The only thing that I found, in the memory of the game, was address with value of sense 30,000, but when I change value of this address to 34,000 or 65535 (decimal) ,after this, I can sense any enemy in the game.
Also, I found that the time in the memory card save can't go higher than 255 hours.
Also, I found in memory of the game, game time that also can't go higher than 255 hours. But this timer only works in field maps, he stops when player opens menu (when player presses triangle button), and stops in the world map, too.
