Quoted from pindoc1:Players 2 and 4 displays will also slightly flicker every 5 seconds or so.
The flicker is normal if you have a stock MPU. After I installed a ni-wumpf (an after market MPU) my displays were rock-solid. I assume any after market MPU would fix the problem, but I've only tried the ni-wumpf, so can't comment on the others, but have only read good things about all the after market MPUs.
There's a bug, for lack of a better word, in the original MPU that causes the flicker in displays 2 & 4. I've traced the flicker with a logic probe all the way back to display control chip output at U5, and can see the logic probe flicker off at the same time the digit flickers. To my knowledge, there is no known resolution to fix the original MPU. It may be a coding issue, or it could be something else.
Quoted from pindoc1:All of the displays pulse brighter and dimmer,
I'm not sure about this one--some owners have tried grounding the displays along with the other ground modifications and had varying success. The display grounding had no effect on my game--but I did not notice this problem on my game.
