So I got everything hooked up tonight, and the good news is that I have definitely made some progress!
It appears to work, although the video is currently scrolling with multiple video problems, but I definitely have something to work with!

Congratulations on the progress! Looks like maybe some problem with HSYNC to iron out?
I’m really not sure yet. If my initial look into it is right, I think there’s something going on with my four different banks.
I have four dual-port RAMs and essentially write into one, and then read from it a line or so later.
I have some concerns with synchronization where the output monitor might be “Blanking” but the input is still writing.
I’ve been dealing with stuff in a “streaming fashion” completely irrespective of vertical sync. So the receiving data clock and transmitting clocks have no relationship.
More on this later.
