FYI, animal crossing sends via play report hashes of the executable contents.

Cheats like this one which write to .text will result in Nintendo receiving a bad hash the next time you go online (even if you are in airplane mode while playing), and therefore risk bans.

This is the first I've heard of this. How can I tell which cheats write to .text and which do not? I don't use this specific cheat, but I'd like to make sure I'm not using any others that risk a ban.

I don't play online very often but when I do I make sure to boot to stock. Sounds like that isn't enough though with cheats like these.

Reasking since this is got buried. I don't think it's been answered but seems important to lower the risk of getting banned.

I tried to use NHSE to delete a villager; doing so caused the save file to corrupt and refuse to load. Is there any reason why this may have happened?

Anatomy of an Item Code:
It might be a bit more complex than this in some situations or with some more specific items, but this should get you started.

Simple Item Code: (no durability or customization)
[Slot 1 x10 Nook Tickets]
04100000 AC3B90C0 000016DB
04100000 AC3B90C4 00000009

16DB = Item ID for Nook Miles Tickets -- change this to what you want from the Item ID Doc
09 = Item quantity (1 more than shown; 00 = 1 Ticket, so 09 = 10 Tickets)
If you change this higher than the max, it will default to 1. So in this example, Nook Miles Tickets max stack is 10 -- if you set this value to 0A (10 in hex), that would be 11 tickets, so you'll only have 1.

Tool Item Code: (durability and single-dimensional customization)
[Slot 1 Colorful Fishing Rod]
04100000 AC3B90C0 00002118
04100000 AC3B90C4 000x000y

2118 = Item ID for a Fishing Rod
0x = Item durability, counting up (i.e. 00 is max durability)
0y = Customization color; 00 should be the default tool color, in this example, a blue fishing pole.
So far, no items (that I'm aware of) that have quantity should have either durability or customization.

Furniture Item Code: (two-dimensional customization)
[Slot 1 Wooden Stool]
04100000 AC3B90C0 00000D79
04100000 AC3B90C4 000x00yz

0D79 = Item ID for a Wooden Stool
x = Custom Print value (0 = No Custom Print; 1 = Custom Print) CHEATING CUSTOM PRINTS NOT RECOMMENDED (seriously, just use some customization kits)
y = Customization Value 1 (in this case, cushion color)
z = Customization Value 2 (in this case, wood color)


Big thanks to @Lionheartwolf for clarifying and testing how durability/customization work.

EDIT: I've also quoted this in the main post. I intend to write a basic item code generation web tool to stem the people asking how to edit a code in a basic way, or to make one for specific items, but in the meantime, anyone helping can direct them to this post, or to the OP.

Anyone found a way to unlock the camera outside as if you were in a house. I really need it for a project and so does Shesez (YouTuber)
Hey I just saw the boundary break video and are you sure the one that made the Walk through walls code and the one who made custom firmware is credited properly? I saw no such mention of custom firmware, or even Yuzu emulator or anything like that in the description. Just a vague link to a modder's Youtube channel who I doubt has anything to do with modding Animal Crossing. I think it would be more honest if Shesez would actually credit people properly instead of what they did. Not that I care that much about youtube but if you're gonna involve modding in some video you might want to be careful.

Here's the video right here:

As you can see there is no mention of either an emulator or custom firmware or EdiZon or cheats and no credit to the one that actually made the cheat.

So for those rare fish spawning codes... does anyone know which codes correspond with which fish? So far, testing out the first 6 codes, I see the following:

1. Dorado
2. Popeyed goldfish
3. Char
4. Stringfish
5. Gar
6. Arowana

Also, looking at the code, all the fish spawn codes are pretty much the same except for a couple of lines, but they don't seem to correspond to the fish in the pastebin list... I wonder how I could customize them to get the fish I'd like to spawn spawning.
Odd, I cant get any fish besides Dorado. Am I doing something wrong?

Only use 1 rare fish code at a time. If you want a Stringfish, turn on JUST this code and sprint around the existing fish to make them de-spawn. Also remember that the rare fish have HUGE shadows, and it's just an increased chance of seeing them, it won't be every fish.

Code:
[Fish spawns incr. + avail. anytime - Stringfish]

Anyone have a code to clear inventory? I apologize if this has been asked already! Thanks to everyone for their efforts towards this game!

Is there a list of the furniture variations? I understand that they're set by quantity, I'm just wanting to know what variations actually exist.

That list is literally tens of thousands of different things. Make a wiki, or start experimenting cause nobody is going to make a list of every single variation of every single item in the game.

That works! Thank you much for all the codes!

Works for me on 1.1.3, idk. Code is code, it doesn't variate. Turn on "no common fish/disable sea bass" code as well, and maybe visit a mystery island. I only used it once for the Stringfish because of March expiration, and I leave the "disable sea bass" code on as well. Rare fish #1 is definitely the Dorado.

Does anyone know how to enter the correct meta data to use on https://acpatterns.com/editor.. it says you need a AC:NL file, but never played it. Is there away to make patterns that can be edited in game?
I did this with a combination of the tools available for importing patterns as well as hex editing the decrypted save file myself. Currently the stuff I can do with hex editing covers things that the tools don't support just yet.
