Symptom: Main sprites are either breaking up and parts randomly appearing all over the place, or main sprites okay but whole or complete pieces of other sprites randomly popping up
Diagnosis: Self test didn?t indicate a RAM or ROM problem, but determined that the outputs of the 6116 ?skinny? RAM at location I3 were intermittently flaky. That RAM later started to show up in the self test as faulty
Cure: Replaced 6116 RAM at location I3

Symptom: Parts of the letters missing on the text of the self test screen, plus ?sparkles? appearing in the graphics along with variable sprite faults
Cure: Some poorly connected pins on the surface mount Konami custom ( 051962 ) at location J16
