Is there anyone here could assist in the repair of my beloved Raiden PCB.

It has some issues with background sprites not drawing where they should. I would hazard a guess it is an indexing error that changes as the board warms up. from what I understand the chip that drives the background sprite indexing is custom.

Here are some pictures that may assist in the diagnosis.

Thanks.
