0xE0 did indeed do the trick. Bob Rakosky pulled it out of some code he had written and let me know yesterday. Since then I managed to wade through some docs on the blitter and understand where the 0xE0 came from (ABC|ABNC|ANBC) but I still don't understand *why* it works that way. I tried various combinations of A, B, and C trying to figure out which was the source, which was the destination, and which was the mask, but I couldn't come up with one which worked. <sigh> I guess I'll just follow the docs blindly for now… –>Steve Bennett
