Ahhhm, I do this anyways. You have to do this, really, to accomodate as many games as possible displaying within the boundary of the screen. I don't bother with interlace resolutions, though......
> There is a workaround for this: Run the desktop at a non-interlaced res such as 640 x 288. This might mean using a front end which has a 640 x 288 mode such as Mamewah.
