The conversation around DRM in GameMaker is not purely academic. In November 2012, a disastrous GameMaker: Studio update caused its anti-piracy system to malfunction, targeting legitimate paying users. The update began permanently replacing sprites and other game assets in their projects with a skull and crossbones image. Many users lost hours or days of work. This incident is often cited by critics of aggressive DRM and serves as a strong rationale for why some developers and users prefer to use tools that bypass such systems entirely, even on legal copies of software.
If you want to understand how the engine compiles files, YoYo Games offers free versions of GameMaker for educational use, allowing you to build and test your own projects cleanly.

Instead, take the skills you would use to run the patcher and apply them to learning real software engineering. Reverse engineer malware for a cybersecurity firm. Mod games with permission from the devs. Build your own engine.
The 2021 iteration of this tool gained traction due to its automation and compatibility with games built on GameMaker Studio 2. Its primary functions include:
