Yeah, it works fine in fullscreen mode when not launched thru mamewah, but it still hangs in fullscreen mode when launched thru mamewah without the wrapper and just using the x64.exe. I still think it's a video settings problem but it's strange b/c I have no problem with any other emulators. I'm hoping installing my new Betson monitor with an arcade VGA card will solve my problems - I guess we'll see. Oh, thanks for the reply and Mamewah is EXCELLENT!!!!
