Harvest Moon
Note: This is the Game Boy Color game, not to be confused with Harvest Moon for the classic Game Boy .
Infinite eggs
Obtain a watering can and water an egg that is near the shipping box. It will turn into a fence. Pick up the fence and it will change into an egg. However, the fence will remain allowing unlimited eggs to be obtained.
Hints
- Extra crops
Capitalize the first letter of your name to get eggplant and carrots as extra crops. Leave the first letter of your name in lower case to get broccoli and peanuts. Replace the first letter of your name with a symbol, such as the heart, to get all four crops.
Extra crops and seeds
Choose to be a girl character to receive extra crops and seeds.
Extra $1000
Click on the cupboard after starting the game to get a quick $1000.
Extra money
You can get extra money by plowing the ground. When you find money remember that location plow it again the next day. This only works once a day. Put a fence on top of where you plowed, then take it off so you can plow again.
Protect your fences
Leave your dog out everyday and your fences will never be broken unless it rains or snows.
Feed the sprites
If you feed the sprites everyday they will be nice to you. They will also give you a power berry during the earthquake.
Super Sickle
On one day a sprite will ask if the sickle is strong enough. Answer “Yes” and he will upgrade it the next day.
Super Hoe
On another day a sprite will ask if the hoe is strong enough. Answer “Yes” and he will upgrade it the next day.
Golden Axe
After the earthquake, go all the way up in the caverns and throw your axe in the water. The Harvest Goddess will have a Golden Axe and ask if it is yours. Answer “No” and she will give it to you.
Save time
When something is bought, buy as much as you can afford so you do not have to buy the same item again when it runs out. Only ship crops during the day, and feed and water everything at night.
Save wood
You can save wood for your fences by using the small rocks, so do not break them or throw them in the ponds. They also can not be broken by the rain or dogs.
Note: You must have a 2.1 or higher version of the Game Shark to use these codes in a Game Boy Color system.
