First, change the date to 8th of april, or whatever day "Zipper T Bunny" is there (if unsure, check the calendar on the animal crossing website to see the correct day). There is an easter egg hunt. Dig up all eggs and trade any "bunny foils" with zipper t bunny in front of the town hall. Put any candy in a place where you will remember ( Infront of your house, the town hall, able sisters etc). You will need this for later.Constantly carry a catapult because there will be lots of presents floating in the sky to shoot down. Once you have collected all the bunny foils and traded them for prizes, save and quit. Change the date forward one day and then sell all your prizes to nook for 50,000 bells or more (I am unsure of the exact price- about that much). Then, go back 1 day to the easter day and the hunt will have started again. You can re-do the hunt, sell the prizes and get TONS of money.
The candy you saved is to get more money. Change the date to February 20th and go to the town hall. It should be the festival and there should be a dancing bird called pavé, who will ask for different coloured candy to swap for a prize. Use the candy you saved up and give it to pavé - wants 3 pieces of 1 colour candy at a time. She will give you a prize. Sell these to nook to get lots more money. If you didn't save any candy, then you can play mini guessing games with neighbour animals to get some.
Hope this helps. I managed to pay off my mortgage easily with money I earned from this.
WARNING- MAY CAUSE WEEDS. DON'T SAY I DIDN'T WARN YOU......
Ar
Sell cherries, or catch fish. Gyroids sell for a very high price too.
Make it Christmas Eve and find jingle once you get 5 things from him go and sell them you'll get about 120,000 bells or dig and find fossil and get them checked and them sell them there about 5,000 bells each
There are no Cheats unless you count changing the date which has the downside of Weeds and loss of Plants. The only way you can cheat is to get Action Replay and even then you'd have to start your town a new.
In December you have a acorn festivle. You can find a lot around trees there.
sell fish, bugs, shells and fruit
You can sell fruit off of trees, fossils and shells on/in the ground, and sometimes when you shake an empty tree, 100 bells falls out, but other time you get nothing or stung by a bee.
There is something you can do: go to the bank machine, put all your money in, save you game. then go back to it. Set the clock to January 1st, 2000, go to the machine and see how much money you have now. Actually there is a 30,000 bell code, but the cheat listed above may get you more money. There is no actual "cheat code" that will get you more than 30,000, though. The cheat code is WB28pARAcnownUjMCK%hTk8JHyrT, and for 100 turnips the cheat code is aPShDyYoeR685bafcAlkwcRCmqi3. If you tell Tom Nook the same code three times you could get 90,000 bells, or even more! This allows you to pay off your mortgage really fast and to remodel your house. You could add a basement, make your rooms slightly bigger, change the color of your roof, and more!
There is no actual cheat but while playing crib gear, you can press the shuffle button 3 times and get a lot of money, fast for playing the game. Up to 1000 zbucks a day.
You can use action replay or sell fruit by rewinding and fast forwarding the time. You can also try rewinding time to as far back as you can then put all your money in the bank, then fast forward time as far as you can and then go to the bank and you should have lots of money. You can do this as many times as you want the only problem is all the weeds which will need picking ;)
Well you can do a cheat by looking it up on youtube or if you are really good at it
Sorry, no... Unless you want to use a emulator, but that is not official or anything and needs a fast computer
