To do sprite animation in Pixel Pup, I loaded all of the tiles of all of the frames into video ram at once. Then to animate the sprites update which tiles are their current one.

But most commercial games did it differently. They keep the sprite using the same tiles, and copy frames into that tile location over time to accomplish the animation. This uses fewer tiles, but the game needs to copy the tile data into vram fast enough to get smooth animation without any tearing.
