When the game runs, the GameMaker runner executable reads this data file and interprets the bytecode on the fly. 2. The YYC (YoYo Compiler) Export The YYC export is used for performance-heavy games. It translates GameMaker Language (GML) code into C++ code.

This is a complex task that requires in-depth knowledge of programming, reverse engineering, and specifically, the GameMaker Studio 2 engine. Here's a simplified overview of steps you might consider if you were to attempt putting together a piece of a decompiler: gamemaker studio 2 decompiler
A GameMaker Studio 2 decompiler is a dual-use technology. In the hands of a developer recovering lost work or a community creating localizations, it is an invaluable tool for preservation and creativity. In the hands of bad actors looking to clone or pirate software, it poses a security threat. By understanding how GMS2 compiles data and utilizing the YoYo Compiler, developers can successfully safeguard their creative investments while respecting the technical curiosity of the broader engineering community.
: The design and placement of objects within the game levels. Top Tools for GMS2 Decompilation When the game runs, the GameMaker runner executable
Rebuilds object properties, event structures, and level layouts.
It translates the compiled bytecode back into human-readable GameMaker Language (GML) scripts, event codes, and creation codes. It translates GameMaker Language (GML) code into C++ code
of the software. These tools should generally be reserved for personal project recovery or sanctioned modding. Project Integrity
Even if a decompiler partially works, you will face:
Instead of generating bytecode, YYC translates GML code into highly optimized C++ code.
