The game had way too much yellow on screen, almost impossible to see anything other than yellow.
I Traced blue/green circuit back to palette RAMs K8 and K9. Both looked fine on the scope so had to desolder the pair of them. The RAM at K8 failed a test . Socketed and replaced the faulty RAM with a 2018 and tested.

All working fine
