Summary	00480: bosco and clones: About the graphic of title screen.
Description	If you let either an old or new version of Bosconian run through the attract mode, you will see the title scroll onto the screen over a gray background. Then that background will get wiped away to reveal the starfield beneath. But in 0.80 a vertical portion on the left side of that gray remains after the initial wipe and only gets erased as other objects come on screen. I believe the entire gray area is supposed to be wiped away all at once. The attached screenshot should show an example of some of the gray area remaining on the left side. Follow-up by Tafoid in 0.116: Regression appears to be 0.79u1, according to massive work with driver in whatsnew.txt notes. I don't have that U version to test, but it's confirmed not happening on 0.79 official release and happening on 0.80.

As you can see, the title is shifted slightly more to the left, making the gray part off-screen. This is (also) not correct though: the distance between N and the radar is too large when compared to pcb. It's possible that the left couple of pixels are not (or not supposed to be) visible on the pcb with an arcade monitor, so I've set this bug to [possible] until further research.
