BepInEx vs Hell2Modding

BepInEx is a plugin and modding framework for Unity Mono and IL2CPP games, as well as .NET Framework games such as those built with XNA, FNA, and MonoGame. It provides configuration and logging, runtime method patching, and in-memory assembly patching. Runtime patching uses Harmony, including HarmonyX and MonoMod; in-memory patching uses Mono.Cecil with UnityDoorstop. The installation guide lists Windows, Linux, and macOS, though supported operating system versions and architectures depend on the build and game. Setup is manual: download the appropriate build and put its contents in the game’s root folder. Official binaries are available as stable and bleeding edge builds; the documentation recommends stable in most cases and notes that bleeding edge builds tend to be buggier. The project is open source under LGPL-2.1 and links to guides for users and developers. Compatibility has limits: stable releases are available only for Unity Mono, BepInEx 6 documentation remains a work in progress, and BepInEx 5 plugins do not yet work with the 6.0.0 pre-release.

Hell2Modding is a free modding plugin and framework for Hades II, for players modifying the game and developers building mods for it. It uses ReturnOfModding as its base and lovely-lib for runtime patching. The main loader, d3d12.dll, goes beside Hades2.exe in the game's Ship folder; removing or renaming that DLL returns the game to an unmodded state. The project links to instructions for installing with r2modman, a community-created mod template, and the Hades Modding Discord. It lists Windows support and Steam Deck support through Proton, and uses injection to load mods. Plugin support, load-order control, and mod profiles are listed. The GitHub repository lists an MIT license. Its Releases page has a Nightly build created by GitHub Actions, with a SHA256 value and instructions for checking the downloaded DLL. The listed plan is free, with no plan limits stated.
