MelonLoader vs ModTek

MelonLoader is a free mod loader for Unity games using Mono or Il2Cpp. It injects mods and supports plugins, load-order control, and dependency handling. Mods and plugins are placed in separate folders in the game installation directory, and game logs are written to a MelonLoader/Logs folder. The project provides an installer guide and manual installation instructions for a release archive. For Il2Cpp games, the listed requirement is the.NET 6.0 Desktop Runtime; the repository says it is installed automatically on Windows. Windows startup loading uses a proxy DLL, a method the project identifies as Windows-only. Linux instructions cover WINE, Steam Proton, and native use, while Android and Oculus Quest support is marked as work in progress. Debug mode is intended for work on the loader, plugins, and mods. Configuration also includes a Mono debug server, and the Il2Cpp Assembly Generator can be set to run without contacting its remote API. MelonLoader is licensed under Apache License, Version 2.0 and listed at free.

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.
