Got this Pacland, Sidam version, in mint conditions for a repair
The game had some color bitplanes of the sprites shifted to the left as you can see from this pic
The sprites are handled by CUS29 and there are two 2149 rams connected.
Piggybacking a good 2149 ram on top of the one @3T restored good colours
Testing it out of circuit confirmed it was bad
The game had no other faults and was 100% fixed
