ROM Hack Discussion Animal Crossing: New Horizons -- NHSE Map Sharing Thread

RIALEKDI · Feb 3, 2026

Hello!
Is there a way to apply MyDesign patterns to existing islands when applying a new map using NHSE?
The patterns still don't apply.
and one more, I played it around 2022-2023.
Sadly, I don't have a Dream Address.
My brother broke his Switch, and I really want to find the data. Is there a way to find it using something like the MyDesign code?

Hey

Can someone dump this map, please? It was dumped before, but the link doesn’t work anymore

DA-7461-3536-2026

Thanks in advance!

Hello, I'm looking for a terrain that has an airfield almost in the middle, or completely in the middle, of the ACRE on the NHSE... Anyone know? Please let me know if you have any islands you're using right now... I'll be waiting.

안녕하세요!
NHSE를 사용하여 새 지도를 적용할 때 기존 섬에 MyDesign 패턴을 적용하는 방법이 있습니까?
패턴은 여전히 적용되지 않습니다.
그리고 하나 더, 2022년에서 2023년쯤에 플레이해 봤습니다.
안타깝게도 저는 꿈의 주소가 없습니다.
제 동생이 닌텐도 스위치를 고장냈는데, 그 안에 있는 데이터를 꼭 찾고 싶어요. MyDesign 코드 같은 걸 이용해서 찾을 수 있는 방법이 있을까요?

It's NHSE. Back up all the designs on the existing island, and LOAD it to the new island. And, turn it on to show the map. Press TRARRIN - MODIFY ALL. Export the design choices as well, turn on the new island and import the choices. Attached to the picture.

I'm having trouble loading my Animal Crossing: New Horizons save files. The game starts from the beginning after loading, instead of using the saved file. I have the latest versions of Atmosphère and JKSV installed on my Switch. Can someone please help?

I don't wanna promote my own app, but there is a tiny guide written to install and use it...
You need to be able to visit dream islands on your switch tho (i.e. be able to go online)

Can you please dump DA-2155-4715-3599

Thank you, but what does it mean that there is no metafile? What is it needed for?

I never had that issue but found this

Edit 3: problem was solved on GBAtemp. If you rezip the folder (not even necessary ig), don't compress the folder itself. Go into the folder and compress all the files together. If you compress the folder, it'll get compressed within the zip, meaning your file structure will be zip > folder > files which is no good. It needs to be zip/folder > files

Okay, thanks for the explanation but the imported save file was already unpacked and not a zip archive. The main thing is that the imported save file works perfectly and there are no problems.

Personally I recommend making a back up of my island
Use nhse to dump the map files if I want other map (not saves), change map files on my file and restore.
I strongly recommend don't use different saves at least on ACNH

Thanks so much for the tip. Unfortunately, I'm relatively new hacking ACNH and don't know the way around very well. Where can I find your island to make a backup?

if you use a dream island or another map, dumo/import the map files and if you need items
use the pockets storage or house storage, depending on what you need
pocket storage its only 40 items max
house storage i believe is 1000

RIALEKDI · Feb 5, 2026

Can someone help me?
I'll try using the dump method you posted.
My Switch is not compatible with Nintendo Online, so I can't go into other people's dreams. What should I do?

Hi, I’m sorry, I know you probably get a lot of dumb questions, but I’m trying to place map3.0 and it’s not displaying correctly. I don’t know if there was something additional I needed to do or not, because the items are very fragmented and bushes are in weird places. I’m on the newest version of NHSE. I don’t know if I needed to be on a specific version? I’m just following the video you posted on how to place them.

So my question is, how do you actually place this and am I doing something wrong?

Open your main.dat on nhse
Go to map editor
Dump/import
Import all acres
Select NHL files
Done

Make sure you are using latest nhse editor or acnh mobile spawner
