I think the NES's PPU is a lot more powerful in some ways than the C64 VIC-II chip. The NES's PPU supports multiple background layers, priority, pixel collision detection and has up to 64 sprites on screen at once - albeit with some limitations on how many are on each scanline. The VIC-II can only do 8 sprites at a time without scanline raster tricks (and if we count those the NES can do more than 64 too)

See here for some clever examples of this technique. Everything that's overlapping is done with sprites: https://youtu.be/ZGyFQ9aRp_U?t=579 https://youtu.be/ZGyFQ9aRp_U?t=579
- ddtaylor 8y agoYou're right, I was thinking of the SNES which had multiple background layers.
