Create a brand new folder directly on the root of your drive (e.g., C:\Emulators\ or C:\Games\ ). The exception hadn't just crashed the game; the

In the context of saving a ROM (your game file) to disk (your hard drive or SSD), the emulator tried to write data, but the operating system threw back an error that the emulator wasn't designed to handle. Common underlying reasons include:
