The irritating thing about about these ST ports that use software area fill even on the Amiga version is that these software area fill algorithms mostly amount to drawing horizontal lines -- a task that's easy to set the blitter up for, and fast if you don't bother to actually use line mode. You can just set the blitter to copy a small segment of a previously stored 320 pixel horizontal line.

So the programmer doesn't even need to use the Amiga's area fill option to get extra speed -- just basic blits.

Still too much trouble, apparently.
