Sprites show wrong full lines at certain positions.
See the main player character rabbit and the enemies in this screenshot for example.
A visual inspection of the lower PCB shows a possibly damaged trace near 74LS194 @6M.
Comparing with a working PCB (another Springer) shows that the damaged trace should go to pin 4 of 74LS194 @6N.
Repairing the damaged trace brings back the sprites as they should be, no lines are visible anymore.
