It tricked me at first too . I could see experimenting with the algorithm more to better recognize transparent pixels. The current algorithm is fast though.

As you already know, my knowledge of the 68040/60 and the according optimization is nearly zero. But I will make use of your hints, of course. THANKS!
It's never too late to learn . The Natami N68k processors are designed very similar to the 68060 so it will become more common. The change/use penalty is explained in this Natami thread...

I've improved my understanding and assembler coding from this thread as some concepts like this are not documented very well.
