CustomGMExceptionHandler is a tool to make a custom Gamemaker games' exception handler system.
To be specific, I used exception_unhandled_handler() and game_change() in order to make it work.
exception_unhandled_handler() will let us handle the exception by ourselves,
game_change() will let us change the client into CrashHandler.win.
This project was compiled in 2024.6.2.162 IDE, 2024.6.0.205 Runtime. Somewhat old versions may work, But very old ones will not.
