graphics - Old 8 bit retro video emulation - sprite drawing -

i'm trying understand how sprites drawn onto scanlines of example vdp 9929a graphics chip, emulation.

there limit of 4 sprites per scanline, mean cannot have more 4 sprites same y coordinate?

if cascade them draw 32 sprites on each line below 1 , 1 pixel right of each other overlapping each other, result in centre of 16 sprites being drawn on same line. still drawn correctly not scanline relating starting y coord. hope i'm making sense.

thanks in advance.

there can no more 4 sprites on single scanline; additional sprites' horizontal pixels dropped. sprites higher priority drawn first.

in other words, each line, chip draw 4 sprites highest priority exist on line, not start on line.

....where 1 highest prio, scan line 1 draw sprite 1,3,5, scan line 2-4 draw 1,2,3,4, scanline 5 draw 2,4,6.
