GameMaker Mass Mod Patcher (abbreviated to GM3P) is a tool used to merge multiple xdelta mods for GameMaker games and thus be able to play multiple mods at once.

This tool is currently used in the backend of Deltamod for mod merging.

1. Make sure you have .NET 8.0 or later and Git installed
   
2. Open the .sln up in VS or Jetbrains and build the project "GM3P". (IDK about other IDEs like VSCode)
   
3. Open the .sln up of UTMT-For-GM3P and build the project "UnderTaleModCli"
   
4. Copy and paste the UTMT build into the GM3P build under a folder named "UTMTCLI"
   
5. Copy and paste the contents of the "UTMT Scripts" folder under a folder named "Scripts" under "UTMTCLI"
   
6. Download xDelta3 v3.0.11 64-bit and paste it under the GM3P build.
7. Happy patching
