Not all GameMaker 8 games decompile successfully. Games that have been modified after compilation, protected with third-party tools, or built with unusual configurations may fail. If you encounter problems, consider checking the OpenGMK GitHub issues page or searching community forums for similar reports.

When the decompiler first appeared around 2010, it sparked massive debate:
