Recently my CPS2 multikit (old version) starting having jailbars on the screen, I thought it was the usual loose connector but even when the plastic cover was removed and reconnected, the jailbars persisted. Thinking it might be an "A" board issue, I did a test swap and it was still no good. I read up on the forums here, that it could be the GPAL chip issue, so I swapped out all 3 with a working ones from another "B" board but still no good. I've checked the pins on the multi kit board with a multimeter and they are making good contact. It's leading me to think either the multi kit board or the B board is having the issue.
