Hi Folks, I need some help if you have time.

Im running DEMUL on a Windows 10 PC, i7, GTX1060 etc - and the software emulates really well but the game's seem to freeze up within about 10 minutes or so of launching. Oddly, the emulator is still workable and the OS is fine - just the game window (in window or full screen). Any thoughts or suggestions? Ive tried a bunch of settings changes but havent been able to improve things one way or the other. Is there any kind of de-bug log I could maybe take a look at?
