Can you give an example different from the above?
SNES Game that's finished but needs still draw/redraw stuff. STP will mask the NMI from the VBLANK signal, which is how the game knows to load stuff into VRAM on the PPU, so it can be sent out on the multiout connector when the VBLANK is done.

Surely drawing and redrawing stuff is a side-effect, no?
