The emulation side doesn't keep it as a pure offset, but from what I remember it should still be relatively easy. There might be some funky side-effects for attributes in mode 1, of course. > a) tell the difference between a normal address request and an ASIC request The display accesses are in a fixed pattern and offset from the start of the frame, so I'd hope they could be singled out (still assuming they can be seen and overridden). It would also mean tracking the current display mode to make adjustments for the layout differences. Mmm, sounds like it's getting complicated and expensive already. > I don't even think the ASIC memory requests appear on the bus, do > they? Colin would know :) Beats me :) Si
