One game that went down was Punch Out (with the free play chip) When you started a game it would get to the point where it should say "Ladies and Gentlemen introducing Glass Joe" but it wouldn't say it, it just froze right there, played with connector and restarted and got same thing. Any punchout guys ever have this problem? Second game is Baby Pac, monitor works in test mode but won't display the game, Third game Battlezone-game plays but screen is real shaky, Then there were to mames with Arcade monitors that just went to "black screen" after sitting idle. Oh, almost forgot Cruisin usa also looks blurry now.
