AC3MP Skip Intro

Skips the startup disclaimer and Ubisoft logo in the original 32-bit multiplayer executable of Assassin's Creed III.

The patch runs entirely in memory. It does not delete, rename, or replace any .bik video, and it does not modify AC3MP.exe on disk.

Features

• Skips warning_disclaimer.bik and ubi_logo.bik at launch.

Installation

1. Download dinput8.dll from the latest GitHub release.
2. Copy it into the game directory, next to AC3MP.exe.
3. Start the multiplayer game normally.

No ASI loader is required. If another mod already uses dinput8.dll, the two proxies cannot simply be installed at the same path.

Building from source

Requirements:

• Windows 10 or Windows 11
• Visual Studio 2022 with Desktop development with C++
• CMake 3.20 or newer

Open Developer PowerShell for Visual Studio 2022 in the repository folder and run:

cmake -S . -B build -A Win32
cmake --build build --config Release

The resulting file is:

build\Release\dinput8.dll

The project must be compiled for Win32; a 64-bit DLL cannot be loaded by AC3MP.exe.

Troubleshooting

The DLL writes ac3mp_skipintro.log in the game directory:

• startup sequence completed means the skip ran successfully.
• executable not recognized or patch failed means the installed executable is not supported or its relevant code differs from the expected build.

If the game does not start, remove dinput8.dll first to confirm whether the proxy conflicts with another mod.

The approach was inspired by the SkipIntroVideos feature in Sergeanur/EaglePatch.
