Big thanks for very quick answer.
I confirm I can view the captured data with downloaded software. As I expected the RGA bus is idle during additional cycles of WAIT.
Now I'm doing further copper timing research. Still don't know when actual comparision takes place. My Minimig's copper code is late in WAIT's about 8 lowres pixels. I would be interested in more captured data files if you have any and be so kind to share them
(I mean not only copper but blitter would be interesting although I haven't touched it yet).
