Ms Pac-man bootleg player 1 controls are not working

Archived from groups: rec.games.video.arcade.collecting (More info?)

I have a Pac-1/Pac-2 bootleg board with Ms Pacman roms on it. I t was
working fine until last night. Player 1 controls are not responding.
No start, no up, down, left or right. Player 2 start works but I do
not know about the other controls (The adapter only has player one
controls wired up except for player 2 start). The board also has the
row 6 single eprom hack on it and none of those wire look lose or
shorted.

I read the 74LS367 at 8-E may be the cause, but I do not know how to
test it. Can someone explain to me what I should look for or any other
tips that might help me track down this problem?
