Complete border isn't an authentic feature, but it does help with aligning timing-sensitive code like yours. The default view area is balanced for normal use, but you lose some lines from top and bottom. "TV-visible" adds those back, and is needed to see the top border scroller above Lyra 3's bouncing ball. TV-visible combined with the 5:4 display ratio option give something that more closely resembles real SAM TV output, though on Vista and Win7 it'll look a bit blocky I finish merging in the new D3D support. I _think_ the normal SAM border is only 16 pixels, compared to 24 pixels for the Spectrum. Though I'm not sure if any visible output is generated beyond that (Colin?). Si
