I looked at it once, and if you fix the raster timing for this you end up breaking the raster timing in some of the driving games (fourtrax IIRC)

it's an off-by-one raster error anyway, much like nebulous ray has.

probably off-by-one due to other things with the system timing, or the exact point at which various registers actually take effect etc. being wrong.

Hi. I've discovered a workaround for this. Just enter service mode (F2) and flip the screen. Later in mame video options, flip the screen 0 at 180º.
Thank you.

Fixed by Haze.

Added "m_update_to_line_before_posirq = true; // prevents bad line on horizon"
to init_burnforc
