I get ugly flicking of my TV when I quit a game from MAME. I assume this is from the resolution changing, is this right? Can I get around this by setting MAME and my desktop to the same resolution?
I've got my desktop set to 800x600@16bit, 60hz, and edited mame.ini to do the same, though I'm not sure if my mame.ini file is being read or not - I had to create one manually... maybe GameEx uses a custom one?
