target are much easier to decompile because they contain bytecode. Games compiled with the YYC (YoYo Compiler) are turned into machine code ( ), making them significantly harder to reverse-engineer. Legal & Ethical Use : Decompiling games typically violates the End User License Agreement (EULA)
GameMaker Studio 2 compiles projects into platform-specific binaries and packaged game assets. “Decompiling” in this context usually means extracting resources (images, sounds, objects, rooms) and recovering GameMaker Language (GML) code or equivalent logic from a built game.
Older, legacy command-line tools like targeted GameMaker 8 and early Studio 1 formulations. While largely outdated for modern GMS2 targets, they laid the structural groundwork for how modern tools parse GameMaker's proprietary format. The Legal and Ethical Landscape
