Atari Game Tools: Atari STE game engine - Giant Boss Sprites
Recent upgrades to AGT allow huge sprites to be drawn efficiently and without hacks on Atari STE.
Previously sprites could only be drawn up to 32 pixels wide using the high performance sprite paths. That limitation has been removed.
Here a combination of 32, 48, 64, 80 and 144-wide sprites are drawn together over a scrolling playfield.
