Required SDK Install

MSBT now targets SDK 03 / oak2-mod-manager v0.3. Before installing MSBT, update Borderlands 4 to the current SDK/mod manager stack:

Download oak2-mod-manager v0.3

Older SDK 02 installs are not the target for current MSBT builds.

Download Latest

Go to the GitHub Releases page and pick one file:

What you want	Download this	Notes
Recommended normal install	MSBT-Installer-v...exe	Windows installer. Adds app shortcuts and installs the bundled SDK mod plus ActorScriptDeployer into the detected Borderlands 4 sdk_mods folder.
Manual install / no installer	MSBT-Portable-v...-win-x64.zip	Extract it yourself. Electron app files plus bundled SDK mod/update resources.
Source code only	GitHub Source code (zip) / Source code (tar.gz)	For developers. This is not the ready-to-run app.

Do not manually download latest.json, latest.yml, or .blockmap files. Those are update-system files used by the app/installer.

Older beta/pre-1.0 packages remain available on the Releases page as historical rollback builds.

Quick Install

1. Install or update to oak2-mod-manager v0.3.
2. Download the current MSBT-Installer-v...exe installer from GitHub Releases.
3. Run the installer. It installs the Electron app, MattsSDKBoostingTools.sdkmod, and the bundled ActorScriptDeployer/ dependency.
4. Launch Matt's SDK Boosting Tools. If your Borderlands 4 folder is not in a standard Steam library path, use the Updates tab to browse to sdk_mods and run Install / Update SDK Mod.
5. Start Borderlands 4 with the SDK loaded.
6. Use the app's Refresh Status / target controls before sending live actions.

Expected game-side layout after installer or updater:

Borderlands 4/
  sdk_mods/
    ActorScriptDeployer/
      __init__.py
      pyproject.toml
    MattsSDKBoostingTools.sdkmod

Manual ZIP users can still extract the portable package and copy MattsSDKBoostingTools.sdkmod plus the bundled ActorScriptDeployer/ folder into sdk_mods manually. The Dev Spawner tab needs ActorScriptDeployer.

The current public direction is:

• Keep the original BLImGui panel available when BLImGui is installed.
• Make BLImGui optional.
• Run live game actions through a small SDK bridge.
• Move non-game UI/catalog/serial/build logic into the Electron app.
• Keep the older Tkinter app as legacy/reference code only.
• Package Electron with the bundled SDK mod, ActorScriptDeployer, resources, and a portable Python runtime.

Package Contents

Current Electron installer/portable packages contain:

Matt's SDK Boosting Tools/
  MattsSDKBoostingTools.exe
  resources/
    sdkmod/
      MattsSDKBoostingTools.sdkmod
    sdkmods/
      ActorScriptDeployer/
    external_app/
    python/
    releases/

Build From Source

Users who do not want to run a prebuilt EXE can build it locally.

Requirements:

• Windows
• Node.js / npm
• Python 3.13

The Electron build bundles a portable Python runtime so normal users do not need Python installed.

Build the Electron app:

.\build_electron_beta.ps1

Build the Electron Windows installer:

.\build_electron_beta.ps1 -Installer

Publish release assets to GitHub Releases instead of committing ZIP/EXE files to source:

.\publish_github_release.ps1

Check the synchronized Nexus Mods file list:

.\tools\check_nexus_release.ps1

Versioning and asset naming are documented in VERSIONING.md. Nexus release sync is documented in docs/NEXUS_RELEASE_SYNC.md.

What Replaced BLImGui

The main user-facing app is now the Electron desktop app. The older Python/Tkinter app remains in the repository as legacy/reference material.

BLImGui-specific code is still kept in the SDK mod as an optional in-game UI. The Electron app does not import BLImGui, unrealsdk, mods_base, or live SDK modules. It talks to the SDK mod over HTTP for live game actions only.

More detail: BLImGui Replacement Architecture.

Live Game Boundary

The external app owns local tooling such as:

• serial conversion
• serial parts breakdown
• BL4 Codes catalog search/details/bookmarks
• Validator
• Legit Builder UI state, filtering, validation, and serial generation
• item pool and travel browsing

The SDK bridge owns live game actions such as:

• giving serials to selected/all/non-host players
• currency, XP, SDU, inventory size changes
• item pool spawning
• map/station travel
• movement/debug/dev commands
• chest, bank, shiny, and live player actions

Known Multiplayer Note

Selected-player serial delivery currently uses the game's all-player reward package path, then patches the intended target package. This is a game/API workaround and can create extra base reward behavior for non-target players. Do not delete non-target reward mail unless the package can be identified with high confidence.
