Start with mame warriorb -window Change in 'Video Options' menu to Dual Side-by-Side (Gapless). Now change with the PC mouse MAME's window several times from small to large and vice versa.

No.15479 hap Developer Sep 18, 2018, 12:55	It's due to rounding layout screen element edge coordinates (same thing with rect element). You will get this in every gapless dual screen game, either a black seam or more likely a column/row of pixels that's slightly thinner.
