Gamemaker Studio 2 Decompiler |work| Jun 2026
GMS2 compiles GML code into an intermediate bytecode. This bytecode is packaged into a data file (usually named data.win on Windows or game.ios on mobile). When the game runs, the GameMaker runner executable reads and interprets this bytecode on the fly.
Developers occasionally lose access to their original source code due to hardware failure, corrupted backups, or accidental deletion. A decompiler allows them to recover their own work from a published executable.

It then compiles that C++ code directly into machine code using a platform-specific compiler (like Visual Studio or Xcode).
Which (Windows, Mobile, Console) are you deploying to? Do you currently use the VM or YYC compiler ? GMS2 compiles GML code into an intermediate bytecode
This study examines the state of decompilation for GameMaker Studio 2 (GMS2): what GMS2 compiles into, why decompilation is hard, existing tools and approaches, technical details of bytecode and YYC, legal/ethical considerations, practical use-cases, and recommended best practices for developers to protect or recover code.

To understand decompilation, you must first understand how GMS2 builds a game. GameMaker offers two main export targets: 1. VM (Virtual Machine) Developers occasionally lose access to their original source
The GameMaker Studio 2 Decompiler: Reverse Engineering, Security, and Asset Recovery
Malicious users can steal proprietary logic or art assets to re-skin and sell games.
The Ultimate Guide to GameMaker Studio 2 Decompilers A is a specialized reverse-engineering tool designed to convert a compiled game back into human-readable GameMaker Language (GML) or a project structure. While often used by modders to add features to popular titles, these tools also serve critical roles in data recovery and educational analysis. How GMS2 Decompilation Works
If you must use the VM export for compatibility or debugging reasons, do not leave your data.win file out in the open.
