Is that actually really possible? Wouldn't that require 
something like a VDMX register? Or does it work with 
VDEL already?

How about sprites?

I thought about doing "Dog Patch" for a while, with two 
double-sprites on each side without flicker by executing 
this in one line:

Fill GRP1/2 -> Wait -> Change GRP0/1 -> Hit RESP1/2

But I gave up on the idea, because even if it worked to 
show both sprites on the other side again, they'd have a 
one pixel gap there, since the second RESP takes 3 
cycles resulting in a 9 pixel shift...

Yes? Tell me more please!

Hm... All that brainstorming got me really into trying 
it. At least I'll try to do the kernel to see if 
everything works as planned. Hehe, actually I already 
started, but I only have the boulders done yet... ;-)
