Animal Crossing: New Horizons Design Pattern Editor.

The editor was tested and verified with 1.0.0 - 2.0.0

As pictures are speaking more than 1000 words, you can see it in action here:


Here is a how to video by our moderator Greenie

It all started as a hobby project so don't expect constant updates. I can invest some time in it when I have the free time.

Latest version: 0.9.5p9

Features which are already working:
  • Loading the savegame and showing all of your design patterns.
  • Cloning of design patterns
  • Swapping of design patterns
  • Deleting design patterns
  • Importing a picture (png, gif, jpg, bmp, webp) as design pattern with different color quantization algorithms etc.
  • Importing ACNL, ACNH and QR codes.
  • Edit patterns with a lot of tools. Editing is happening in 32-bit and can be quantized to your liking.
  • Edit pattern supports layering and importing smart objects (images).
  • Support for full 24-bit colors. (of course you are still limited to a palette of 15 colors)
  • Supports transparency.
  • Save your designs as project files (keeping all layers).
  • Exporting a picture (as png, gif, jpg, bmp) to share it with others
  • Exporting a design as QR code (only legacy designs work)
  • Full support for pro designs (including legacy 3DS designs like the horned cap)
  • Preview of patterns in 3D.
  • Of course saving your savegame.
  • Windows X86 Support
  • Windows 7 Support
  • Mac OS X Support
  • Integrated online pattern exchange
Features which are planned:
  • Create a NRO hombrew to transfer the savegame without manual work required.

Hey, I've been using this for an hour or so now and it's working pretty well, thanks! But I have one question, a lot of qr codes that I try just come up blank, no design or info is loaded, just a white square. any idea what I could do to fix that?

Suggestions:
  • Background music, feels quite empty.
Currently doesn't work for me, i can launch it but when it reads the save file it stays on a blank screen and refuses to continue, so I can't use it. The tutorial works fine though.

I'm joking lol
Just quickly wanted to check if it works for me.

In fact it does work here. You've downloaded version 0.9.1?
This seems to be a tricky problem to solve.

Edit: Can you try to run the editor as administrator? It may be a file access problem. (I will add an error message for that in the next release)

Works! I know the problem, I was just using main.dat, I needed to use the whole save folder. Could you add that to the program so that it can detect this?

Of course :) But its also explained in the "How to export" section. But I will add a detection for that and inform the user via popup that the save file is incomplete and that all files needs to be present.
