In line mode the HRM asks you to fill in BLTAPT (high and low) with dy4-dx2 as a long word.

However, I've seen demos that don't set BLTAPTH and in my own code I can set it to anything and things still work fine.

So, it seems safe to assume the blitter ignores the high word.

Might be common knowledge, but I didn't see it in this thread and it was news to me.
