Possible interupt timing issue in rondo of blood

On stage 5, on real hardware there seems to be some sort of displaced video line at the very bottom of the screen(possibly caused by some sort of pallette change while the screen is drawing), but it does not appear on mister. I do not currently have the ability to test this my self, but I did notice it in some youtube videos.

They just seems sprites flickering tho, could be anything, why would you say it's a timing issue ?

Not necessarily timing, but just some quirk mister isn't replicating for some reason. My best guess is timing because it seems to be(from my limited knowledge) cause by a raster interupt.

"There's a detail about the PC Engine which is not in any emulator to my knowledge. When the CPU accesses palette data during active display, the VCE displays the *previous* pixel's color, creating 'streaking'.
