According to the screen report, my error is in D6.

So, from poking around and looking at the schem, D2 looks to be the main
program for the game itself. My intuition says the ROMs on the Video
Gen board would contain the sprites, so what exactly is in the other
ROMs on the CPU? More subroutine code? Also curious as to the 2 ROMs
in the G locations, G3 & G4.

I'm trying to build a picture of the memory map to help me wrap my head
around the flow of the game code.
