The general consensus within the gaming community is that decompilation is acceptable when confined to personal use, educational research, or transformative, non-commercial modding that requires ownership of the base game. It becomes unethical and illegal the moment it violates copyright, facilitates piracy, or damages the original developer's financial livelihood. How Developers Can Protect Their GMS2 Games
This bytecode, along with all game assets (sprites, audio, fonts), is packed into a single data file, typically named data.win on Windows, or embedded directly within the executable.
Before attempting to decompile, you must identify how the game was built, as this determines the difficulty of retrieval: Virtual Machine (VM)
