Harvest Moon: Friends of Mineral Town Cheats

Instead of giving Popuri gifts that cause money, give her weeds. She excepts them, and it will raise her heart total for you.

In the summer, use your level 6(cursed) fishing rod at mineral beach and you can catch a pirate treasure(rare)and sell it for 10,000 Gold.

In the fall, use your level 6(cursed) fishing rod at mineral beach and you can catch an Ancient fossil(rare) and sell it for 5,000 gold.

Starting with Year 5, then every 5 years after that (eg: Y5, Y10, Y15, etc.) visit the Peak of Mother's Hill on Fall 10 between 6PM and midnight to activate a serect event called the Shooting Star Event. Make the wish to double profits (option 3). The day will end. You then have until 5PM to ship as many things as you can. When Zack comes, he'll double your profits for Fall 11.
NOTE: Fall 10 MUST be sunny, or the event won't activate.

There is a place where you can get truffles for free behind the church, through the locked door on the right. All you got to do to access it is to be friends with Carter, give him mushrooms once a day for a season or so. During fall, go to the church, if you are good enough friends, carter wont be there and then you would go to the door and find its unlocked, after a short scene, you can pick Truffles and Mushrooms anytime you like! Truffles are worth a lot, take advantage of this plantation
