Any ideas what's causing this? pcb was working fine prior to this, then this fault appeared and has stayed. Voltage is good, running at 5.05v board side. |

This is a most likely problem with a sprite ROM, or accessing the sprite ROMs.
How are the in-game sprites, they look ok from your screenshot?

The crowd at the start of the game are corrupted, but in game everything is fine apart from the lady's hair. Just realised I haven't actually done a rom test which should have been first on the list d'oh, I'll do that now!

The ROM/RAM test doesn't check the sprite ROMs.
It will verify the sprite RAM for you though.

Yeah that's come back all good. Nothing is affected in game other than the guys in the car and the other bits in the photos. Which roms should I check?

Check the second bank of sprite ROMs:
mpr-10372 ic13 mpr-10374 ic14 mpr-10376 ic15 mpr-10378 ic16 If they all checkout ok, then the problem could be in the circuit that addresses the ROMs itself.

Good work Olly, and some excellent guidance from Dave. How is the US side art printing coming on?
