Hey all. This is what's going on. I've tested the roms with my programmer and they check out. I've also installed a Braze HSS kit simply for the diagnostics and it shows all RAM and roms ok. Any tips where to start would be great. Thanks.

Looking at this:

Images similar to what you have are from the ROMS at 7C, 7D, 7E, and 7F. If those EPROMS are good, then it is probably related to the hardware around it. I would probably look at 6H and 7H to make sure the addressing is correct (nothing stuck or weird looking on the scope). It might be something else like one of the 299's at 8C, 8D, 8E or 8F.

Since the background information looks correct, it would be good to know where those are stored compared to motion objects to help narrow down where the issue might be.
 
All of my sprites I'm waiting for the 3e counter 163 chip I think that causes sprites issues but waiting for it to see coul be in that area maybe
