The visible area was changed to fix #1469. Since that one is verified on PCB, and the two games most likely run on the same PCB, I have to assume that the visible area in ldrun3 is correct unless a test on the real PCB proves otherwise.

I have a "LDRUN3JP" PCB... it's just too bad i can't record any video of it since no IREM (m62) games sync with my capturecard but i could try to explain with words :-)

At the title there is a black border at the bottom both MAME and PCB does this so it's correct so far but then on the PCB just before the scrolling upwards begin the topmost graphics "one bricklayer" disapear and nothing is added at the bottom so the visible area is small and it's not until the scrolling is complete that the whole screen fills with graphics "top and bottom bricklayer graphics" is added.

I hope this explanation is understandable? :-)

I don't understand sorry. Could you please try to reexplain what's different between MAME and PCB?

I have uploaded an animated gif to show how the PCB behaves.
Just before the scrolling begin the top graphics disapear, so when it scrolls there is no graphics shown at bottom and top where the black areas are and it is filled only when the scrolling ends.

thanks, it appears that the hardware can control masking of the top and bottom rows.
