Ultimate ASI Loader
What Ultimate ASI Loader is
Ultimate ASI Loader is a Windows proxy DLL for adding ASI plugin loading to supported games. It loads custom .asi libraries into a game process that uses supported Win32 or Win64 DLLs, including Direct3D, DirectInput, audio, and XInput libraries. To install it, place the loader in the game directory, commonly named dinput8.dll, or give it another supported DLL name. Put ASI files in the game root or in a scripts, plugins, or update folder. When configuration is needed, use global.ini in the scripts or plugins folder; the selected DLL name can also be used as the INI filename.
The update folder can supply replacement game files while leaving the originals in place; removing the folder restores the original files. For many supported DLL names, the loader can also pass calls to the original DLL if it is renamed to a Hooked.dll filename. Other documented options include d3d8to9 support when the loader is named d3d8.dll, and crash minidumps and logs when a CrashDumps folder is placed beside it. The 32-bit build includes a legacy windowed-mode feature configured through wndmode.ini, with settings that may need adjustment for each game. Win32 and Win64 builds are described, and the repository lists an MIT license.
