I have linked 2 NBA, s and the scoring is all over the place ,game 1 pop bumpers score 2 points on 2 strikes , game 2 ,,, 14 strikes to score 2 points ,, tried swapping roms , going through adjustments making all settings identical ,, no change ,, then tried factory reset and burn in , that seems to have worked for a few games , but when we went back after a few hrs it now has game 2 scoring at a higher rate than the game 1 ,, th ed fault is the same but has moved to the other game , WTF , any thoughts PLEASE

Did you make you connection cable im going to make a shorter 1 and see
