ScriptHookVDotNet vs Ultimate ASI Loader

ScriptHookVDotNet is free Windows PC script runtime software for Grand Theft Auto V Story Mode. It runs under Script Hook V and connects custom .NET code to the game, allowing scripts in any .NET language; the FAQ recommends C# for new coders. Object-oriented APIs provide guided interfaces and documentation for common GTA V scripting tasks. Scripts are built as .NET Framework class libraries and can reference the ScriptHookVDotNet3 package, including through NuGet, as well as arbitrary .NET Framework libraries. The runtime and scripts can be reloaded with SHVDN commands, although the runtime cannot currently reload after Script Hook V unloads all loaded ASI scripts. The project says official game versions are supported, while some advanced scripts may fail on certain versions. Requirements include Script Hook V, Microsoft .NET Framework 4.8 or later, and the x64 Microsoft Visual C++ Redistributable for Visual Studio 2019 or later. GTA Online requires removing SHVDN and related mods when an ASI loader is installed.

Ultimate ASI Loader is a free Windows proxy DLL that loads custom .asi libraries into a game process. It supports games using Win32 or Win64 libraries such as Direct3D, DirectInput, audio, and XInput. Installation usually means placing the DLL in the game directory as dinput8.dll, or renaming it to another supported DLL name. ASI files can be stored in the game root, scripts, plugins, or update folder. When needed, global.ini belongs in scripts or plugins, and the selected DLL name can also serve as the INI filename. The update folder can hold replacement game files while originals remain untouched; removing that folder reverses the change. The loader can forward many original DLLs after renaming them Hooked.dll, and d3d8to9 support is available when it is named d3d8.dll. Crash minidumps and logs are created when a CrashDumps folder exists beside the loader. Win32 and Win64 builds are available, including smaller NoPDB archives. The repository lists an MIT license.
