Thanks, now it works perfectly. I had deleted the player 2 profile in the demulshooter GUI. The only thing I've noticed is that in mamehooker it only throws the led for player 1 (P1_LmpStart), but not for player 2, and P1_Damaged and P2_Damaged don't work either, like in the other games. A pity that I can only try it on Sailor Zombie, which is the only lightgun I have.
