Patcher: Universal Gamemaker

The Universal GameMaker Patcher (UGMP) is a powerful tool designed for developers and gamers alike, aiming to simplify the process of modifying and enhancing GameMaker Studio projects. This write-up provides an overview of UGMP, its key features, and a step-by-step guide on how to use it effectively.

A universal patcher relies on parsing the specific format of the GameMaker data package. The binary data is organized into distinct chunks: Chunk Name Description Patching Application General information and game settings Changing window options, icons, and titles SPRT Sprite properties and texture coordinates Swapping visual assets or modding skins CODE Compiled GameMaker Language byte-code Injecting custom scripts, cheats, or logic fixes STRG All text strings used within the game Fan translations and text adjustments SOND / AUDO Audio asset configurations and pointers Replacing background music or sound effects Common Use Cases

GameMaker compiles assets, code, and configurations into structured data packages. The patcher scans these packages to inject code, alter variables, change asset pointers, or bypass engine-level restrictions across various games without needing the original source code.

Using scripts within UndertaleModTool, HgPatcher can create a patch by comparing a vanilla game file with a modded one and then apply that patch to a fresh copy of the game. The patch distribution model is safer for mod creators and users, as it reduces copyright infringement risks by not including the original game assets.
