I've just downloaded my first game off GOG (HOMM II Gold) and every time I play more than 5 minutes, the DOS emulator fails. Any ideas?
What's your operating system? System specs (Ram, CPU, video card)?

That information can help us figure out what's going on.
What do you mean by "Fail"? Does it crash? does it give you an error message?
