Space Invaders Deluxe pcb issue

Working on a SID boardset that runs regular SI code just fine, but won't run the Deluxe roms. I modded the board for the single rom hack, and it still has the same symptom...which is being stuck at the player/score info at the top of the screen. This redraws at about 2-3hz rate and does nothing else. I'm thinking its gotta be something to do with the sound board since SID code won't run using a regular SI sound board. What's the mainboard looking for from the sound board to run SID code?
