily customize backpack sizes without recompiling the mod.
The mod now reads all settings from the JSON file on server startup.
Added a non-functional 'ItemName' field to the config for better readability and user experience.
Bumps the mod version to 2.0.0 to reflect this significant breaking change.

Jero’s Backpack Rework

Inspired by Josh Mate’s Better Backpacks mod.

Tired of playing inventory Tetris? This mod reworks backpack sizes to be more logical and less of a headache. Big raid packs now actually have space for your loot, and smaller bags are more balanced. Get in, get out, and spend less time messing with your inventory.

Backpack Size Changes

The table below details all the changes made.

Old HxV > New HxV
6x8 6x11
6x7 6x10
5x7 5x10
5x6 5x8
3x8 4x9
5x5 5x7
5x4 5x6
4x5 5x6
4x4 4x6
2x7 3x7
4x3 4x4
3x4 4x4
3x3 4x3
4x2 4x3
3x2 3x3

You are able to alter the backpack sizes within the config.json file, located in the /config directory. Please ensure the server is shut down before performing this action.

I do not assume responsibility for any issues that may arise with your profile. It is advised that you create a backup before making any modifications.

Installation

  1. Make sure your server is not running.
  2. Unzip the downloaded file.
  3. Place the jerobackpack folder into your user/mods/ directory.
  4. Start your server. The new backpack sizes will be applied.

Compatibility

This mod directly edits the properties of vanilla items. It will conflict with any other mod that also alters the stats of these same backpacks. It should be compatible with everything else.

Enjoy the extra space!

Rework on backpack sizes

Zip contents folder is wrong. It expands to mod folder, instead of bepinex folder.

Hi, the structure is correct, this mod should not go to the bepinex folder, this mod is in the SPT/user/mods/… folder

Regular mods (non BepinEx) are also DLLs now, in case that’s why you thought it should go in a different folder.

The maths on the description is absolutely butchered.

Old HxV > New HxV > Increase %

6x8 6x11 37.50% -> 37.3% (Within margin of rounding, so a pass)

6x7 6x10 42.86% -> 30%

5x7 5x10 42.86% -> 30%

5x6 5x8 33.33% -> 25%

3x8 4x9 50.00% -> 33.33%

5x5 5x7 40.00% -> 28.58%

5x4 5x6 50.00% -> 33.33%

4x5 5x6 50.00% -> 33.33%

4x4 4x6 50.00% -> 33.33%

2x7 3x7 50.00% -> 33.33%

4x3 4x4 33.33% -> 25%

3x4 4x4 33.33% -> 25%

3x3 4x3 33.33% -> 25%

4x2 4x3 50.00% -> 33.33%

3x2 3x3 50.00% -> 33.33%

Literally unplayable. Pls fix. /s

Yes, you should be able to change the source code on GitHub and compile a new .dll file

Maybe a config file for the future if you can?

Hey, that’s a false positive. Feel free to check the VirusTotal report linked on the mod page. If you don’t feel safe, no worries, just don’t use it. You can also check out the source code on GitHub

Windows Defender often marks most mods as viruses; just disable windows defender before you install this mod, or really any mod.

This is the same answer used on the official SPT Discord community; I just copied and pasted it for my own convenience. If you don’t feel safe using it, then please don’t. I have no problem with that at all. I originally made this mod for my own personal use and just decided to share it in case anyone else was interested.

*I’m using a translator as English isn’t my native language, which is why this might sound a bit formal.

I have confirmed that the (current version of the) mod is not malicious in any way

You can read through the source code if you don’t trust it. It’s on github: https://github.com/silviohmartins/JeroBackpack I went through it, and nothing about it seems malicious

unzipped content is just a dll file, no folder, is it right?

Create a subfolder named jerobackpack and put the dll inside it, the server will load it then. Have not tested it myself.

Defender flags this download as a virus.

0 Likes

Virus Detections. Many new and unrecognised files may flag as a virus on anti-virus programs. This is particularly prominent on mods that contain an Executable .exe (e.g. Realism, SVM) or a Dynamic Link Library file .dll as these files are the most common ways for a bad actor to infect a system. If an anti-virus scans a file and it detects something that does not seem right, it will flag as a virus even if it is completely safe. This is called a false-positive. You can read up on false-positives here > https://csrc.nist.gov/glossary/term/false_positive.

Mods are required to have a VirusTotal link on the modpage. You can click this link to see it’s detections, or do the scan yourself. You should do your OWN research when it comes to your online security and to not base your decision on others.

If YOU don’t trust it then don’t use it.
