Sprite per scanline question
I understand there are 8 sprites per scanline. But what happens if the sprite spans multiple scanlines. How does the nes keep track of that?
Re: Sprite per scanline question
Each scanline is processed independently, and while a particular sprite may be skipped on one scanline because there are 8 higher-priority sprites on that scanline, it may be drawn on some other scanline where that's not the case. Drawing an 8x8 sprite tile is not all-or-nothing.

Re: Sprite per scanline question
I remember once finding that confusing as well. Similar to how tech sheets saying "SNES has 256 colors onscreen at once and can do transparency" was confusing to me because it made me think "how the hell am I supposed to make sure transparency effects never go over 256 colors?"
