What xOBSE is

xOBSE is a community-maintained, up-to-date fork of the Oblivion Script Extender, a tool that expands scripting capabilities for modders of The Elder Scrolls IV: Oblivion. The project is free and open source, with a downloadable release and public source code on GitHub. It supports Steam and GOG versions of the game, with GOG preferred; Direct2Drive is unsupported. The README identifies English official patch v1.2.0.416 as supported and warns that localized editions with different executables or patches may not work. On Linux with Steam Proton, users are instructed to rename obse_loader.exe to OblivionLauncher.exe and start the game through Steam. xOBSE does not alter the game executable files on disk, so it has no permanent side effects. The project aims to preserve compatibility with existing mods and plugins, although beta releases may introduce unintended errors. Mod Organizer 2 users need additional setup instructions. The repository also includes an example plugin project; developers defining commands need an opcode allocation from the maintainers.
