Battleborn Info Dumps

Sadly I “got into” digging into this game a bit too late for me to do the best type of digging for live service games… :/
But I’ve got some assorted info (and TODO: asset dumps)

Initialization

When you launch up the game, it’s gonna ask Gearbox’s servers for their SparkTMS package.

• Borderlands 2+TPS(and 3) also have this system, unsure on the format for BL3

It requests the SparkTMS package from: http://cdn.services.gearboxsoftware.com/sparktms/poplar/pc/steam/BattlebornTMS-prod.cfg
Gearbox continues to follow the pattern of naming their games/projects after plants/trees

• Trees are usually games and plants/”lower” trees are usually DLC or less important projects

But either way, for Battleborn, it follows the same setup and format as Borderlands 2.
Rather than implement it myself, I just used Gibbed’s SparkTMSUnpack program over on Github.
For fun (and cause why not), I made a dead simple Python script to quickly re-unpack the TMS file from a python script to avoid having to continue to redownload it if you want to check in on it for some reason

import requests
import os
import subprocess
import shutil

url = "http://cdn.services.gearboxsoftware.com/sparktms/poplar/pc/steam/BattlebornTMS-prod.cfg"
savedFile = url.split("/")[-1]


if os.path.exists(savedFile):
    print(f"Deleting old {savedFile} and dir...")
    os.remove(savedFile)

print(f"Requesting new {savedFile}")

with requests.get(url) as r:
    r.raise_for_status()
    with open(savedFile, "wb") as f:
        f.write(r.content)

execName = f'./Executables/Gibbed.Borderlands2.SparkTmsUnpack.exe "{savedFile}" -o'
subprocess.run(execName)


# Create a zip file
shutil.make_archive(f"./{savedFile[:-4]}", "zip", f"./{savedFile[:-4]}_unpack")

This in of itself doesn’t do much but you place Gibbed.Borderlands2.SparkTmsUnpack.exe down into ./Executables.
You can also download a full rip of what it was when I made that here.

Then it’ll use some of the info in the SparkTMS package to request Gearbox’ services for Hotfixes.
It requests these hotfixes over at https://discovery.services.gearboxsoftware.com/v2/client/steam/pc/poplar/verification.
This is a fairly simple JSON structure, it just defines individual services.
The proper hotfixes (technically called Micropatches) are (currently) in the 8th (0-indexed) entry in the services array
The current version (as I write this) for the Micropatch service is: "1.89.71"
It seems to use some sort of weird in-between version of BL2s hotfixes and BL3s new hotfix format.
