Cheats: Animal Crossing
Update: Universal Codes! Grow a money tree, find a golden axe...these things do not compare to the awesome power of unlocking NES games.
Getting NES games
Talk to the townspeople until they ask you when your birthday is. Most of them will say something similar to "How would you like a train set for your birthday?" Answer "Yes" and you will put in your birthday. On your birthday, one of the townsfolk will be outside your house. He or she will present you with a NES. For example, Virgos will get Donkey Kong.
Money Tree
Find yourself a glowing piece of earth and dig it up for a money bag. Plant the money bag into the hole and eventually it will grow into a money tree.
Golden Axe
Maintain your town rating at "Perfect" for two weeks.
Golden Butterfly Net
Capture all 40 types of bugs.
Golden Fishing Pole
Collect all 40 types of fish.
Unlock Golden Shovel
Buy two shovels and find a piece of glowing earth and dig it up. Next, plant a shovel in the glowing earth.
House Upgrade
First, pay your debt to Nook. When you talk to him, he will thank you for paying it off and offer you a bigger house. After answering 'yes', wait a day, and you shall be rewarded.
