Senior Tester Sep 11, 2018, 01:03	namcona1.cpp: Added dynamic screen visible area change effect, used mostly by Numan Athletics on transitions [Angelo Salese] https://git.redump.net/mame/commit/?id=266c662794249c25916cf769395d83a5697aa1ea This dynamic screen visible area change looks ugly and could certainly be programmed without stripes!

What's annoying is that X-Day 2 uses the background color for the flame effects, pretty likely there must be an unemulated behaviour there. The stripes dimension is correct anyway, it's really intended to cut off one line at top/bottom as proven by the video. (Also all of this is noted in source anyway)
