- Please try reading the other replies or using the forum's search function before asking a question. Most likely, your question has been answered.
- Avoid asking about "will I get banned if ___ " questions because as of right now, nobody knows. Nintendo sends a lot of information from your game to their servers, but it's unclear how that information is used.
This is a thread for reverse engineering ACNH, studying cheat formats, etc. It's become a bit of a water cooler, but please avoid using it as a personal help thread, especially for questions that have already been asked. Also, please check to see if one of these handy topics answers your question, or would be an appropriate topic to ask your question in.

Hello everyone,
Given that the game has released in some parts of the world and officially releases in a few days, I'd like to begin this journey of reverse engineering the game.
Lets use this forum page to break the game down via reverse engineering and create cheats and talk about it.
Also please talk in here about glitches or bugs that have been experienced.
I have given perms to @Ultimos54 ,@patjenova ,@Mopquill and @Vapp13 to help keep this post up to date.

@Ultimos54's Cheat File Guide:
Atmosphere: Download the attached file and extract it. Open your SD card and navigate to Atmosphere and then contents. Place the extracted folder here. Next, you'll need to download a homebrew app called Edizon . (Note: If you cannot see any codes, remove some codes from the txt file that you won't be using. It won't see any codes if the txt file is over 32kb) Extract the file "EdiZon.nro" to the switch folder on your SD card. Eject your SD card and insert it back into your Switch and boot into your CFW. Launch Animal Crossing New Horizons. Once you're in-game, press the home button and select album. (Depending on how you have it configured, you may need to hold R while opening the album to get into homebrew) Select EdiZon and click the blue C. Your cheats should be there ready to use.
SXOS: Download the attached file and extract it. Open your SD card and navigate to sxos and then titles. Place the extracted folder here. Eject your SD card and insert it back in your Switch and boot your CFW. Launch Animal Crossing New Horizons. Once you're in-game, press the home button and select the album. Navigate to the cheats section and your codes should be there waiting for you.
Save Editor: WE AREN'T THE CREATORS SO DON'T ASK FOR FEATURES HERE, THE THANKS GOES TO SCIRESM AND HIS TEAM ON TWITTER(THE PEEPS WHO MADE PKHEX)
Save Editor is in the works on :https://github.com/Cuyler36/MyHorizons
SAVE EDITOR IS OUT: https://dev.azure.com/project-pokemon/NHSE/_build from the creator of PKHex he got help from the guy in the first link
Save Editor Guide:
Azure Site:
1.Click on Pipelines
2.Where it has the title under Last Run click it
3.Under related Tab click published
4.You should see a file name, scroll your mouse to the far right of it to see a button,click it to download the file
5.You should get a folder,decompile it to get the files,inside there is a file called NHSE
6. Open up your save folder to the point where it can see both main.dat and mainheader.dat
7.Your save should load,go ahead and have fun editing,once done editing click file save and DONE
9.Restore save to switch
USE JKSV to backup/restore saves,Checkpoint and EdiZon do not work. Also, do not run it in applet mode as applet mode doesn’t support the keyboard is SXOS.
Save Editor Bugs Currently and their FIXES:
FIX FOR MAX ITEMS: If max is 30 set to 29,basically for max just set it to -1 below the max
CLOTHING AND CATCHPHRASE FIX:After talking to Isabelle and complaining about the way the villager's dresses and the way they talk, it makes them change back to what they meant to be (checked with amibo pedia).
CRITTERPEDIA BUG IS FIXED IN NEW VERSION OF SAVE EDITOR WOOOOO: Go into received items and click give all bugs and fish, its adds them to the critterpedia but not to the milestones
HOUSE'S NEED TO CHANGE TO NEW EDITED VILLAGER ON SE:
The fix was found by @hentaikun @Blasetzmt and @eskil ,they found that if they deleted the villager in the SE, the game would make their plot available again, to which then once you find a villager via a nook miles ticket/ammibo or campsite site visitor you could just edit the villager in the SE when they are on their way to your island.
FIX :Provided by @eskil is a blank villager file for the SE to import to clear/delete the villager from your save to which once done just find another villager via one of the methods stated above and whilst they are coming just edit them in the SE as they are coming or before hand if you want the next villager to be what you want to overwrite their data
The blank villager file is now provided in the cheat folder thanks to @eskil
Cheat Folder is provided below and is property of those that contributed codes and files such as @Ultimos54, @patjenova, @Mopquill, @Vapp13, @eskil, and @Traiver. We will try to keep the folder up to date as possible.
Below is Ultimos54's compiled file of cheats; please note that it is outdated. Consider checking the cheat database instead, linked at the top of this post.
