Now I know this can be done with low-level >bliter calls, but I can't seem to figure out quite how to do it. Is this possible? My reading of the hardware manual suggests it is not. What would be the hardware basis for it (what blitter mode did you think will do it)? If there's a hardware mode ... there might not be software support for the mode, but there IS support for programming the blitter directly without taking over the system...
