Harvest Moon ps2 Wonderful Life Special Edition Cheats?!?

I play harvest moon for the ps2 and so far I am in the first year of my little boys birth……I married Lumina and I have a sheep, cow, horse, cat, dog, and chickens. I let all my animals in the pasture during the day and let them in my house/barn/chicken house at night or when it is raining or snowing. Does anybody know of any cheats that ARE NOT online because I checked EVERY website that has cheats for this game. PLEASE help me and make sure they WORK!

PS- I am in the 2nd year because I just got the black cat so is there still any way I can get ducks in my NEW pond…..?
