I'm doing some copper list stuff now and have run into a
little hitch. I have my copper list, but what is the
fastest proper way to install it. It is easy to just
set up the hardware address register but is this the
correct way.
My program can not afford the wait involved in letting
the system building the copper list from the ViewPorts.
So I build my own custom list to do want I want. In
fact I have two copper lists and I plan to do page
flipping by switching copper lists. So my real
question is what is the fastest safe way to switch
the copper lists.
Thank you,
Wayne Knapp
Ps. Durning the time my program is messing with copper
lists, I'd shut down the multitasking. This because
what I'm trying to do requires every cycle that Amiga
can give.
