Then, as before, the bottom of the box suddenly disappears from under the "Nintendo" logo and reappears under "Challenge". For excitebkj: attract mode unchanged, segment still slowly scrolls along. In qualifying courses erratic flickering/movement is gone, but the end of race still has the same glitch as the other two sets. It's worth noting, as was mentioned on mameworld, that both NES and PC10 have related issues with this scanline in at least some of the Excitebike sets.
