I can now declare thia game as dead. I brought the board to an mobile phones repair shop because they claimd they have the right tools to reflow such things. All I got after is one brocken pad and some bent pins. I now had myself a go and removed the IC to check where the missing pad leads and an attempt was made so solder it back on. Now it dose even less than it did before.
Either the heat killed it or something else.
Rest in peace Namco game.
