33's Range Over

33's Range Over is the PPU limitation that it can only render 32 sprites per scanline.

If 33 or more occur on a single scanline, the excess will dropout, and the OBJ Range Over Flag (bit 6 of STAT77) will be set. This flag will be cleared at the end of vblank, but not during fblank.

Sprites hidden by windows or other sprites still count towards the total, but sprites completely off-screen do not. Large sprites do not count as multiple smaller sprites.
