Quoted from Cherga:Reflowed the header pins and the display issue is resolved however a new problem has come up. The game will boot, GI lights come on but on the master display and P1 displays there’s a rolling counter. The game just keeps cycling through this. If I boot with the test switch in manual, the game does nothing. Pressing the diagnostic switch on the MPU yields both LED’s flashing twice then going off. Thoughts?
Did you get the two 4 pin connectors J3 and J4 in the right place on the upper left corner of the MPU board? They might be swapped.
