Great explanation.

F-Zero managed to do the “change zoom on each scanline” trick without a coprocessor in the cartridge, didn’t it?

F-Zero was a launch title that didn’t use anything specifically for graphics. It used the same cartridge board as Super Mario World.

Mode-7 scaling can be modified per scanline to get the textured-plane effect seen in many games (e.g. F-Zero), without any additional hardware.
