In their own words
Cyber Engine Tweaks
Cyber Engine Tweaks is a free framework for scripting mods for Cyberpunk 2077 with Lua and access to internal game scripting features. It includes a Dear ImGui interface for mods, a console and a TweakDB editor, along with developer options such as diagnostics, assertions, a debug menu and logging game options. Included patches can be enabled or disabled through settings or configuration files, though changes require restarting the game. Examples include removing pedestrians and traffic, disabling temporal antialiasing, suppressing intro movies and skipping the start menu. RED4ext is a prerequisite. The project distributes current releases through GitHub Releases and provides wiki documentation for installation, usage and modding. Windows is supported; Linux instructions cover use through Proton, including Steam and non-Steam/Wine setups. Release notes for Patch 2.31 list support for game version 2.31. The repository includes an MIT license permitting use, modification and distribution subject to its conditions, and provides the software without warranty.
Fallout 4 Script Extender (F4SE)
Fallout 4 Script Extender (F4SE) is a free Windows resource for Fallout 4 modders who need expanded scripting capabilities. It extends scripting without changing the game’s executable files on disk. Listed interfaces include the Papyrus plugin API and hooks for Papyrus, Scaleform, and the classic script system. The homepage lists build 0.7.9 for Fallout 4 runtime 1.11.240. F4SE supports Fallout 4 releases from Steam and GOG, while MS Store, Game Pass, Epic, and other Windows Store versions are unsupported because those applications do not provide required APIs. Native code plugins require updates from their creators for runtime 1.10.980 and later, and plugins must have publicly available source code. Injection loads mods and may trigger poorly written virus scanners. Additional utilities include a command-line BA2 archive extractor and PEX script disassembler. The project is provided as-is and directs installation questions to its subreddit.
