Use the tool to learn how a particular mechanic was implemented.
If your goal is to become a better programmer, decompiling commercial games is actually a highly inefficient way to learn. Recompiled code is messy, missing context, and lacks documentation.

A decompiler is a tool that attempts to reverse the compilation process, turning an executable game file (like a .exe ) back into a human-readable format. For GMS2, this typically means extracting: : The core logic of the game. Sprites and Textures : Visual assets used in the project. Audio and Room Data : Sounds and level layouts.

While there is no "official" free decompiler provided by the developers of GameMaker (YoYo Games), the community has developed open-source tools capable of reverse-engineering projects exported via the method. Projects compiled using the YoYo Compiler (YYC) are significantly harder to decompile as they are turned into native machine code rather than bytecode.

Even if such a tool did exist, using it on commercial games is illegal and unethical. You risk legal action, community blacklisting, and infecting your computer with malware. Use the tool to learn how a particular

Finding a reliable, free decompiler requires looking toward open-source communities. Because YoYo Games (the creators of GameMaker) does not officially support reverse engineering, these tools are built by independent community members.
