Non-interlaced NTSC
Is there anyone that can explain how exactly non-interlaced NTSC works? I've heard a few reasons for it.
One is the last scanline is only half a scanline in interlaced modes, and in non interlaced modes, the last scanline is a full scanline.
But then I've heard others where the VSync has extra pulses to prevent the two fields from advancing basically.
So what exactly causes interlacing and no interlacing?
