ModTek vs Starfield Script Extender

ModTek is a free mod loader for HBS’s BattleTech PC game. It loads mods at game startup when they use the mod.json format, allowing modders to package self-contained changes without overwriting game files. It resolves dependencies and controls load order without requiring edits to VersionManifest.csv. The project says newer versions include DLC support not present in BattleTech’s built-in 1.7 loader. It supports BattleTech installations from Steam and GOG on Windows, Linux, and macOS. Installation uses a downloadable ZIP extracted into the game’s installation folder; the instructions warn that the game should be outside Program Files because Windows UAC protection can interfere. Version 3 and later use UnityDoorstop to load ModTek without modifying game files. The repository documents JSON and DLL mods, advanced JSON merging, manifest manipulation, and HarmonyX support. The project is licensed under LGPL-2.1. Linux instructions describe a system-wide ASLR change as an obsolete, insecure workaround and provide an environment-variable fix instead.

Starfield Script Extender (SFSE) adds scripting capabilities and other functionality to Starfield on Windows. It supports only the latest Starfield version available through Steam; the Windows Store and Game Pass editions are excluded. The official site lists build 0.2.21 for Starfield version 1.16.244. SFSE supports plugin loading by injection, with a plugin manager, a Scaleform menu plugin interface and preliminary support for custom Papyrus native functions listed in its changelog. Updates to Starfield have sometimes required plugins to be recompiled or their compatibility data changed. Installation uses Steam or the installer, followed by copying the DLL and EXE files into the Starfield folder rather than its Data folder. The game must then start through sfse_loader.exe. SFSE components use a code signature intended to reduce virus-scanner false positives. The software is free, with a listed plan price of free.
