Mmh... do U think it would be possible to create a code, that let the game think your the owner of a villager house, so U could take or place their items?

I'll also like to remove some fishes from some villagers houses. NHSE furniture editor seems not doing the work.

Best way to hack bells on sx os?

This tool can update the game database by itself
If you need other languages, you just need to make database tables according to the specifications and load them
Database table production specification: column a = ID, column B = classification, column C = name, column D (can not be filled in) = remarks
1.Make the above standard database table
2.Open "Switch Animal Crossing Cheats Generator Tools.xlsm"
3.Select "Update"-"Edit Link"-"Change Source"
4.Select your own database table

If she's in the thought process stage either don't talk to her or talk to her and ask her to stay. Done. If she's already packed in boxes, then in NHSE there's a check box for "Moving out" and you'll want to edit her flag #24 and set it to 0.

I just wanted to know if NHSE can modify a player or map flag that determines which NPC has the thought bubble. I know that it can force people to move out but that's not what I'm looking for.

Yeah, seems editing villagers items is the only thing that's not working in the SE.
Would be cool to find a way for editing items in their house.

Hey guys,

I just tried to "create" my own cheat for ACNH by using other cheat and code generator. I'm a SX OS user. The last cheat I download isn't working since the 1.2.0 update, that's why i'm trying to do this.

That's all my code :

But when i try to cheat (with SX OS), i have this message : "There was en error parsing the cheat files". Do you know why ? The .txt is ok (20CA968C082118C2) and he is well placed.

Thank you and sorry for my bad english.

I just wanted to know if NHSE can modify a player or map flag that determines which NPC has the thought bubble. I know that it can force people to move out but that's not what I'm looking for.

Short answer is no.

Hey guys,

I just tried to "create" my own cheat for ACNH by using other cheat and code generator. I'm a SX OS user. The last cheat I download isn't working since the 1.2.0 update, that's why i'm trying to do this.

That's all my code :

[DylanDsrt]

My guess is that line, but I don't know SX OS, or that blank cheats are for sure not allowed.


In other news, I prettied up my code table, and followed some of the practices Microsoft suggests for fast HTML tables: https://mpql.net/tools/acnh/codes/item-list/

 

[Deleted User]

Is there a code to make specific fishes spawn?

 

[FabioCapela]

Untested (I've researched it using direct memory writes), but this code should force a flower in slot 1 to, when planted, breed next day:

02100000 AC4723D5 00008019

The address is that of the slot you want to affect +0x5.

Warning, don't ever use it with anything but flower plants in the affected slot(s). It has a high chance of messing the item up, including running down the durability of any tool such that it will break on next use if it can break and isn't a golden axe, shovel, or watering can. Also, neither flower seeds nor picked flowers count as flower plants.

How it works:
For flowers the lower byte of the quantity is the genetics, but the high byte is the number of days the flower has been watered (apparently capped at 31, or 0x1F); this number is set to zero when the flower is dug up, but not when it's planted, meaning if you somehow manage to set it on a flower in your inventory it will persist when planted. The chance of the flower reproducing when the day changes is defined by how many days it has been watered (and how many visitors watered it); any value over 22 ( 0x16) is supposed to guarantee it reproduces the next day, I picked 25 (0x19) just to have a safety margin.
The 0x80 (which goes into the first durability byte) signals that the flower has been watered.

 

[DylanDsrt]

Thank you Mopquill.

 

[spookyporo]

I'm posting it again, since now one answers me:
I get troubles using the NHSE, since all my editing doesn't apply to the game itself, and yes, I used JKSV for both extracting and injecting the save files.
Can someone help me, please?

i found these cheats a ways back in the thread. could anybody tell me why i get 'no cheats found' in the menu?

Because every single cheat in there is broken this is someone else's cheats they all have too many characters within the codes like 9 digits everywhere.

Honestly the only thing I can think of is you aren't actually restoring the save file back. Or you are not actually saving the edited save via the save editor.

yes, since when i try again to edit after the first process, the own app shows me the editing i did before, but in the game, no change is done.

Untested (I've researched it using direct memory writes), but this code should force a flower in slot 1 to, when planted, breed next day:

02100000 AC4723D5 00008019

The address is that of the slot you want to affect +0x5.

Warning, don't ever use it with anything but flower plants in the affected slot(s). It has a high chance of messing the item up, including running down the durability of any tool such that it will break on next use if it can break and isn't a golden axe, shovel, or watering can. Also, neither flower seeds nor picked flowers count as flower plants.

How it works:
For flowers the lower byte of the quantity is the genetics, but the high byte is the number of days the flower has been watered (apparently capped at 31, or 0x1F); this number is set to zero when the flower is dug up, but not when it's planted, meaning if you somehow manage to set it on a flower in your inventory it will persist when planted. The chance of the flower reproducing when the day changes is defined by how many days it has been watered (and how many visitors watered it); any value over 22 ( 0x16) is supposed to guarantee it reproduces the next day, I picked 25 (0x19) just to have a safety margin.
The 0x80 (which goes into the first durability byte) signals that the flower has been watered.

So from what I'm gathering, flowers are structured like so:
WW WW WW WW XX XX YY ZZ
where W is the ID of the flower, X is the genetics (what is genetics, which color it is?) Y is the number of days it's been watered, and Z is the flag on whether it's been watered.

Flip the endianness and you get a code like:

04100000 AC4723D0 WWWWWWWW
04100000 AC4723D4 ZZYYXXXX

Is that correct?

As for genes, I see something like R1, R2, Y1, Y2, W1, W2, and S1, S2?

Not quite. It's 00ZZYYXX; 1 byte (XX) for genetics, 1 byte (YY) storing the number of days previously watered (and perhaps other things, as there are 3 bits unaccounted for), and the flag indicating it was watered in the current day is in the first durability byte (ZZ).

I'm fairly sure the number of visitors watering the plant is stored there somewhere, but since I'm not playing online I don't have an easy way to test that.
